transmission cooler info and derale trans cool pans,

OVERLY HOT TRANS FLUID TEMPERATURE QUICKLY KILLS, A TRANSMISSION, SIGNIFICANTLY REDUCING TRANSMISSION DURABILITY, AND I'D POINT OUT THAT REDUCING THE TEMPERATURE OF TRANSMISSION FLUID ENTERING A RADIATOR HELPS REDUCE HEAT LOADS ON THE RADIATOR ,WHICH TENDS TO REDUCE ENGINE OPERATIONAL TEMPS.

ITS GENERALLY SMART, too Do all you can to keep fluid as cool as possible.
Higher stall converters produce more heat so they need more cooling. YOU may not need the Biggest cooler that can be installed , but you obviously should be calculating what will be needed and have that installed, and coolers with an auxiliary electric fan are a huge asset
If your thinking of adding an oil cooler ,the first question ID have is WHY are you adding an oil cooler and WHAT are your current oil temps that require one? the same question applies to trans fluid coolers, but its almost mandatory to add a trans fluid cooler in the case of a higher stall converter as most stock transmission coolers are barely adequate to maintain reasonable temps under normal driving conditions on the stock components.
most hydraulic supply shops can very easily fabricate flex hydraulic lines with matching ends at any length required,and theres plenty of auxiliary transmission fluid coolers on the market and from experience I can assure you that if you need a trans cooler the type with the built in fan and at least 1/2" or AN#8 0r in a few cases AN#10 fittings are by far the best choice,simply because, it allows you to expose a great deal more of the trans fluid to the cooling effects of the surface area of the auxillery oil/trans fluid cooler far faster and more efficiently, with far lower restriction to flow rates, and obviously youll need to carefully measure where your going to mount the cooler and run the lines before ordering a cooler but the larger the surface area the better in most applications.
a restriction to flow will generally be the part of the connecting lines with the smallest cross sectional area, if you look at most automotive oil or transmission coolers they have AN#6 (3/8")or AN#8 (1/2")connections, so lines significantly larger won,t do much for increasing flow rates

DEEPER transmission oil pans come in a wide range of designs, some have air flow tubes to aid trans fluid cooling, Ive used them in the past,but these tend to reduce under car clearance so measure, GROUND CLEARANCE carefully WITH TWO PEOPLE IN THE CAR, and think about speed bumps and raised manhole lids
keep in mind you need to know your homework, youll want to jack your car up and place a 2x4 with a block of modeling clay under the current transmission oil pan an then jack the car down, and have you and a friend sit in it to get a realistic idea as to current transmission oil pan to road clearance before thinking about use of a deeper oil pan on the car,youll want to maintain a 3.5"-4" MINIMUM road clearance to avoid damage from most road hazards like taller than usually speed bumps and manhole lids etc. if you can,t drive over a 3 foot long section of 4x4 lumber (which BTW measure about 3.5" x 3.5") in the street without hitting the transmission or engine oil pan your unlikely to clear some of the taller speed bumps and manhole covers projecting out of road surfaces
If you decide on a pan with those air flow cool tubes ,that can keep the cool air flow thru the hot trans fluid youll need to keep the tubes free from road crud blocking them,if they are free to flow air, they help, the problem is that keeping the hole clear is a bit more difficult than you might think if you live in an area with dirt roads or (MUD DOBBER WASPS)
when I had that style transmission pan I had to put the car up on the lift about once a week and power wash out the tubes because I drive on a few dirt roads, regularly, and on a car that has the oil pan on the transmission less than 5" off the pavement the holes tend to fill with crud fairly fast, I eventually swapped to the cast aluminum pan with external ribs that increased the surface area as it was stiffer, leaked less, at the gasket mating surface and was less maintenance.

IVE FOUND THE USE OF BOTH A REMOTE MOUNTED, FAN EQUIPED TRANS COOLER AND
THE TALL CAST ALUMINUM TRANSMISSION PAN THAT ADDS A FEW QUART CAPACITY, WITH ITS RIBBED PAN SURFACE THAT ALLOWS HEAT TO DISSIPATE EFFICIENTLY
(IF YOUVE GOT THE REQUIRED CLEARANCE HELPS)
BUT ITS ADDING A DECENT , ELECTRIC FAN EQUIPPED TRANS COOLER THAT KEY, TO KEEPING THE FLUID TEMPS UNDER 180F for LONG TERM DURABILITY
Image
Image
Image
Image
Image
you can,t generally see a extended capacity transmission pan so having a chrome plated one that won,t dissipate heat well makes little sense, and the stamped steel ones tend to flex and leak far more easily than the cast aluminum ones with the ribs do
I removed my (spare tire) and installed a rather large trans cooler with a powered fan .in its place along with a 2 quart aluminum trans pan adding a bit more capacity, this deeper oil pans only about 1.5" deeper than stock but it requires you to think about the reduced ground clearance because a c4 corvette trans pan has already minimal clearance to the road surface, with two adults in the car, making trans oil pan to road surface rather close to the ground

Image


one of the first things I noticed when I installed a 8 quart baffled oil pan (further modified with extended sump) and a transmission and oil cooler on my car was the very noticeable drop in engine temps, in fact the engine had a hard time getting the oil temps up to 215F which is required to burn off moisture in the oil that gets into the engine if it sits for days in Florida, the cure was installing a 190f t-stat and a bye-pass/return on the oil cooler, that bye-passed the cooler with about 90% of the oil flow routed to the cooler until the oil got hot.
if you want to keep the temp from making wide swings as the car runs..
there are 190F-195F t-stats

http://www.ecklers.com/corvette-low-tem ... -1995.html

and optional sensors you can use to turn on the fans at lower temps like 195f-200f





Image
the tubes with air flow cooling holes look like a good idea but in the real world they plug up with mud or leak most of the time, get the ribbed aluminum pan and save yourself the grief

they work ok at first, but make speed bumps and some driveway entrances a problem and it rarely takes long for crud to plug the tubes and then they are nearly useless, one good mud puddle splash of mud,and your efficiency drops off, a couple and your clogged, I think your best solution will be a electric fan equipped trans cooler, if you've got only paved roads with no speed bumps and your willing to pressure clean frequently you might be ok, at least until the first tall manhole cover rips it clear off.. look under your corvette now with two people in it, I doubt you'll see 4" clearance under the trans pan, make it 1.5"-2" lower and you've got a huge potential problem, save those pans for trucks with more clearance

your best off installing a transmission fluid cooler of significant size to cool the trans under high stress/high heat load conditions,that has a separate electric fan and a thermostatically controlled switch that routes coolant thru the aux cooler once it reaches 180F, so it can,t get any hotter
if you have a performance car with a high stall speed converter, you might want to be discussing the installation of a remote mounted trans fluid cooler on your car, now it might not be mandatory but its always a good idea on a car that has a high stall speed converter as they generate a good deal more fluid heat than a stock transmission.


heres the cooler I installed on my corvette, It was the most efficient one I found that would fit at the time I looked, but it has AN#6 lines, it works just fine but if I had the chance ID select a slightly smaller and thicker cooler with larger line size , when I measured the corvette for the trans cooler I carefully measured the available space I intended to use and selected the largest most efficient trans fluid cooler that would fit in that space but forgot about the room that was required to route the trans fluid lines and fittings , making installing it in its intended location a true P.I.T.A. so I wound up mounting it where my spare tire goes normally in the rear of the car, (NEW GUY STUPID MISTAKE), I,m pointing out so you might avoid that little flaw in your plans should you choose to install a trans cooler

http://www.summitracing.com/parts/PRM-12318/
Image

BUT having learned a good deal, since that time, if I had to do it over I would go with a slightly smaller size cooler with larger AN#8 lines if I was doing it today

keep in mind automatic transmissions tend to add a significant amount of heat to radiators that use the lower section to cool the transmission, adding a large efficient trans fluid cooler to the car can also significantly reduce the heat loads on the radiator

many guys don,t realize that adding an oil and/or a transmission fluid cooler, with its own fan and radiator that allows those liquids to be cooled separately, to your engine and drive train, significantly reduces the heat load on the radiator, and generally allows the engine temps to decline noticeably. in fact just adding a high volume oil pan and a transmission cooler can drop your engine coolant temps 20F-30F in many cases
Image

Image
remote mounted oil filters can be used along with an oil cooler to to increase transmission cooler efficiency, and the remote filter and cooler used on a transmission also tends to increase fluid capacity ,and as a result the systems cooling efficiency as the longer the fluid remains in transit outside the trans dissipating its absorbed heat, the use of a auxiliary fan equipped fluid cooler on a performance transmission with a high stall speed converter tends to significantly increase its potential durability.
Image
a rather common issue with adding oil coolers, is that many of the coolers available can significantly restrict fluid flow because of the small restrictive internal cross section of the internal tubing, AN #6 and 3/8" tube coolers can be quite restrictive, the AN#8 are better but DUAL AN#8 coolers and AN#10 lines generally work the best, and there's also frequently limited space to position a cooler in the outside cool air flow mandating a powered fans.
the solution to both issues can and frequently does require use of two different oil coolers but placed in series this can further increase flow restrictions, the solution is in use of larger internal cross sectional area,transfer lines and mounting the twin coolers in parallel thus doubling the effective cross sectional area reducing the flow restriction the cooler potentially could produce if used in series

"Did you see a noticable drop in temp with the derale pan? "

at first it dropped temps about 15 degrees, after a couple weeks temps were back to orriginal levels, I flushed out the tubes with a high pressure car wash wand and temps dropped some but not all the way back, I closely inspected the tubes and found they were partly blocked even after repeated cleaning, so I pulled the pan , added an aluminum ribbed pan that held about a qt more than stock and installed the trans cooler, its been fine since.
btw at first I had a dual trans and oil cooler ,(like below) but I quickly found that I needed a transmission cooler but not an addition too the factory oil cooler
Image
Image

BTW HERES AN IMPORTANT TIP, IF YOUR INSTALLING A REMOTE OIL COOLER, IT is really common for guys to use lines that are far too small, that restrict flow oil flow or select a transmission or oil cooler that has to small of internal passages, shop carefully you want a MINIMUM of 1/2, or AN8 line size and 5/8" or AN10 is BETTER.

A common mistake is to think that a straight -6 fitting and a 90 -6 fitting of used on the same hose should both have the same inside diameter. They do not. A hose with a straight fitting on one end and an angle fitting on the other end will have different inside diameters.

Im many cases adding a deeper transmission pan that adds two or more quarts will lower the average transmission temp. at least 15 degrees, while its certainly not as effective as a trans cooler with an electric fan, but far better than nothing at all!, and you don,t need to run coolant lines, just be aware that if theres limited ground clearance under the car, a deeper trans pan may be a problem when speed bumps and steep driveway access is encountered

keep in mind you can install a heat controlled valve that routes cool trans or engine oil back to the engine or transmission but one either fluid heats up it routes the hot fluid thru the cooler

Re: derale trans cool pans

Postby grumpyvette » November 10th, 2008, 8:51 am

Ive already sold the dual set up,......the dual set up was fine for cooling the oil (run thru the smaller side of the cooler)\
(probably a little too effective in fact as it was hard getting up to the minimum 215F)
and it worked "ok" on the transmission fluid, (run thru the 4 pass side) but it was not as effective as I hoped it would be,as under hard accelleration the trans temps breifly peaked higher than I wanted) so I swapped, to the larger single use 6 pass unit. for the transmission fluid. and everything appears to be better, as the trans fluid temps stay more consistant.
keep in mind high trans fluid temps always lower the transmission life expectancy, especially if your the average guy who beats on the trans and engine occasionally.
I think the main reason most guys don,t have an aux trans cooler is that they don,t have a good accurate trans fluid temp gauge in the car and have no idea how high the trans fluid temps get under hard accelleration, or understand what those temps do to transmissions relieability

yes its very much worth the cost/effort, adding a deep pan dropped my trans oil temp 10-12 degrees.. while that may not sound like much it potentially increases trans life significantly, 30% or more and YES it sticks down an additional 1.5" so road pan clearance on a corvette becomes enought less that speed bumps could potentially be a problem

maybe its because I live where theres lots of dirt roads, or mud dauber wasps ,but every time I put a vette up on the lift with one of those oil pans with the tubes thru the oil pan sump, those tubes are packed solid with mud

SkidZ wrote:Is there a trans fluid "pickup" that would need an extension when going to a deeper pan?

that would seem to be a very logical approach, but it doesn,t seem to be necessary or mandatory as no supplier of the deeper transmission pans Ive order those deep pans from even suggests you need one and if there was a few buck$ to be made selling you one someone would sure be doing it at a premium.
just to make sure IM not giving out bad info, I called two large transmission shops selling those deeper trans pans, both shops confirmed a deeper pick-up was not needed or usually available, as the fluid level remains well above the pickup when the transmission fluid dip stick reads normal levels
I found these (filter extension spacers bellow) at summit racing and called those transmission guys back , pointing out they were for sale, both transmission pan suppliers pointed out that there were internal post supports designed for filter support at the stock depth, and lowering the filter would require cutting the support posts, they re -confirmed its not necessary.
IM inclined to aggree as IVE used the aluminum ribbed 2 qt oil pans with a stock filter and an additional oil cooler with ZERO problems for many years on several different cars making over 450hp or more!
I called a couple buddies, and discussed this as its an interesting question, not one of my freinds has ever used a spacer on the filter but most use the slightly deeper 2 qt additional capacity aluminum oil pans on the transmissions and an oil cooler for thier transmissions, again no problems reported

Thanks. I've got a deep pan sitting on a shelf, but I wasn't sure about the pickup. If I remember correctly, I've seen a pickup extension at Summit, but it doesn't sound like I need one.

routing transmission cooler lines, should be thought thru carefully so engine exhaust or vibration won,t damage the lines, a restriction to trans fluid or oil flow will generally be the part of the connecting lines with the smallest cross sectional area, if you look at most automotive oil or transmission coolers they have AN#6 (3/8")or AN#8 (1/2")connections, so lines significantly larger won,t do much for increasing flow rates
one factor thats frequently over looked is the oil feed and return line internal size and line heat rating,THINK IT THRU, now it should be obvious that fittings tend to have smaller more restrictive holes thru them than the hose internal dimensions of the fittings used with that hose, a fitting designed for 3/8" hose wont allow full 3/8"hose or component oil flow rates, AN-6 is normally considered about equal to 3/8" but thats doesn,t tend to be true, AN-8 size fittings are usually used to get decent flow in a 3/8" oil cooler , if your oil cooler has 3/8" internal passages youll want an AN#8 line size to insure the MINIMUM 3/8" internal passage size is maintained and not restricted by use of the internal passage size of AN#6 fittings

lines should be as large as the connection fittings will allow (generally NPT 3/8", but ideally AN#10,)
and routed so they won,t get burnt, or snagged easily
remember your goal is to provide a steady flow of transmission fluid at about 170F to the transmission, if you run the trans fluid thru the cooler then thru the radiator it will get no cooler than the engine coolant temp which usually runs in the 190f-220f range in most cars, adding a transmission fluid filter is a good idea if you race the car or regularly subject it to hard use.

coolers with aux fans tend to be far more effective

you generally feed the fluid in the bottom and out the top line connection to prevent air trapped in the lines
naturally youll want to route all lines as far from headers as you can to prevent burns on the lines

mounting a transmission cooler

Postby grumpyvette » April 21st, 2011, 6:03 pm

the first mistake many guys make when installing a transmission cooler is buying one before measuring the location they intend to install it at for clearance and the second common mistake is buying one that's either too small to effectively remove heat fast enough to keep the transmission fluid at the ideal 170F -175F range, or too large to install in the intended location.
one factor thats frequently over looked is the oil feed and return line internal size and line heat rating,THINK IT THRU, now it should be obvious that fittings tend to have smaller more restrictive holes thru them than the hose internal dimensions of the fittings used with that hose, a fitting designed for 3/8" hose wont allow full 3/8"hose or component oil flow rates, AN-6 is normally considered about equal to 3/8" but thats doesn,t tend to be true, AN-8 size fittings are usually used to get decent flow in a 3/8" oil cooler , if your oil cooler has 3/8" internal passages youll want an AN#8 line size to insure the MINIMUM 3/8" internal passage size is maintained and not restricted by use of the internal passage size of AN#6 fittings
Image
Image
its bound to be really a P.I.T.A. to find the trans cooler you bought won,t fit or it can,t cool the fluid sufficiently, so do some measuring and research on the flow and cooling capacity of the components you select.
now it should be obvious that a tans cooler with a built in fan will generally cool more efficiently than a simple finned heat transfer unit because the fan can force a far greater volume of air over and thru the fins to absorb and transfer heat to the surrounding air.
the next problem many guys seem to run into is line size, line routing and fittings, for some reason theres a tendency among some guys to always want to install the trans cooler in front of the radiator , while this places it in a good area to be exposed to cool air in most applications the hot air that flows behind the cooler is now expected to cool the radiator, which it obviously can,t do as efficiently as the previous cool air before the trans cooler installation, so your in effect curing one problem by causing a slightly different problem.
its best to locate a trans cooler and its lines and t-stat where it can get its own dedicated supply of cool air for its electric fan,but just as obviously theres limitations in most cars where you can install a cooler due to clearance issues.
on many cars theres room either near the trunk or only near the radiator, so your choices are limited, unless you want to get creative and fabricate a custom trunk floor, duct work or similar custom location , if that's the case expanded or perforated aluminum brackets or protective shield may be a good option

if you have the room there that might be a good option, but remember the size and air flow rates have a huge effect on how effective the trans fluid or oil cooler will be and just (HAVING ONE) doesn,t cure the heat issue, its got to be large enough to effectively transfer the heat to the air flow and be effective at reducing heat, once both the engine and transmission temps are up to operational range, and in many cases that takes a fairly large cooler with an effective fan.


as an example I helped a guy I know ANDY who has a 67 chevy pick-up truck with a 496 BBC engine and TH400 transmission and a 3.54:1 rear gears, too, get his oil cooler working correctly.
because his trucks basically a weekend toy used mostly as a semi race, drag car,and local street hero, that runs mid 11 seconds in the 1/4 when its not breaking drive train components. he found he needed a trans cooler.
He only admitted that,after he burned up his th400 trans clutches , so he installed this oil cooler, at first it barely helped

not wanting to waste that oil coolers capacity ANDY, bought this cooler and plumbed it in serious , both were mounted under the pick-up truck bed , and together they dropped the trans fluid temps during normal operation to about 190F which was easily 25 degrees lower than the previous fluid temps

never one to give up,ANDY finally, pulled one of those two coolers and replaced the smaller one with a larger cooler with a fan,and left the larger non-fan equipped cooler plumbed in series under the truck bed, and wired the fan on the new larger cooler to work as soon as the ignition was powered up, this proved to be effective and last time I saw the truck he stated it cured his trans fluid over heating issues.
not wanting to waste the smaller cooler he moved that to the frame area and plumbed it to use as an engine oil cooler, he stated it helped drop oil temps at least 15F so he was pleased with both upgrades

If I did it again Id select this trans cooler (pictured below) as the larger line size would help reduce flow restriction, its smaller width would make it easier to install,
THATS IMPORTANT!, MEASURE VERY CAREFULLY BEFORE ORDERING
I know several people that ordered trans coolers and found they would not fit into the originally intended location because they failed to correctly measure the intended location space, in ALL three dimensions,and over the whole space, before ordering , I know I failed to measure carefully so I was forced to place it where the spare tires normally mounted

Re: transmission cooler info and derale trans cool pans,

Postby grumpyvette » July 31st, 2013, 12:04 pm

before you go installing an extra deep transmission or engine oil pan on your car its a really good idea to have someone measure the distance from the cars current oil pan or transmission pan to the pavement WITH YOU AND A FRIEND SITTING IN THE CAR..watch the video before you go spending a great deal of time and money swapping to the deeper oil or transmission pans.
trust me your not the first nor will you be the last guy to do that without checking only to find out its an expensive mistake.
adding a transmission cooler and remote located high capacity oil or transmission filter, as a way too cool trans fluid and provide extra volume is frequently a much safer option


WATCH VIDEO...and think about all the speed bumps, concrete curbs, high manhole covers ,bits of road trash, and pot holes that your car travels over in a years time.
Id strongly suggest a 3.5" MINIMUM under the car clearance, between the pavement, headers and other components with you and a friend sitting in the car and a skid plate is certainly not a bad idea.
