Good info guys, thanks.

Willys36 - I have a non-smog motor so I guess running it through the rad is cool ... I sure don't want to add any electric fans if I can avoid it -- I don't want the noise!

One thing we are overlooking when talking about "200F" radiator temperatures in relation to transmissions that don't like temperatures over 180F is that the tranny coolers are placed in the bottom pan of the radiator. There it sees the coolest water in the system rather than the temperature gauge which is measuring the hottest water right out of the top of the engine. At that point in the system the temp should be about perfect to cool/heat the tranny to optimal operating temp.

cooler pan

Consider that the engineers planned on the fluid to be able to dissipate the heat through the loolant in the radiator. That doesn't include the heat lost on the about 8' of tubing that it travels through to get to the radiator and back. To be safe, you need a cooler that will allow good air flow to cool the fluid quickly. I have seen coolers that have fans to pull or push air through them, for cramped spaces. I would feel relatively comfortable with something like that. The further away from the trans and exhaust, the better. Just a small "radiator" type(tube with minimal fins around it) mounted to the frame where it cannot get full air flow, is asking for trouble. Even with a deeper pan, it will likely get considerably hotter than it should. You have to consider that this fluid is under high pressure and therefore moving quickly through the cooler. There used to be deep pans with tubes in the bottom of them for air to go through to help cool. Those pans helped with some vehicles that had repeat trans problems. I have not seen them for sometime, and am actually looking for one for a Ford C-4.

I have seen lot's of this type of transmission pan.. and 95% of them leaked.. and 99.9% of them that I pulled were on a burned up trany

in my years in a transmission shop.. I would NEVER run one if I had any choice at all...

I haven't heard it said yet...

Stacked plate coolers are more efficient then the normal tube & fin type coolers. They also have less pressure drop thru them. I had a friend that had problems with his 4x4 on a tough trail. His trans got up to 260F. He had one of the tube & fin coolers that came with a fan on it. He went out the next week and bought a stacked plate cooler!

trans coolers

check out this website.they tell you all
about trans cooling and life expectancy.
www.transmissionhead.com
the lines run from the trans to the radiator
then out to the cooler and then back to the trans.

trans cooling

I would just like to add that synthetic trans fluid such as amsoil synthetic trans fluid is capable of lowerind trans fluid temp. from 20 to 50 degrees on it's own dependind on the application.This is an extra add on that is bound tohelp lower the tempa fair amount dependind on the application.They make a racing trans fluid as well for us hotrodders.I use it & sell in & am pleased with the results.any comments?BOB

THe company I work has tested various fluids / additives that claim to lower oil temps with no other changes.

We have never been able to verify the claims

I just did this cooler came from jegs double outlets on one end 4 mounting holes used russell fittings and stainless steel hose . ran hose from left side of rad to 1 inlet of cooler tied in other outlet of cooler to trans tied in, other outlet of trans went bvack to other side of rad, clamped everything to frame. nice and neat . robert seeya dennisakers@itlnet.net
