I put in a 3,000 stall converter into my girlfriend camaro, along with the higher compression motor, and it seems to be heating up big time because of it. What exactly are you supposed to do when you have a high stall converter in a car? Is the factory radiators tranny cooler insufficient? This is a 10 inch converter so it really DOES stall at 3,000 rpms and feels really slushy unless your'e above about 3,200 rpms or so. I'd imagine that builds a bit of heat. Trying to solve an engine over heating problem.......my guess is the tranny fluid may be overly heating up the coolant........but I've heard its usually the opposite that is true.....????

 

You definitely need a trans fluid cooler. When the converter is "slipping", i.e. below its stall speed, it's just like a mechanical clutch that slips; and all the heat that is generated goes into the fluid. YOu stock trans cooler is in the "cool" side of the radiator. SO what happens is that the coolant flows through the rad, gets cooled, and then gets heated back up again before it gets back into the motor, so it's already too hot.

Try a trans cooler, it may or may not solve your problem, but the car needs one regardless.

 

Yep, definatly need a cooler! Like this beauty Supercooler on Ebay (uhhumm.. uhhmmm...)

But anyway, there's two other things that are making heat. More horsepower and more cruise RPM so a bigger radiator may be needed... Start with the lower air deflector, if it's missing get a new one... It really does make a difference. Then maybe a lower temp fan switch could help....

Good luck..

 

Get a race supercooler by B&M. They are only 60 bux plus hose and fittings at summit. I just got one for my tranny and Im running a TCI super street fighter that stalls between 3400-3600

 

Any converter with a stall higher than stock should have an external cooler installed. Heat is the biggest killer of trannys. Without a tranny temp gauge you have no way of telling just how hot the tranny fluid is getting. Above 230* and the seals start cooking. The tranny temp should be around the same temp as the engine. 180-200* is prefered.

My 8" converter in the race car generates an enormous amount of heat. I have a huge cooler in front of the rad and after a 1/4 mile pass the temp is up to 220*. The converter also stalls at 5000+ rpm.
