I have a RMVB TH400. It has a transbrake and was just recently rebuilt with all new clutches, sprags etc etc. The xmsn has run hot since putting it in. It has a B&M deep pan it also has a B&M plate and bar cooler that is mounted infront of the radiator now. It is fed thru stainless steel braided lines. I have a xmsn tempature gauge that is in the pan. The converter is a FTI unit that was custom spec'd for my build. Car is a forged 370, tc78 turbo and a MWC rear with a 3.00 gear and a 28" tire.
Car sees 200+ within ten minutes of driving. I have had the ccooler in two other places and it does the same thing. I just installed a 9" fan on it tonight but haven't wired it up yet.
Why is this car getting so hot? With all of the provisions that i have for it cooling it just doesn't want to stay cool. The converter is pretty loose on the other hand.

Believe me when I say, that may not be a big enough cooler for street driving....
Derale sells a double pass cooler with a fan on it already. That one I have had good luck with. We wire up the fan, so that when the car's IGN is on the fan is running too, fwiw.
Usually enough to keep stuff under 200 even with extended periods of driving, and if that isn't enough for you, look at your local area junk yard for a diesel pickup... you can get a cooler out of that, and as long as you can get it in the car in front of the radiator, you will NEVER have another problem. They are a bit overkill... but work. Usually hold a quart to 2 quarts worth of fluid too, fwiw.

Dude mine used to run hot until I relocated the cooler away from my a/c condenser and radiator. I used a B & M Trans Cooler with these dimensions:
Racing Transmission Cooler Only
29,200 GVW
29,200 BTU
11'' x 11'' x 1-1/2''
No Kit Available
130-70274
I put my Tran cooler on the front left side of the FMIC opening. It has about 4 inches between it and the FMIC piping and sticks out a bit to catch air. I would rather not have it there but with that front-end that was the only place I could find to put it. Now it is nice and cool around 180* to 190* on a hot day in FL.

^^ wow that is "f" up..in theory open like that with a fan seems that it should be quite cool!! however..i would bet at a stand still the fan does what it should,..is it possible that while moving faster than the fan speed that its actually deflecting air away?? maybe like a turbulance of a sort?..im certainly interested on that..

My setup is different than the OP though. My PTC converter is a loose 8" 5500 stall built for max-effort NA.
