Trans cooler

Well if the trans fluid is at 250 F... then the rad will 'cool' it LOL.... it's all relative.

My son may add an external cooler up front with a temp bypass on his '65 Cuda. The trans fluid temp is getting up to 225-240F -ish on the interstate with just a 2500 stall TC and with air temps just at 70F. It does have an external cooler in line with the rad cooler, but it is one like this one below and is under the car and too near to one exhaust pipe; not a good installation...
