I know this is going to sound like a syupid question but,
I have a th350 tranny and I am putting in a tranny cooler.
I need to know which line ( the upper or the lower ) is the pressure side? This is going in my 81 camaro. Any help would be greatly appreciated.

Thanks.
SJ

The lower line is OUT

The upper line is IN

Hope this helps.

when i put a cooler in, i leave the top line hooked to the radiator, so it gets initial cooling there and splice the bottom line to run through the external cooler on its way back to tranny.
