So I'm working on my old truck it has a 351w and an e4od. I have a Tru cool trans cooler new in box that I picked up years ago.
From what I can tell it's to small for my truck 4x11 inch 7500 btu.

Does anyone think it's even worth installing such a small cooler?

I don't pull a lot but I do go up logging roads at slow speed tends to warm things up.
Thanks.

 

I'd say it's too small to even mess with. The factory trans cooler on my 95 302 4r70w is about 10 x 10 and what would seem to be 2 cores in thickness.

 

Okay thanks. I'll order a larger one.
