Does a trans cooler really help the trans run cooler.If u know by how many degrees difrence.4l60e Trans.

 

Yes it helps the life of the trans, especially if you drag.

 

A tranny cooler is THE best thing you can do to help it last.
My cars Ebrake handle would get seriously hot before the tranny cooler (the metal part of the Ebrake handle) especially in the summer time.
After putting in a B&M cooler its always cool to the touch.
I would put one in regardless of whether your going with a stall or not but its imperative in my opinion to put one in with a higher stall converter.

 

Agreed, I would love to see one on an unmodified trans, but the second you put a stall in, it's pretty much a requirement
