Default TransGo boost valve

This valve raises trans line pressure. I bought one for an 4L60E(truck). Anyone try this valve before? Should I add a trans cooler or cooler pan with it?

A boost valve itself shouldn't necessitate a transmission cooler, but an additional tranny cooler is always a good idea. I have larger boost valves in both of my 700R4.

BTW what size boost valve is it?

On the 4l60E you can also raise line pressure by programming the PCM. Don't do both. :chevy

OK, I just want to make sure your not putting in a .471 which every vette should already have.
