4l60e cooling question

[burpin94]

What has the biggest bang for the buck when it comes to reducing temps? Aftermarket cooler like b&m 70266 or deep pan?

Bigger cooler for sure. Tru-Cool M7B is the cheapest and largest I'm aware of that will fit without relocating the horn and some other things.

Ok so I took a look and the cooler has already been upgraded. It's 8" x 11". I'm wondering if the tranny was already rebuilt. And hopefully upgraded. I wasn't having any temp issues I know of. I just want to be able to tow my little boat. I thought reducing temps would be a good thing.
