Quick question. I have the 4T65E-HD, and I was wondering if there are any issues with heat on these tranny'*. Also, I found 2 different 180* stats for my car - a standard type and then a reverse poppet. Which type to I get? I'm sure that they do the same thing, but do they do it in the same way?
I wanted to comment on going with a stat that was too cold. I had a 160* stat in my '94 Jeep (it was a turd and I was experimenting), and I always got a "coolant too low" code. Plus, in traffic it would overheat like a bitc*!
I never changed it, but I know from experience that you don't want to go too cold. I think that 15* is fine, but 35* is WAY too much of a change without programming.
