Transmission temp over 210F at times. Outside temp. 85F. Would the diesel do any better?
(Off topic: Do I need an aftermarket tranny cooler?)
I just towed my 1983 S-10 pick-up @ 300 miles. I think it weighs @ 3000 pounds. Got 21mpg. No issues and didn't need to use tow/haul. Pretty hot that day. Trans temp was @ 190-195. BTW - I got 31 mpg coming home empty.

Rather nerve racking to have to take my truck in immediately after putting in the tune. I put it back to stock on Monday and have a service appointment for Thursday. I have been working with Duramax tuner on the issue. They say it's very isolated. The truck did run like much better for the 20 miles I drove it before it falling limp.
