I have a 1991 Chevy dually with a 454/4L80E and the tranny is done. Been looking at some research online and I'd like the get the best shop out here to do it. Like the warranty of Jasper and GM for their remans at 3 years and or 100K miles but I'd prefer a local guy who did better quality and something specific for towing. We aren't towing much: a camper, a 20 boat, an light enclosed trailer with dirt bikes, not all at the same time.
I want a guy who does it right by replacing everything including the electronics.
