To make a long story short.... I've basically had transmission issues since I first got my truck (new 2010 6.2). Harsh 2-1 downshift and odd 1-2-3 up shifting. I got a Hennessey programmer (didn't know any better at the time) around 40,*** miles to potentially solve the shifting issue... only made it worse. Had my computer flashed, only temporarily fixed the problem. Went with a 5* tune and told them the issues I was having, they adjusted the shift pressures and it fixed everything.... for a week. I've been to two dealerships, AAMCO, and had the computer dealer flashed over a handful of times... I'm now close to 70,000 miles and the truck just isn't enjoyable to drive anymore. Rebuilding the trans my only option? Anyone else had this problem? I'm close, very close to selling my baby
