Need help again!!!
Let me start with sorry but I need help again. Every tune that I try to put in my LB7 truck screws up the trans. It don't limp it, the first tune I put in made it sorta go into neutral when it down shifted from second to first. ONLY SOMETIMES. The second and third tunes work great but after 5 or 10 miles it down shifts to third and trips a trouble code on the TCM P0735. It says wrong 5th gear ratio. What am I missing. I am posting my stock tune and mod. tune if anyone can help that would be great. I WILL FIGURE THIS EFI OUT even if it kills me and my truck..
