Truck has cam, headers, tvs1900 Tranny has never shifted the same since mods. I found a copy of the original file and pulled the current.
Can some one help? Is there that much difference between the two for the transmission? Should the original tranny files be copied over in to the current? If so, how is that done? Simply highlight, copy paste?
Note.... it shifts hard and the torque converter doesn't seem to be locking up.
