It shift into 4th with the tech 2 when I take it on a test drive I watch it shit up to 3 gear then I shift up with the tech 2 it going up a gear for sure cause the engine is not reving high and I’m doing 50mph in a step van
The truck has no codes at all now voltage is 13 volts. Batteries needed charged Won’t go past 3rd grear on its own using the tech 2 shifted through all the gear no problem
I messed around with the truck today it seems the truck shifts upto 3 gear but does not shift beyond that. I had the tech 2 hooked up and shifted through the unit with now problems through all the gears just won’t do by itself
