Not to hijack, but I just did the first 4x4 launch on the new setup in my truck. The trans is a built 4r100. But it made a loud bang and super hard shift and attempted to shift into OD. Now it wont shift into overdrive, and the fluid smells burnt. Any ideas?

Was thinking more along the lines of having them diagnose the problem for you.

You do understand that there is more to diagnosis than hooking up a scanner right?

Speedometer bouncing around at all? An issue with the vss will cause this issue. Seen it more than a few times. Won't set any code. Hook a pressure gauge up and see what is happening hydraulically and the kind of pressure you have.

generally when the VSS goes its blinks OD and you loose ABS... pull your VSS from the rear end and check for metal shavings. mine had some from the LS that collected to the magnet and caused it to read wrong.
