Issue with Transmission

So I was working on my cluster board and removing the green film so my dash lights could be white instead of the green and I don't know if I didn't hook something back up right or something but now my truck is all messed up. The speedometer is no longer working and my transmission feels like it is failing. It is shifting hard and jolting forward anytime the gear changes and it is almost like it is guessing where to shift. It's an automatic transmission and I'm just hoping that I messed up with the reinstalling and that I don't need to go out and buy a new transmission... Please help!

Also my OD light is flashing...

The flashing light means that codes have been stored. Having these codes would make this much easier.

If you messed with the gauge cluster, either you didn't plug the PSOM in correctly, or you've disturbed the wiring/grounding some how. This is assuming you had zero issues like you described before.

Speed sensor wiring got compromised. That will cause your speedometer to be inop, as well as any speed sensor signal needed for proper transmission operation.
