The main issue is its not changing out its hung in maybe 2nd gear and when you put it in R D or P it jerks really hard

You put a transmission module in this. Was the problem present before you replaced the module? Did you program the TCM the way it needs to be programmed?

Wouldn't shift out before I put it on but the brake light didn't stay on and the brake service didn't say that

Sorry TCM

So how do I program it
Expert:  Jerry Newton replied 2 years ago.
It requires dealer equipment. You cannot plug and play a transmission module, they come out of the box blank and must be programmed with software specific to your truck. You'll have to take it to the dealer and have it programmed.
