We just changed out the transmission and the check engine light came on. Later the car started stalling and kind of jerking like it wanted to turn off. We plugged it up to the computer and it said it was the knock sensor module.

Hello, did you find out what the problem was? It's hard to believe the module was bad, did you find there was a problem with the wiring after the transmission replacement?
