Hello, my car is kicking out P1757. I have done some reading and it looks like a bad trace on the TCM is a common culprit. I have removed the TCM from the Valve Body, but I don't see any way of opening it to check the traces without breaking it. All Solenoids meter out fine- I'm pretty sure the problem is the TCM.

Have any of your swapped out the TCM and had success with getting this fixed? Also was there any reprogramming needed ?
