My T/C light is on and want go off. What can the problem be?

Both of those codes could relate to wiring/bad connection issues. Does the shop you are taking this to have the capability to communicate with the ABS computer, or does their equipment only support OBD-II protocol? Why was the EBCM (ABS computer) replaced in the first place? Without looking at the car, I can't say for sure, but an internal transmission problem doesn't sound likely from the information I have.

take to tranny specialist. could be as simple as dirty connection. could mean the torque conv. failing. tranny tech. will know. review when tranny last serviced. it may just be due.
