Buick Lucerne Code P2761 And P0748

2006 Buick Lucerne. Engine size = 3.8 v6 Dash lights service engine soon codes p2761, p0748.

Question:
I have the service engine soon light on the dash of my 2006 Buick Lucerne. I had it scanned and the codes come up p2761, and p0748. Also it does not start sometimes. Can you please help with these problems, i absolutely love this car. Thanks you.

ANSWER:

Thank you for the tip/donation. These codes are transmission related. There is a common wiring problem that can cause intermittent no crank or start and these transmission codes. There is an area under the hood where a main engine harness rubs through and damages several different wires. This would be the first place to look.

I will send a pic of the area shortly. Let me know if you do find some damaged wires and need help with the repair. If wires look OK, then we can check a few other things.
