thanks man. i am gonna get new MAF sensor tomorrow and intake air temp sensor. then i am gonna hook it all up again and see what happens.. I was also told (GM mechanic) and maybe this is what you were telling me but the MAF can cause false trans codes to pop up but the vehicle will have real rough idle cause it was a bad MAF...Exactly what mine is doing, so wish me luck.

Another new thread about this? It really would be best to keep it all together. Don't worry, I'll merge them back to one.

Did you trace out the wires as I had suggested previously?

Are you Positive about the P1100 and the P0700 codes? I have been told a thousand times its Transmission codes installed from the factory, like "ghost codes"...Just wondering
