Nope, no "u" codes that he told me about. No ABS either, just the (T/C) light. When the light comes on, after stopping at a light or stop sign, it will shift hard from first to second and fine through the other gears. If I turn the engine off and back on the light goes out and will stay off for a while and it shifts fine. Even when I turn the engine off while at speed. I'm very careful when I do that. What do you think about what he said about when I replaced the battery and it threw C0561 "System disabled info: stored invalid serial data"? He suggested that was the cause of the Service traction light is from. I've downloaded the app to my phone and ordered the same B/T adapter in the picture you provided. Should be here Monday. I have 117,000 on the engine and don't remember changing the plugs and bought some to replace them. He also said that they wouldn't clear the codes. I have a reader (Autozone model) that shows and will clear the P0171 code but it will come back after a few miles, mine says there is 2 codes but will only show the P0171 code. Today when I cleared the code and drove it, the CEL and the traction off/service traction light came on at the same time. Autozone suggested the check the vacuum lines for leaks but I don't have a clue where to find all of them. Would you happen to have a diagram of the vacuum hoses? Thanks for the reply. Willie.
