Hi jiggalla,I concur with the above, p0607+p0884 means TCM usually has to be replaced. I bought mine and already had the engine harness replaced hoping that would fix the issue, replaced the clutch and clutch gasket (it was leaking through the bell housing causing severe slippage) and now 3 tanks after all that, BAM CEL, those codes and its going into the shop AGAIN for a new TCM and possibly PCM. I've spent so much on this car, I wish I had done the research into the recalls before buying it and would have bought a different car.
When's your appointment? Please let me know, along with your mileage.
