new found diagnosis

Recommended Posts

After contacting GM, the ticking rapping noise coming from my transmission was a faulty oil pump. Supposedly there is 3 of them all together. The noise was only when the car was warm. A dealer did the repair for me but im pretty sure you can just remove the pan and do it. Hope this helps if anyone needs to know.

Cool I am glad you got it fixed. Droger03 had a whine and figured out it was his pump and he replaced it himself here are two interesting threads regarding the tranny pump
