Re: noise ??

What year and model GP do you have? Other than the whining sound any other problems like harsh or poor shifting?

Re: noise ??

Its really hard to say. If it is a mechanical whine and not a whine caused by bad or high line pressure you may be OK.

Checkout this thread. He installed a ZZP re-programmed PCM module and wound up getting whining and harsh shifting.

If you decide to get a re-programmed PCM module I would recommend using the DHP. How bad is the whining and under what circumstances do you hear it?
