    So, when I bought my 02 GP GT last year at 89k mi the original tranny crapped out shortly after. It was replaced (at no cost to me) with a used transmission from a junk yard. Now...the old trans was always a little " off " from day one when I bought the car so I've nothing to compare to in terms of " proper operation " for the 4T65e. The transmission they put in seems perfectly fine and has no noticeable issues. Shifts smoothly when accelerating threw all gears, and downshifts aren't even noticeable. Just as it should be, right...Now, here is my question...This transmission has a very slight high pitched whistle only when accelerating. And I mean slight...other people don't notice, but I know my car and hear it very clearly. I heard it as soon as I got on the gas for the first time after picking it up from the shop. And I've driven at least 13k on this new (used) tranny in just under a year w/no problem. The original one it replaced made no such noise, but had many issues.

    Is this normal?

    Thanks for any input.
