hey just bought a 06 zephyr and did not notice this till today when i actually turned the stereo down. From a stand still till 2nd gear, the tranny whistlehums. Is that normal? checked fluidlevel and condition and it looked ok. O and what kind of fluid goes in this trans? any help is appreciated. just turned 22k on the odo

I had one for 40000 miles. No hum from tranny. It should still be under warranty so take it in and do a test drive with a service advisor or better yet a technician and make sure they hear it. Let us know how it goes!
