Odd noise on cold down shifts.
Hi guys. I have a second 2007 GL 450 that I just picked up. I noticed that when I start it in the morning it's totally quiet (normal noises). As I drive it to the end of the block and am braking the last two downshifts sound loud. Buzzing, whining, almost grinding noise. It continues as I pull away for a few seconds, then never comes back after it warms up. The dealer where I purchased it claims it's just the alternator . I have a 15 day warranty and would hate for it to be the trans that they're skirting repair on. Anyone had this before? I'll try to post a vid.

a well worn front diff will make that noise- sounds like a buzzing/ grinding/ groaning on low speed deceleration. it goes away very quickly too once the diff is a bit warmed up
not saying this is definitely the culprit, but most high mileage early x164s have it... and it is not an indication of pending diff failure.
