Since the diff is part of the power train, I think you could make an argument that it's covered by the 5/100K warranty unless it's specifically excluded. Check your warranty book for the specific language.

cidsamuth Welcome to the fourm
The users manual will provide the info you need...
The rear diff gasket should be pretty generic but even getting it from the dealer should not be very costly and you'll know your getting the exact right one ( bring your VIN in with you)
I would question why you would want to service the tranny so soon particularly if you don't do a lot of off-roading or towing.... you should be good for 100k miles...
As for the fluids, I would use the synthetics but also check to see which cases will need additives in addition to the fluids...

Change automatic transmission fluid and filter
if the vehicle is mainly driven under one or
more of these conditions:
− In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C) or
higher.
− In hilly or mountainous terrain.
− When doing frequent trailer towing.
− Uses such as found in taxi, police, or delivery
service.
Otherwise its 100K, I did ask my service adviser at my local dealership if I should have my transmission serviced since I do some light towing of a camper trailer... given the weight of my trailer and the limited amount of towing he recommend I wait till 100K...
They could have made money off of me...
It comes down to personal choice....

published materials will say 50k for gm but as anything with an automobile its a matter of opinion or who you want to believe
I base all my opinions off my personal experiences beings I've been in shops longer than I've been driving. To each their own

Well, some great info on this thread, and it has helped much.
I called the dealership, and the rear diff leak IS covered under the powertrain. While there, I think we will just pay them the $200 for a trans flush -- especially since a fluid/filter change by me doesn't get but half the fluid out anyway.
They want another $100 for the transfer case and $100 for the front axle -- so I'll probably circle back and do those myself, since they are relatively easy.
