Great Lakes Warranty. When I bought the VX sight unseen, the deal I made with the dealership is it had to have a warranty. They said they gave it to me at cost. It was like $512. 1 year, unlimited mileage drivetrain. $100 deductible, have to change oil every 3K miles, and do all recommended dealer maintenance. You also had to put at least 500 miles before filing a claim, which was fine for me since I drove it about 800 miles home. It does not cover AC, but does cover CVs, and everything under the hood/tranny/diffs/transfer case and so on.
I am happy.
As for the maintenance, I didn't know about all that when I had it done, I had only owned it for a month or so at that point. Seems weird that we have that problem since it is a standard GM tranny? I do know pepboys would not service it. They said they would do anything but the tranny since there was no dipstick.
Oh well, I guess I am lucky that I am getting a new one.
