One of the primary reasons why I bought my Max/Allison combo was the transmission.
I may have posted it here before, but I completely blew the transmission out of the bottom of my 2002 Avalanche with 38,000 miles on it - and 19 months of ownership. If I hadn't purchased an extended warranty, I'd have been out $1500 for the repair (no, they did not replace it as I'd hoped they would).
Over the past month or so, the trans in the Avalanche began to slip when accelerating from a standing start, and I just didn't feel like screwing with it again, so out it went... and in came the '04 Silverado.
I'll very likely purchase an extended warranty to cover the transmission for the same 100K miles that the engine is warrantied for. I've been told that it takes $7000 to replace the trans (can that be true?), so it seems like cheap insurance to pay $860 for the additional coverage on the transmission, as well as the rest of the truck.
I love this truck... I just want to put some bigger rubber under it and then drive it til the cows come home...
