Transmission failed on acceleration from stop. Brought to chevrolet dealer who told me "the 1st and 2nd gear came apart internally" and that a complete rebuild was necessary. No prior indications of transmission problems (I.e. Slipping, noise, etc...). Will cost me over $3000 to repair. Searching on line, I found several other owners complaining about the same problem with less that 90000 miles on their vehicles.

Transmission failure, no warning signs. Vehicle felt like it popped out of gear. Truck does nothing in drive, only moves in reverse, 1st, and still does major slipping. Online research has informed me that this is a common issue among this type of truck.
