transmission dead after 44k miles
By jms20 on


2008 GMC Sierra 1500 SLE1 2dr Regular Cab 4WD 6.5 ft. SB (4.8L 8cyl 4A)


I bought this truck new and it has been generally fine.
Unfortunately the transmission self-destructed 1 month out of the 5 year warranty.
I do mostly city driving and rarely tow.
The dealer tried to repair it but apparently it was so bad they gave up and put in a rebuilt one.
Very disappointed given I've only driven it 40k miles.
The dealer was able to get some of it covered by GMC at least but I felt like they should have covered it all since the problem started before the 5yr end date.
