Expert: CAJUNSC/RAMBLER390 Date: 12/28/2007 Subject: GMC Sierra 2002 Reverse issue
Question My GMC Sierra 2002 1500 4x4 reverse went out when backing into my driveway in 4 wheel drive. Sounds like it's in neutral, does not work in 2 wheel drive now either. Did something snap, is there an easy fix?
Answer Hi
Is the transfer case motor moving? Can you hear it clunking?
If so You probabally have an internal transmission failure (Reaction shell stripped out?)
If you cannot hear the motor turning the T. case, it MAY be stuck in nuetral and if the Tcase is then there will be NO movement of the truck.
Please if you need more help, follow post back
