Three problems related to equipment have been reported for the 2002 GMC T-series. The most recently reported issues are listed below.
At 68,994 miles my truck lost 2nd gear, drive, overdrive and reverse. A new reaction shell was installed. At 90,027 miles and 360 days later the same problem occurred and a beast heavy duty reaction shell was available and installed.
The driver side seat belt did not lock. It allowed me to hit the windshield.
Windshield wipers recall from 1994 on up to 1996 I think but none prior to that. This is a wide problem and I know of 4 other people that have this same issue with the wiper module.
