problem #1

May 022010

Suburban 4WD

  • 74,000 miles
Driving in a 55mph zone, vehicle transmission failed. It appeared that the auto 4X4 switch was changing. Placed vehicle back in 2 wheel drive, driving 55mph, transmission failed again. When switch was set in auto 4X4, the vehicle ran in 4 wheel drive but no other settings worked properly. I have had multiple diagnosis attempts. There are bulletins on the auto 4X4 actuator and on a transfer case motor sensor.
