1997 Chevy Suburban V8 Four Wheel Drive Automatic 150000 miles
Need to know what would cause it to shift from 2 wheel drive to 4 Hi to 4Lo by its self going down the highway at 60 mph. It made big clunck and then would not accelerate. Pulled it off the side of road and put it in park and made horrable grinding sound. Waited about 10 min. And started again pushed 2 wheel drive and another big clunck then could go. Was not wanting to shift right from 1 to 2 would really bog down. Parked untill can figure out problem. Help is the only family vehicle.
have the same problem?
