Engine Performance problem
2004 Chevy Tahoe V8 Four Wheel Drive Automatic 88900 miles
When I try to shift my truck into reverse, it makes a loud grinding noise in the back while in 2wheel low. To go in reverse, I have to put the truck into 4 wheel low, reverse, then put it back into 2 wheel. I have no problems in drive but the engine is shifting pretty hard. Transfer case?
Oh and it's a z71
