Q: truck pops out of reverse when gas is applied and make a horrid grinding noise on 1996 Chevrolet Suburban 1500

truck pops out of gear and makes a horrid grinding noise if gas is applied when in reverse. Does not do this in forward gears at all. It will idle backwards. This is an automatic trannie.
