I have a 2005 Z71 Tahoe. Sometimes it will kick out of gear while driving down the road. So I pull over and you can hear a light grinding noise from the transmission. Go to put it in Park and it grinds while going through reverse (only took one time for me to not do this again). The way to get it going again is to put it in neutral put it in 4WD then back to 2WD and all is fine. This only seems to happen sometimes when going around left hand corners. I let off the gas to go around the corner and when I go to get back on the gas it has kicked out of gear. Thanks in advance for the help.
