Hello pros, I have a gmc 2500hd with Allison trans. Push button 4wd. I can be driving along running perfect at any speed just putting along and all the sudden, it pops out of gear and makes a "zzzzzzz" sound from I think the transfer case. I let off the gas and it goes back in gear smooth as it can be. It does it every few miles. Anyone seen this problem? I changed the fluid. It was low. Still does it. I have tried unplugging the shift motor and no help.
have the same problem?
