Hi! My 2006 Avalanche will no longer shift into 4wd low. All of the other modes work fine. I put the transmission in neutral while the truck is in one of the other settings. I allow the truck to roll very slowly down the drive and press 4wd low. The light flashes and the normal clunking sounds forward and rear can be heard. Then the light quits flashing and it returns to whatever mode it had been in before.
I'm not a mechanic. I just would like to know if this is a potential transmission starting to go bad, or if it sounds like something related only to 4wd low?
Dumb it down for me.
