2001 HD wont shift out of 4wd
I have a 2001 Chevy HD and been having trouble getting it out of 4wd. You can here it go into 4wd from 2wd. Then you go to put into 2wd and you can't here it change back. You drive it and it is still in 4wd. If I put it in reverse and push 2wd it will disengage from 4wd back to 2wd. Does this sound like a switch problem or something else. The lights on the switches will change when you push them but it will stay in 4wd.

Re: 2001 HD wont shift out of 4wd
The trucks do have switch problems. There is an updated switch for the trucks. Sounds like the problem a custmer had with his truck and it was the switch.

Original switches a major piece of JUNK---you need to replace the switch.

Re: 2001 HD wont shift out of 4wd
Is there a way to get it out of 4wd if you push the 2wd button and it wont change into 2wd?

It does sound like a switch problem. Mine is giving me issues too, but I don't use 4wd enough to have changed it yet.

Re: 2001 HD wont shift out of 4wd
I think GM superseeded the part number. The TSB is kinda old. So any switch you get now is the new switch
