Unplugging the TCCM isn’t a fantastic plan since it truly doesn’t attain anything at all. Should you be caught in 4WD (which it seems like that you are), unplugging the TCCM won't get you back again to 2WD. However, I don’t need to tell you to carry on to drive the automobile with out figuring out more information and facts — you could have a problem Together with the gears/forks during the TC which may not allow the encoder motor to physically swap modes — naturally, driving the motor vehicle Within this issue would only trigger greater problems.

I have found I could possibly get it from 4HI in a single of two approaches. If I park whilst trapped in 4HI and depart the vehicle for some time, when started 4HI will flash and it reverts again to 2HI. OR If I put the truck in neutral, push 4LO (it goes into 4LO) then press 2HI, There is certainly clunk and it goes back into 2HI.

I'm able to explain it a little more to suit your needs nevertheless! The “kick panel” is located within the passengers facet, entrance seat, ideal exactly where the travellers ideal foot would rest. In case you’re sitting down while in the travellers seat, “swing” your correct foot from still left to correct while keeping your heel on the floor.

Amount 7 continues to be the culpret in two of the blazers I've labored on its hardned steel so will not try and make just one out of any washer it is going to fail. GM sells this washer in the things they call a washer this kit it features 7, 20, and 24. If any one has this problem its an easy take care of and you also dont even have to eliminate the diff, just the axle tube, but youll have to eliminate the halfshaft 1st this correct took me just over an hour or so to accomplish.

Raymond Dunne suggests: January seven, 2008 at ten:27 am Effectively after alot of time on my 2001 Jimmy 4wd system I'm still stumped. Started off using a clicking sounds from front close so I checked vacuum actuator and it’s undertaking it job since I loosened up the cable. Truck won't go into 2hi or 4lo so I pulled the Regulate module and checked wiring. Big orange wire on electricity connector was included in corrosion and 1 wire on 32 pin connector was corroded.

You may also unplug the TCCM and faucet on the encoder module to find out if it may be caught (a heat garage wouldn’t harm possibly!) — depart the TCCM unplugged for at least two minutes, then plug it again in. Then, convert The main element on to off 5 periods, then to on and try it.

I hope this thread remains alive. Anyway, I have difficulty receiving from 4HI. I've read through all of this dialogue and Tried out a lot of things. I changed the vacuum turn on the transfer circumstance(mine was trapped). Then I checked all vacuum traces(some have been cracked and I changed). Pulled the encoder motor and cleaned it/took aside and re greased/sealed.

3) the encoder motor/module is terrible. This is the module/motor which is mounted on to the transfer scenario, who’s career it is to physically move the gears from the transfer situation to put the TC into the assorted modes (2Hi, 4Hi, 4Lo).
