First post for a newbie so here it goes. Hopefully Roadie will see this or anyone else with ideas or thoughts please reply. Just bought an 03 TB a couple months ago for a commuter ride to work, I work at a mine at 8600' elev and definitely need 4WD in the winter. Here is what it does, it will shift into all the different positions of the transfer case properly without any troubles, in A4WD the fronts kick in when sensing rear slip properly and seems to work correctly. When I put it in 4HI or 4LO on slick conditions it will spin the rear tires and not seem to have any pulling from the front tires. If I put it on jack stands and put in 4HI or 4LO the fronts will spin when in gear(at idle) but I can physically stop the fronts by wedging a block under the one side to stop it and grabbing the other front spinning tire with my hands and stop it(just like the wet clutch in the transfer case is now slipping). Should the TCCM adjust for wet clutch wear in 4HI and 4LO like it does on A4WD? If not is there anyway to adjust the engagement pressure on the wet clutch when in 4HI or 4LO so that it locks in solidly like I think it should? I hate to replace a transfer case if it is not needed, but I would prefer to use 4HI on the snowy mountain roads I travel over using A4WD. Thank you Roadie for all your help to this point getting things figured out. Thanks for any help all of you can give me with this.
