If you Put your left hand on the tcase shifter, right hand on the dash, shift all your weight to the left hand, the shifter will move a little. With continued jerking cussing and violence it might move into N if your lucky it will go to low. Once your in it works fine, and its not much trouble to switch back to N or H. Any thoughts? CDL doesn't work btw. There isn't any physical obstruction on the lever that's noticeable from the underside. Thanks guys.
 
Tried park, neutral, and the rest of the options on the trans. One thing that just came to mind; I sometimes have trouble removing the key after select park and turn the engine off, but this is remedied by turning the key back on then cycling the shift selector back to drive then back to park. It usually rolls forward a few feet after I return it to park, like it was stuck in a gear and then released.
 
When was the last time you checked the gear oil in your transfer case or your transmission fluid?

Trans in neutral is the proper method, any other gear can/will load the gears making shifting hard/impossible. If still stiff, it could be stiff shifter/linkage, lube needed, likely from seldom being used?
 
Go to a big empty parking lot or field. Put the vehicle in neutral and let it roll a couple of feet to completely unload everything. Put the e-brake on. Cycle between H and L ten times or so and see if that helps. If you put the transfer case in neutral, the vehicle will roll even in park.
 
Search on transfer case shifter.
Very common for the pivot point in the shifter itself to become corroded. All linkage is external to the transfer case. Pull 1 cotter pin and the linkage should move freeley on the transfer case end. If not then the problem is internal. If it moves without issue then the problem is the shifter. THey can be removed and rebuilt with a little effort.
 
Thanks guys. Now I've got some angles to work at.

Crawl under and look at the linkages. Possible rust and not lubrication. Spray with silicone spray and trying again...

I know, I am in the NE :cheers:
 
Took the tunnel cover off last night; only broke off about half the bolts! The shift tower is the culprit. Looked pretty bad. After I detached the linkage, I could shift the case with minimal pressure.
 
You should be able to drive out the pin that holds the pivot assembly together. Once its apart it makes it easy to clean up. I made sure to heavily coat the pieces and pack the bottom of the assembly with moly grease before mounting it back onto the transmission. Has been smooth shifting for the last 7 or so years.
 
2014 168k. Winter rain snow.. sits outside. Incredible difficulty moving shifter. Gets better with more driving/shifting. More common in winters. Seems like water getting in somewhere? Anybody found solution?

This is the 80 Series forum. Might have better luck in the 200 Forum. Most of our stuff is mechanical and yours is all fancy hydraulics and electric wizardry.
