Transfer case shifting trouble

I installed a BL and MML about 2 months ago and I am having trouble with the Tcase staying in Low. It shifted good when I first put it together but now it's not wanting to shift good. I installed a Transfer case shifter drop bracket when I did the BL and was wondering if this may be the problem. I may just need to adjust the linkages but I got under it and looked and tried to adjust them but by myself I couldn't get anything to adjust or even figure out which way I needed to adjust them. Any help would be appreciated!!

try having someone sit in the drivers seat and move the shifter while your are adjusting it. this way you can know how much you will need to adjust either way. this worked for me when i put mine in...

When i installed my 2" lift i noticed the stock shifter bracket rubs the end of one of the links and i didn't like that (it looked like a cause for shifting problems) so i removed the rubber bushings on the stock transfer case linkage bracket (the one that bolts on with 4 screws inside the tub) which gave me about 1/4" of clearance which was perfect. I'd highly recommend doing that to any one that has issues shifting after the body lift to give you some clearance there. So pretty much lay under there and have some one shift so you can see if its rubbing anything and if it is than remove the stock bushings and install a big washer on top of that and tighten it like a mofo and you should be good.

As to adjusting goes put it in 2wd and the shifter all the way to the front (have some one hold it down) and tighten it. You can move the links your self from under the truck too.. just takes some extra force.

Others will recommend shifting to 4Lo and adjusting it that way but if you cant shift to it than i guess that wont work really well

BTW MAKE SURE YOUR RIG IS IN NEUTRAL WITH THE HAND BRAKE PULLED AND THE TIRES CHUCKED WHILE ADJUSTING!!!

I am not sufficiently knowledgeable to insert or upload the illustration for the t-case shifter. Consequently, I will talk about the issue. There is a 8-10" or so rod that attaches to the bracket - which is itself attached to the tub. This is called the "trunion rod". It has a screw clamp attached to it which allows the clamp to move back and forth along the rod, that clamp is attached to the actual shift lever itself. If you either put it in low range, by your hand lever in the cabin, you can adjust the clamp so that the lever is in low range and will smoothly go to the other positions, i.e. neutral and high, and 2wd. Trunion rod adjustment is commonly required after a lift.

If you don't fix it the shift fork will wear out. $$$$$

yeah that screw from memory is a 13mm size.. unscrew it (i put some wd40 on it since mine was rusty as hell and it woudnt move.. when you get inside the rig.. when you undo the screw and the thing if free to move you shouldnt feel the gears changing it should be just smooth move so no steps (only N).. it should be pretty smooth all the way across.. for mine it would go smooth from 2 to 4wd and then when it goes over N and to 4lo it would feel like normal shift.. then on the way back it would be smooth over n and 4 low and when it gets to 4hi and 2.. it would shift again.. so there is a limit on how much it can move.. I'd highly recomend extra hands to move the shifter from inside so you wouldnt have to get in and out from under the rig just to move the shifter a click or to see which position its in. And again make sure ur rigs tranny is set to neutral with the handbrake pulled and wheels chucked.
