t-case stuck in neutral

Post by oros35 »

Need some help. I appear to be stuck between high and low. Second time it's happened. First time I just pulled in the driveway and it acted like it was in neutral. Bout 2 minutes fiddling with the levers and i was back in business. This time I pulled the lever for low and nothing, pushed it back again and nothing.

*** update I got it back in gear, not sure how, just moving levers and got it to work. Would still like to know how to fix it ***

I'm at our antique show and it's kinda blocking a bunch of stuff. Going to have to tow it out of the way. I'd really like to drive it around this weekend.

Any ideas to get it to pop back into gear? I'm not familiar with the internals of these t-cases.

And there's not a lot of wiggle room-the shift rod has to be just right in order for the T-Case to hit High, Neutral, and Low (at least mine is that picky).

I'm thinking you guys are right. Need to adjust the linkage.

RMS' advice about checking the transfer case mounts is worth doing, especially since you'll be under the truck anyway. Could be a combination of things - linkages, mounts, and internal wear - causing the problem.

When I removed the transfer from the frame on my truck, a couple of the transfer case insulator spacers were bent, indicating that the transfer case had been twisting around on the mounts.

Mine has no neutral. At least there are NO detents for a neutral.

mine doesn't have detents for high and low, either :P
if you stick the lever half way between, you'll find it. it's a narrow range for neutral

Certainly check to see whether case is loose on its mounts. I'll add this; the hi-lo shift fork may be loose and slipping on the shaft, have seen this a few times. Speaking of a neutral position, the stainless shift shafts we custom machine for these have an added center detent for a designated neutral position. Nice addition for safety, maintenance, etc.
