FJ60 transfer case stuck in neutral???

[NJFJ60]

Hey all,

I recently purchased an 87' FJ60 to do a v8 swap. The motor is in and running but, the truck won't move??? Clutch is working properly, and when I pull the transfer case shifter into 4H the light comes on the dash. It feels like it is going into 2H but, the truck doesn't move? It sat for 18 months before I bought so, maybe something is seized?

you should crawl under the truck and see what is going on with the shift linkage. There are two shift forks in the transfer case. One for 4wd vs 2wd and the other for Hi-N-Lo. The Hi-N-Lo shift fork is actuated by a set of levers (outer and inner) that rotates through about 90degrees. The levers are located on the top side of the transfer case at the right side (passenger side in US). If the clamp bolt on the outer lever is loose, the inner lever can slip down and disengage from the shift fork.

first check to make sure the linkage is moving the outer lever throughout its range of motion. if the truck is still not shifting you might try pulling up on the inner lever to see if it has disengaged from the shift fork. if it has, you might be able to reattach it, but be careful the inner lever doesn't fall inside the case. Some have had luck making this repair from the outside, but others have had to disassemble the transfer case.

Ok, thank you. I will check all that out tonight and let you know how I make out. Some suggested pulling the drive shaft and turning the transfer case yoke, while working the shift lever?

first check out the linkage. maybe it isn't connected properly. you can also raise one rear tire off the ground and should be able to turn the drive shaft. That's probably easier than taking the drive shaft off.

My lever had slipped down when I got my 60 years ago. I have no idea why it happens. All is well until you shift it, then it won't shift back.

I did the repair under the truck. It is a very nerve racking repair. I held the shaft with needle nose pliers, vice grips would have been better. Removed pinch bolt and arm, added a washer by slipping it on the shaft, grabbing it with pliers on the top, then slipping the washer down, then grabbing it again and putting the arm back on. If the shaft slides down, it goes in the case, then you have seperate the two halves to get into the split case.

You can grab the shaft or use a pry bar to pull it up then work the shifter if all is hooked up right, that will tell you what is wrong right away. If the arm in the case is sliding past the little notch it is supposed to ride in you will feel it fall into place, well fall up into place.

Ok, here is the latest. I have 4whl low but, nothing else??

 

[2mbb]

please give more information. Did you loose N, too? If you have N and Low but not Hi, then I would first suspect that your linkage is not moving the shift lever enough to engage low. Disconnect the linkage from the lever and try moving the lever by hand into low.

Inside the t-case the hi low " shaft " ( what you see going in to the t-case ) it's like an L in there it's moving a rod that move the fork it's needs to be a certain height, there is a washer on the exterior part preventing that .. the hole idea it's it can move but will not " actuate " over the rod that's connected with the low hi fork ..

Here is an old crappy pic of what I'm trying to explain what you see here it's the hi low L " shaft " and the rod which connects with the hi low fork ..

Are you running twin sticks or asingle stick? With a twin stick the linkages can be hard to actuate especially the high low, that's because of the orientation of the lever on the tc. Check out Georg's twin sticks and how he modified the lever on the case so it would give enough leverage. Or you could go redneck like me and weld a bolt to the side.

Ok good news!! Got 2H but no 4H. Seems like the linkage is bound up. Sprayed it down with wurth rust off. So, tomorrow I can do a more proper test drive!!

You sure it is not binding for some reason? Mine will bind when shifting from 4H to 2H if my wheels are turned with from a start (like I pulled into a parking spot at an angle or something). I am sure my tranny and t-case need some work but I can usually get mine to disengage by backing straight for a short distance then attempting to shift.

i reccomend trying this, i cannot disengage from 4H without putting the car in reverse and shifting back to 2H. i only need to move back 2 inches or so and it lets me shift. 4L doesnt do that, just 4H for my truck. yours might be doing something similar

Try this.

Where are you located in Jersey?
Also have you drained the oil to see if there are any chips/metal pieces?

 

[NJFJ60]

I haven't looked at the fluid. I am in martinsville. Exit 33 off 78

 

[StevoJonesFJ60]

I would check the fluid, usually the transfercase is pretty stout but things break.

you need to post some pics of what you have so you can get better input. the more info you provide, the better we'll be able to help.

sounds to me that you have linkage issues. i'd bet there's nothing wrong with the t-case ( internally ).
