Romain Posted September 28, 2021 Share Posted September 28, 2021 OK, I'm nearing the end of my mechanical assurance on my MJ. One of the last things on the list was to have the transfer case rebuilt. I took it out and it was rebuilt by "TheGearShop1945" in Baltimore. I've put it back in and hooked up all the linkages. So the problem is it won't shift at all out of 2H. It feels like the linkage is connected to a fixed spot rather than that elaborate dog-leg shifting system. I'm in the early stages of trying to figure out how the heck to begin trouble-shooting it. Any ideas? For those who have followed my MJ, I've removed the lightning bolts and put on the '86 orange stripes. It looks very nice.

jdog Posted September 28, 2021 Share Posted September 28, 2021 Try disconnecting the linkage at the t case and see if the linkage moves freely thru the gears, if so see if you can shift the t case manually. Link to comment Share on other sites More sharing options...
Romain Posted September 28, 2021 Author Share Posted September 28, 2021 Should I be able to move the linkage by hand? How much resistance should it have? Romain Link to comment Share on other sites More sharing options...
JMO413 Posted September 28, 2021 Share Posted September 28, 2021 With the linkage unhooked the shifter should move very free and easy. Link to comment Share on other sites More sharing options...
cruiser54 Posted September 29, 2021 Share Posted September 29, 2021 are you trying to shift it sitting still? Link to comment Share on other sites More sharing options...
Romain Posted September 29, 2021 Author Share Posted September 29, 2021 It's fixed. The shift cam lever was in the wrong position. It was set to push up and over the top where it should have been set to push down and under (4 Wheel Low would be straight down). I took off the shift cam lever and flipped it over (90º) so it shifts down and everything is swimming now...... Commendations to the TheGearShop1945 for the work as the case runs great (after the 90º flip). It was my inexperience with the shift lever to not understand that trying to go into 4WD, the link was pushing the wrong way.... I went to the salvage yard to see a similar one and it was immediately obvious I was pushing in a no-go direction. BTW, LKQPickYourPart in Mt Airy, MD has a NP231 AMC transfer case in a 1988 Jeep Cherokee if somebody is in the market for one. Thanks to JMO413 , jdog, and cruiser54 for the tips. Cruiser - I've done half your ~33 items, so far. Romain Link to comment Share on other sites More sharing options...

You may have noticed the dash is missing from the XJ. It is in my garage. The interior color matches my MJ. Link to comment Share on other sites More sharing options...
Romain Posted September 30, 2021 Author Share Posted September 30, 2021 I did notice that. The "dummy" cluster was sitting in the drivers seat too. LOL The underside it a little rusty, but there is some good mechanical salvage left for the '87-'88 RENIX pulling. I've thought about swapping out the bench for bucket seats (after recovering them), but the bench has grown on me, plus I like being able to have a third person in the cab.

87MJTIM Posted September 30, 2021 Share Posted September 30, 2021 If it was a full cluster, it wouldn't be there. Link to comment Share on other sites More sharing options...
