Rolling in gear

So today I finished my brakes and rolled the jeep into the driveway for a wash. After stopping, I put the jeep in gear so I could jump out and block the wheels. This is the first time I have stopped the jeep while sitting in it as its a build in progress. But once I put the jeep in gear it kept rolling the same as it was in neutral. Messed with different gears and shifted the transfer case all around. Same thing. Ended up at the end of the driveway looking like "that guy" trying to push a jeep that doesn't run uphill. Unsuccessfully might I add. I got the jeep back in the garage eventually, put the rear up on jackstands and tried more of the same. Shifting into different gears and moving transfer case with a person on each rear wheel pushing forward. Tires always spun.

Anyways, any thoughts on what the issue may be here or if there is one? I am going to contact the shop who rebuilt the transmission/transfer case a while back tomorrow but want to know what the experts here think. It's a 1970 with 232 even fire/t14/single stick d18. Transmission and transfer case have not been driven on since the rebuild.

 

id say its most likely an issue with the clutch but certainly can be any number of things if its all been rebuilt

 

Clutch was new, I started reading after you suggested clutch issues and have since tried to start the jeep in gear with clutch out, nothing happens at the wheels/tires. (It's up on jack stands). I have then tried moving transfer case every which way again and still no changes... Could something be going on in the transfer case? I can see the front output turn in 4wd and not turn in 2wd. So the linkage appears to be working.. Or could it be something in the transmission??

 

They may have missed the proper lin-up of the shifting forks in the tranny. Might pull the top off the T-14 and see what goes.

 

The linkage on the single stick t-case is not an ideal design. I would confirm that both shift rails are moving. You may have already done this but one rail is two position and the other rail has three positions. One of those three positions is neutral.

I think it would be best to get under there and have someone else move the stick. Or take the floor up so you can see it.

I really disliked my single stick in my 70 so I twin sticked it. Much better.

 

Did shop install transmission output gear

 

Clutch cable adjustment too tight?

 

This sounds like a real clue...
Try locking the front hubs, then put it in 1st gear of the transmission, with the transfer case in either 4 hi or 4 low, then check to see if the front wheels turn.

If the front wheels are turning with full torque (not just gear drag from cold gear lube) and the back wheels aren't, then your problem may not be in the transfer case or transmission at all.

Let us know what this check shows.

Ok, so I completely loosened the clutch cable and no changes. Still have the same problem. So I don't think its a clutch adjustment issue.

I have no idea what the transmission output gear is, but thy probably do, I will ask.

Just dropped it off at the shop that did the work, I dont know anything about transmissions or transfer cases, I'll learn one day. Found out they didn't even do the work in house, that they have a "guy." Kinda disappointed, I guess it's part of it but I had to take it back the day after I got it back as it is, and the transfer case linkage was on backwards, I switched but its the principle. Paid them a lot of money too.

 

i just dropped it off :/... but I don't have the front driveshaft on either so I wouldn't be able to perform this. I was just looking at the output on the transfer case. What would the issue be if this was the case?

 

Something broken in the rear axle is what I was thinking when you stated the front output shaft is turning when 4WD is selected in the transfer case. With no front driveshaft in place you can't really tell whether true torque is coming from the output shaft or if it is just turning from gear drag from cold lube oil.

You dropped it off at the shop that did the transmission rebuild? Then let them sort it out.

Hopefeully they are able to. Thanks everyone for the replies!
