1979 Jeep Wagoneer

1979 Jeep Wagoneer

I am working on a Jeep Wagoneer. It was delivered to the shop Saturday. It arrived minus the front drive shaft which looks like it broke and damaged the transmission pan on the way out.

The Jeep has the Borg Warner Quadratrac transmission so it won’t move unless both axles have traction. There is an emergency override that is supposed to lock the center differential but switching the switch in the glove box has had no effect on the transfer case. I suspect vacuum lines are loose or broken.

I got the missing parts and reassembled the drive shaft last night. I was hoping to be able to drive it into the shop. Well after a lot of effort to get the drive shaft in place with the truck on the ground in front of my shop, I found that the truck still won’t move. It looks like the damage to the transmission pan has caused it to loose all the fluid.

I guess I will have to drag it in to the shop and remove the pan to repair the leak. The engine runs rough when it revs. Maybe bad gas or maybe a clogged filter.

UPDATE: I put the Jeep on the lift last night to look at the transmission leak. There was no fluid it he transmission so even with the front drive shaft installed and the engine running, the Jeep would not move. I used my XJ to tow it in front of the barn door and then let it roll into the stall.

It took me a while to find all the cross member bolts and get ti out of the way to see the damage. It looked like on corner of the pan was simply bent down. However when I dropped the pan, I noticed that part of the sealing flange of the transmission is missing. The drive shaft did quite a bit of damage on its way out. I was able to straighten the pan, but I am still considering options on how to make it seal.

UPDATE: The Wagoneer was running well and the transmission repair was holding so I took it back home. The owners seemed happy to be able to drive it for the first time since they bought it.
