Dana 300 lockup problem

I have an 83 cj-7. Just had transmission and transfer case rebuilt. Re installed and drove about 35 feet and rear end locked up. Had it in two high. It will drive in four low only. None of the high gears will work. any ideas...please help ready to roll her in the street and set her on fire...thanks....Phil

Have you looked at the t-case linkage and made sure it's operating the shift rods correctly? Maybe you need to talk to whoever rebuilt the t-case.

It's just a Jeep, and if you don't wheel it once in a while, it's not even that.

I think the linkage is working. It will move through the gears. And dude who built it has moved back to Australia....so I'm stuck..

The case is pretty simple and very hard to mess up a rebuild. I would look hard at your shiffter and linkage and see if there is a problem there.

If eveything looks good there drain the oil and remove the bottom inspection plate and check to see that the two set screws are on the shift forks and tight in thier respective holes. Chances are that one of them is loose and needs to be tightened. Not a big deal.
