94xj trans not shifting
1. Year of your XJ/MJ.
1994 jeep cherokee xj sport
2. Engine (I.E.: 4.0, 2.5, 2.8).
4.0 inline 6
3. Transmission (Manual or auto).
auto and I make the assumption its an aw4
4. Differential/transfer case.
dana 30/35 with a np231
5. Any other model year specific info that would apply to your tech question.
Ok Here is the problem. The Jeep has 205k and the trans has shifted fine until today. I had a guy coming to buy it so I went outside to drive it to the store one last time and.........
I put it in drive which is how I drive it around town so it wont shift to od and lug with the stock gearing, and it wont pull. You could give it gas and feel that it was trying to move but wouldnt. I then pulled it down into what the shifter says as 2 and it takes off fine. You can then shift it up through all the gears fine. However when giving it gas to use a passing gear it will not gear itself down. When you come to a stop you have to downshift it and take off. Its almost like a manual valvebody in a c4 or something. Any ideas what the problem is? I adjusted the cable on the tb hoping that would help and nothing.

And after driving it more here is how it does on the shifter I have a 2, a D, and OD. When you put the shifter in OD the Jeep does not want to mover at all.
When you put it in D it trys a little harder
And when you pull it to 2 it is like normal and should be.
So you take off in 2 and shift to D and you can feel it shift to second and then drive real fast.
Then if you try to hammer it while going it will not gear itself down.

I would think TCU or Shifter Solenoids...
I was trying to narrow down my trans issue a while back, did all the adjustments, replaced the tps, and it ended up being my NSS even though I wasn't getting any of the classic symptoms. I would phone some wreckers or look for parts xj's and see about swapin' a TCU in there because as far as I know, auto parts stores don't sell these units, or know what they are even. You can buy ****ing solenoids new tho.
Hopefully you figure out your issue soon.
