poor shifting

I had rough shifting on my AX-15 trans. Switched from API GL-5 oil to GM Synchromesh. Significant improvement, especially when cold. Also available as Pennzoil Synchromesh: same as the GM stuff but cheaper:

The AX-15 has sintered brass synchros that don't tolerate sulfur in regular GL-5 90 weight oil. Better to use API GL-3 rated lubes like Synchromesh or Red Line MTL.

Yep, let it warm up. :)

couldn't resist.

Low gear oil would be my first guess and water inside the second.

The TJ tranny has no high water vent so they easily can get filled with water if you go too deep.

My '99 was the same... I switched to Redline synthetic and it's been much better.

well it seems that water was the main cause of mine going bad...now looking for the best ideas on relocating the vent lines?/ Bill ya got a link for that?? Jeff

There is the trouble, you don't 'have' a vent line. Jeep decided to protect every other part of the vehicle except the transmission.

I pulled the stooopid button vent out of mine and tapped in a piece of steel gas line to make a nipple for the vent line. I used transmission hose and ran it up by the battery then inverted the top in a cane handle loop. to make an air lock. Pointed the end down.

As I still haven't done mine, but will, what is the cane loop/air lock for?

You can demonstrate this in the house: Fill the sink with water Hold a cup with the opening facing down Push the cup into the sink Now, how much water is in the cup?

If you simply point the hose up, you have merely increased the necessary water level before you end up in the exact same situation. However, by pointing the opening down you create a situation where the air in the hose will prevent water from entering even if the water is well over the top of the hose.

Yup, just what he said. The stock ones come with a fitting that has a nipple end up with a cap over it. The cap acts just like the below mentioned cup.
