4-Speed Transmission

After 30 years without one i'm loving being in the Jeep world again. My last one was a 79 CJ5. Can't post pics yet but will soon. I got my Jeep in June of this year. It is a 95 YJ with a 4 cyl. I appear to be the 5th owner on the car fax. The guy I bought it from said the previous owner had problems with the 5 speed transmission and when he swapped it out he put in a 4 speed. Nothing under the Jeep looks modified and it runs fine. Great gas mileage and the rpms are reasonable on the highway. I haven't taken it out on the interstate yet. Any thoughts on this? What transmission would have worked? Should I look at an upgrade? This will not be a rock crawler or mud crawler. Just a Jeep to ride trails and clear cut roads and some mud. Thanks!

4 speed manual or automatic? Going to be tough to ID the transmission without pictures or at least casting numbers. If you can upload pics to a host site and post the URL, one of us will link them for you.

Perhaps it's the rarely heard of AX-4.

If it suits your needs I wouldn't worry about it, if you get itching for a change to a 5 speed, I'd skip the AX-5 and swap in a AX-15 instead.

After looking over trans and doing some reading the ax4 is externally the same as an ax5. Didn't see any numbers. You can put it into 5th going down the road but its like putting it into neutral. So for now, it's 4 speed Jeep with me looking for 5th out of habit 😊

There are a number of replacements for the AX5 behind the 4 cylinder, I believe

There are threads telling how to fix 5th gear. There is also a fix for the problem. Problem is a snap ring popping out. The fix is put snap ring back on and install a collar over it.
