Sounds like the starting maybe be a fuel pressure issue. there is a one way valve somewhere that stops the fuel lines from draining back towards the tank while the vehicle isn't running. could also be a weak pump. the poor running could really be anything. vaccum leaks, electrical or spark problems, or fueling. I would start by checking for vac leaks, checking fuel pressure and cleaning grounds and contacts in the engine bay. At least that will rule out the easy things and maybe give you some leads as to what to check next. May also be worth checking the spark plugs. I recently had a poor running issue that I could not track down. Finally went to change the plugs after a few weeks and found the cylinder 1 plug arm to be almost touching the electrode. further inspection revealed nothing wrong in the cylinder (maybe some detonation or foreign object) other than that and new plugs solved the problem. Good luck.

No need for the ax15 TC linkage. I got all of it and used none of it. The ba10 linkage works great once you flip around the bracket that bolts to the transmission. Just need to drill out the mounting hole in the bracket for the slightly larger bolt hole in the ax15.

I just completed the same swap on my MJ and simply ordered the clutch kit for a 96 XJ. Engages at a reasonable height.

I just completed the swap from ba10 to ax15. I used the orginal ba10 crossmember with ax15 mount and no new hole drilled at all. Also, the ba10 linkage will work. You need to remove the metal plate that holds a pivot bushing from the ax15 and the bracket that was bolted to the ba10 needs to be flipped around and bolted to an open hole on the ax15. The bolt hole is larger than the one on the ba10 so the mounting hole on the bracket needs to be enlarged. Other than that, everything about the swap was a complete bolt on.

Just bought an MJ to use as a daily during the snowy season. I had to run through the brakes and clutch hydraulics but with just over 200k that just seems like the prudent thing to do anyhow. Before that I had an audi with a big turbo pushing 24+ psi many times daily. That car and motor both had 240k on it when I sold it and ran like a champ.
