Transmission

[Dave Vig]

Wondering if someone can help me. I have an 88 4wd, 4.0, 5 speed short bed Comanche. Pretty sure it has the Renault tranny in it. Attached is a picture of an AX-15 from a 84 Cherokee. Will this fit my Comanche? Any help would be great 

thank you

No I don't think that will work. Ax5 came with the 2.5L. What's wrong with your ba10?

The captions says it's an AX5 from an 84.  The AX5 was behind a 2.5 engine, not the 4.0.

 

The AX5 will not bolt to a 4.0.

 

Also, the AX15 didn't come on the 4.0 until mid-89 model year.

 

Keep looking.  That is not what you want.

Thank you for the replies. My ba10 seems like the synchros are going bad. Put in a new clutch had the toughest time getting it to work properly. Finally a mechanic down the street got it going. It’s running great but putting in reverse is slightly grinding unfortunately

are we certain that's a problem with the trans rather than the clutch not fully disengaging? 

[Dave Vig]

Pretty sure. Put in a second clutch master after the new clutch install. Everything is going into gear fine except reverse. It’s been a pain in the rear 

[scaleless]

Reverse is the only unsynchronized gear, so if the clutch was dragging, reverse would be the first to show issues.

 

That said, I think an AX15 swap is still a worthwhile investment even if your BA10 isn't trash.

I just put in an ax15 and when I was done I didn't have reverse either. Had to bleed the master 3 or 4 times  now it works great

[Pete M]

I would try bleeding it a couple more times, just in case.   

[cruiser54]

Or, DON'T bleed it.

 

Try this. Pump the clutch pedal about 40 times. Walk away for 10 to 15 minutes or longer. 

See how it works. There's also a procedure to get the FUZZ off the the new clutch disc.
