ax15 re-ish-build

[wheelsaz08]

the trans in the jeep currently grinds trying to shift into 3rd and will usually never actually engage. ive tried double clutch, rev matching, slamming the living piss out of the shifter, all to no avail. its extremely random i can get it into 3rd gear. all other gears will engage, but feel some what "mushy" when beginning to shift then engages rather harsh. also, going from any forward gear to reverse will usually grind at first till the jeep rolls a bit, then shifts fine.

 

clutch master and slave are both in good working order. trans oil was changed less than 6 months ago, still full.

 

it obviously needs to be pulled and torn apart. I'm guessing a syncro is bad... i have another ax15 (2wd) that shifted fine when i pulled it. both are pre 94's. i am cheap/broke and will be for some time...

 

questions:

 

since I'm obviously going to pull them both apart, how involved would swapping just the output shafts/tail sections be? as in how far apart do i need to go if that makes sense. or should i just take them both completely apart and use the best of each?

 

thanks in advance

There are a a few videos and manuals on the ax-15 online.

Far as I understand it the swapping the the outputs is very involved, but you're disassembling it anyway so.... doesn't seem like going that much farther .

 

I'm not a expert on the ax5 and ax15, but I've been reading on rebuilding them cause I've got a 90 ax15 I'm going to convert my 85 XJ to. Tempted to pull it apart to rebuild it first but it out of a running XJ that was supposedly shifted smoothly.

 

Anyway if you look at how the gears are arranged in the case I've been wondering if 1st through 4th gears could be removed and swapped leaving 5th and reverse and output tail shaft alone.

If it can be diassambed that way I'd think you could pull and replace gears 1-4 from the 2wd to the 4wd without much hassle.

 

Hopefully somebody who knows these transmissions better will say for sure.

I'd check for bent shift forks first. 

Rail shifter transmissions like this can act up if the shift rails get bent and do all kinds of bad things just like this.

 

I never had an AX-15 apart, so take this info with a grain of salt.

Haven't torn either of them apart yet but plan to at least get into the 2wd this weekend. Thanks for the replies and I'll be sure to update asap
