In the pic attached what # is the 4th gear?

Not sure which one it should be.... Thanks

 

Not sure there is one. While I'm not familiar with the AX15 in particular, I do know 4th is a 1:1 ratio in that box and typically direct drive is derived by locking the input and output shafts together with a sleeve, the countershaft gearset is not in use.

 

gonna say 22 as 23 is its sync....better description herehttp://www.jeep4x4center.com/jeep-tr...aisin-ax15.htm

 

#22 is the main input shaft gear, it drives the countershaft (listed as "cluster gear" on the drawings) which provides 1'st second and third. If that #22 were to strip out, 1-2-3 should stop working but 4th gear should still work.

So.. is there a problem with 4th gear? Curious what the underlying issue is.

 

Yes/no lol. Took the jeep to the tranny shop to be rebuilt as the syncros were going out. He said the only other part that was needed besides syncros/bearings/seals/etc on a normal rebuild was the 4th gear or something to that nature. I'll get better clarification when I get down there to pick it up in a half hr. just wanted a general idea before I went down there so i had some idea what he was talking about. Still not to bad....total rebuild+labor to remove/install along with labor to instal my new master n slave came to $1188.33.

 

23 is 3rd and 4th synco 3rds on right 4th on left ...main drive gear

 

My currant ax-15 tossed 4th gear and reverse is going Ive got a couple of posts on here bout the problems. But my trans guy wont rebuild ax-15s he would rather get a rebuilt because after removeal and tear down the price is bout the sane

 

Then get a rebuilt one if you can. Cheapest I found online for a rebuilt ax15 was $900 +shipping and core deposit. Then add on labor to remove/install. Was cheaper to go the route I did end up going. Either way I love rebuilt tranny now. Feels so solid
