I got a 89 cherokee with the ax-15 5 speed transmission. i wanted to change the oil but i came across a problem. i cant get the fill or drain plug out. Is there s special tool for this? a 3/8s drive is to big and a 1/4 drive is 2 small and its not a Allen wrench. Autozone was no help. i have 222,000 miles on the transmission and i dont think the PO ever changed the oil. after my second gear syncros ceased to exist any more i figured now would be a good time to change the oil before something els happens.

-thanks

 

i just had my brother weld a 3/4" nut to the piece and i took it off that way. but i think it is a 7/16 square drive which you can get at sears. just measure it and then go get the right tool from sears

 

'89 and a female square drive plug... i think you got a pugot not an ax15

 

uh why a sad face? u say it as if it was a bad thing.... and how would i know for sure what transmission iv got? i looked up cherokee specs and the ax-15 was used for the 4.0 I6. i figured that's what i have..?

 

89 is the conversion year for the manual trannies. The early 89's got the Peugeot, the later ones received the AX-15.

Here is a picture of the BA-10

You can see the seam at the top of the BA-10. This seam runs along the entire top and bottom of the tranny.

But the BA-10 has a bad reputation of being a weak, failure prone tranny.

 

saying it is faiure prone is being nice...i am on my third one! i got my first one rebult by my uncle for parts cost only and then i split the case in half. i got my next tranny for $100 and it hasnt failed me yet, if it fails again i am going to a GM LT1 V8 and a 4 speed auto 700R4
