The AX-5 is a light duty five speed transmission. It
looks similar to the AX-15, but smaller. It is manufactured by
Aisin in Japan. The input shaft is 1" 14 spline and the output
shaft can be 21 spline or 23 spline.
Usage
The AX-5 and the Peugeot BA 10/5 were used in all Wranglers from
1987-1989. After mid 1989, the AX-5 has only been used in 4
cylinder Wranglers (YJs and TJs). Its usage is similar in Cherokees
(XJ) and Comanches (MJ).

A driver's side shot of a BA 10/5 for
comparison. Notice how the
BA 10/5 doesn't have the regular ribbing on the driver's side.
The passenger side of the BA 10/5 does have regular ribbing. The
main case of the BA 10/5 is made of two pieces bolted together,
where as the AX-5 main case is one solid piece of cast
aluminum. |
