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 is 21 spline.
The AX-5 was used in all 2.5L equipped Wranglers (YJs and TJs)
equipped with a 5-speed manual transmission. Its usage is similar in
Cherokees (XJ) and Comanches (MJ).

installed. Friendly neighbor included.
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
compared to the AX-5. 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.
