AX15 Manual Transmission:

The AX15 is a 5-speed, synchromesh, manual transmission. Fifth gear is an overdrive range with a ratio of 0.79:1. An adapter housing is used to attach the transmission to the transfer case on 4-wheel drive models. A standard extension housing is used on 2-wheel drive models. The shift mechanism is integral and mounted in the shift tower portion of the adapter housing.

TRANSMISSION IDENTIFICATION

Identification Code Number Location:

The AX15 identification code numbers are on the bottom surface of the intermediate plate.
The first number is year of manufacture. The second and third numbers indicate month of manufacture. The next series of numbers is the transmission serial number.

RECOMMENDED LUBRICANT
Recommended lubricant for AX15 transmissions is Mopar (R) 75W-90, API Grade GL-3 gear lubricant, or equivalent.
Correct lubricant level is from the bottom edge, to no more than 6 mm (1/4 inch) below the bottom edge of the fill plug hole.

Fill Plug Location:

Drain Plug Location:

The fill plug is located on the driver's side of the transmission case. The drain plug is located on the passenger side of the transmission case near the bottom.
Approximate dry fill lubricant capacity is:
- 3.10 liters (3.27 qts.) for 4-wheel drive applications.
- 3.15 liters (3.32 qts.) for 2-wheel drive applications.

TRANSMISSION ASSEMBLY INFORMATION
Lubricate the transmission components with Mopar (R) 75W-90, GL 3 gear lubricant during assembly. Use petroleum jelly to lubricate seal lips and/or hold parts in place during installation.
