AX15 5 Speed Transmission Retro-Fit For The AX5 4 Cyl. 5 Speed Ext. Slave

This kit is designed to fit the 1995 and newer AX15 transmission. Earlier model transmissions can use a stock pilot bushing, one with a .590" I.D. We recommend that the stock flywheel be removed and resurfaced at a machine shop. A new clutch disc and release bearing has been provided in this kit. A new pressure plate is also recommended before installing your new transmission. We offer a Centerforce pressure plate, Part No. CF361914. Before disposing of the old AX5 transmission, you will need to retain the shifter housing from that transmission. You will also be using the stock 4 cylinder bellhousing and stock release arm and crossmember mount.

The transfer case must have a new input gear installed to fit to the AX15 transmission. If retaining the NP231 transfer case and because the new transmission is longer, we highly recommend a fixed yoke kit to be installed during this transmission swap. This will allow for a new, longer rear drive shaft. The Atlas 2 speed or 4 speed transfer cases are also an excellent upgrade to your Jeep, and this would be the perfect time for this additional upgrade.

ASSEMBLY PROCEDURES:
1. Refer to a service manual for the removal of the stock AX5 transmission. Also remove the pressure plate, disc, and flywheel.
2. Resurface the flywheel and remove the old pilot bushing. Check the new pilot bushing on the AX15 pilot tip and install into flywheel if it is the correct size. Mount the flywheel to the block and torque the flywheel bolts to factory specifications.
3. Install the new clutch disc and pressure plate onto the flywheel.
4. Install the two new dowel pins into the adapter plate. The pins are a press fit.
