INSTALLATION NOTES:
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.
OPTIONAL ITEMS:
The AX5 transmission was coupled to a
21 spline transfer case. The AX15 transmission has a 23 output shaft. When
upgrading your transmission, you will
also be required to change out the input
gear of the transfer case.
716054 1987-1994 NP231 T/Cs
716095 1995-2006 NP231 T/Cs
716096 NP207 T/Cs
The transfer case shifter braket must also
be changed.

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.
SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the
components will void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion,
we strongly recommend that you contact our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter
components. We recommend that a service manual pertaining to your vehicle be obtained for specific torque values, wiring diagrams and other related equipment.
These manuals are normally available at automotive dealerships and parts stores.

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.
5. With the AX15 transmission on a work bench, remove the
front bearing retainer. Clean the surface of any silicone.
6. Apply a new thin film of silicon to the transmission face
where the front retainer was just removed. Install the new
adapter plate to the transmission. This adapter aligns to the
front input bearing of the AX15 transmission. We have
provided two clearance pockets on the adapter plate for the
old AX15 dowel pins. Install the six 10mm bolts and the
two 8mm bolts to retain the adapter plate.
7. Install the new seal into the new retainer snout. Then install
the retainer onto the adapter plate with silicone around the
outside edge to seal the retaier to the plate.
8. The stock 4 cylinder bellhousing should now be installed onto the adapter plate.
Make sure the new dowel pins in the plate align to the bellhousing. Install the new
release bearing onto the stock release arm. Install these components into the
bellhousing. Check for slave cylinder clearance on the adapter plate and bellhousing.
9. Most rebuilt AX15 transmissions do not come with a shift handle. If yours did then
skip this step. The AX5 shifter bolts to the transmission with four bolts and this is
a different bolt pattern than that of the AX15 transmission. Since a new shift handle
is hard to come by, we have opted to make the AX5 shifter work with the AX15
transmission. The shift body bolt holes are approximately a 1/2" of a hole off from
bolting on to the AX15 transmission. So remove the stick from the aluminum shift
housing and elongate the four holes to line up with the AX15 transmission hole, using
712563-S as a template. Once the holes line up with the AX15, you will also be
required to modify the oil splash sheet metal piece. The new modified shifter can
then be installed onto the AX15 transmission. Silicone should be applied on each
