Jeep LS Swap Kits

  • The AX15 transmission has always been a great transmission able to handle the torque and horsepower of most V8s. The biggest problem now is the availability of new units. With the lack of availability of new NV3550s, we revisited the possibly of obtaining the Asian Warner AX15 transmission and were successful.

The NV3550 was the transmission that superseded the AX15; and Jeep used the same engine with the same vehicle ratings. With the availability of AX15 transmissions, we can now offer some additional transmission retrofit applications.

AX15 Direct Replacement:

The AX15 was use between 1988 to 1999 in the Jeep vehicles. Since these Jeeps are getting up in mileage, a new AX15 makes sense as a direct retrofit. Available in both an internal and external release bearing design.

AX15 retrofitting the AX5:

This is a newer kit for all 4 cylinder Jeeps 1987 to 2002. The AX5 is considered a light duty transmission compared to the AX15. Jeeps equipped with larger tires and lower gears in the axle & transfer case may find the weak link in the drivetrain is the stock transmission. You can now install the AX15 in place of the AX5 to gain some drivetrain strength.
