The AX15 transmission has always been a great transmission able to handle the torque and horsepower of most V8s. The biggest problem has always been the availability of new units. With the lack of availability of a new NV3550, we revisited the possibly of obtaining the Aisin Warner AX15 transmission and were successful. Although the torque specifications are not listed on this transmission in any service manual, we feel it‘s similar enough to the NV3550. The NV3550 was the transmission that superseded the AX15; and Jeep used the same engine with the same vehicle ratings.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 for an AX15 direct replacement, AX5 replacement, Peugeot replacement and the 1980 to 86 Jeep 4 & 5 speed replacements.
