How-to: Rebuilding an AX15 Transmission
Due to popularity and reasonable parts sources, the Jeep Aisin AX5 and Jeep AX15 transmissions remain serviceable. Jeep dealerships, 4WD transmission shops and Jeep owners can rebuild these transmissions, and both Mopar and aftermarket service parts are still available. Having rebuilt light-, medium- and heavy-duty truck manual and automatic transmissions for more than 50 years, I view the AX-series units as “busy” designs from a service standpoint. I outline the entire rebuild process in a free HD video available below and the YouTube Channel…If, after carefully considering the ‘how-to’ steps and photos, you decide not to rebuild your original transmission, consider a new Aisin replacement unit from Advance Adapters.
The steps in the video will serve owners of the Jeep XJ Cherokee, Jeep YJ Wrangler and Jeep TJ Wrangler. There are also Dodge Dakota, GM/Isuzu and some Toyota transmissions that feature the AX15 design. You will want to check out the synchromesh parts design issue for the 3rd/4th synchronizer assembly on late AX15 Jeep transmissions. There is an excellent discussion at the 4WD Mechanix ‘Tech and Travel’ Forums regarding “earlier” versus “late” 3rd/4th gear synchro parts and other AX15 issues, click here!—Moses Ludel
