How-to: Rebuilding a Jeep or Dodge
Dakota AX15 Transmission
If you need to rebuild your AX15 transmission
or are a repair or 4x4 shop seeking instructional guidance for
your techs, see the Vimeo On
Demand streaming how-to: Rebuilding the Aisin AX15
Transmission. The freshly built
AX15 transmission is now a 4WD Mechanix Video
On Demand prototype for a "textbook"
rebuild. Save considerable time and expense, take advantage of this 30-day
Note: One of the most popular articles at the magazine for the last four years has been the AX15 rebuild.
This level of viewer interest has prompted the production of a detailed, 94-minute HD video that is now available
at Vimeo On Demand. The streaming video provides all of the
content formerly available in the article plus additional commentary and
new details. If you want a successful rebuild and insight from
a bestselling automotive author, then you will want access to this HD video! See the "trailer"
I enjoy rebuilding the AX15 transmissions. A more
sophisticated unit than most domestic (U.S. design) Jeep gearboxes, the Aisin AX15 borrows architecture from
European and Asian transmission designs. Fitting parts precisely, taking careful measurements of the
tolerances, and deciding whether to reuse or replace various parts are just some of the reasons why the AX15 is
a much busier, yet gratifying, transmission to rebuild. Some find this daunting. The 94-minute
streaming HD video how-to at Vimeo On Demand can overcome these concerns—or provide the level of information
you need for an informed decision.
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 45 years, I view the AX-series units as “busy” designs from a service standpoint. If,
after carefully considering the 'how-to' steps and photos, you decide not to rebuild your original
transmission, consider a replacement unit from Mopar™ or Advance Adapters. The
streaming HD video at Vimeo On Demand 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
can gain a valuable understanding of the AX15's functions by watching this
"third-party" YouTube video embedded at the forum posts on AX15 rebuilding issues. The presenter does an excellent job of
describing the functions of this transmission. You will find this video helpful. View it and my how-to HD video
streaming rental for a thorough knowledge of the Aisin AX15 transmission! You will also 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,
