AX5 transision to AX15
 

I have a 1990 Wrangler with an AX-5 in it. It also has a 1988 Chevy 4.3
liter V6 and very low rearends in it. I'm wearing the trany out at 65
mph, I'm turning 4100 rpms. I know I need to change the ends, but right
now I want to change the trany.

Dimesionaly, is the AX-5 inter-changable with an
AX-15??????????????????

Any help appreciated.

Re: AX5 transision to AX15
 

An AX15 isn't going to do much for your rpms. It has almost the same gear
ratios as the AX5. Both are overdrive transmissions. If you are turning
4100 rpms at 65 mph in fifth gear, then you have some low axle ratios
indeed. Many people would envy the crawl ratio you must have. Can you get
better road speed with bigger tires?

The AX15 and the AX5 use a different bell housing. They use the same
transfer case bolt pattern, but the transmission output shaft spline count
will be different. This means of course that the transfer case input shaft,
that it mates with, is also different. Afaik, you will need a custom
adapter bell housing, such as you might find at Advance Adapters.
http://advanceadapters.com This is the same bell housing that one would use
to adapt a small block Chevy V8 to an AX15.

The reason to do this switch is transmission strength, not gear ratios. The
AX5 is marginal for six cylinder applications. Although much depends on
your driving style, you may break fifth or reverse gear if you continue to
use the AX5.

Hi Randy,
Your Japanese AX5 four cylinder transmission already has a slightly
higher overdrive:
http://www.tommyjeep.com/apps/ratio/...#Transmissions
Switch the cylinder switch on your Tachometer, as 65 MPH with 35"
tires in fourth/direct would mean you have 6.57 gears:
http://corvetteactioncenter.com/tech/tools/index.html
No the AX 5 and 15 will not interchange.
