AC0QR I have an AX-15, and put Super Tech (Wal Mart) 10w30 engine oil in it. That was 25k miles ago, and I have not had any problems. It ran/shifted fine before the change at 105k miles, and it's fine at 130k miles (now). Just my $0.02

So is the 10w 30 synthetic just as good for the tranny as the MT-90? What is tranny change intervals? I do not do any deep water crossings.

I found an old service manual and it looks like my previous owner was using GL-5 75W-90. Is it safe to just change the fluid to the redline MT-90 or should I get the tranny flushed by a shop first?

4.0l sahara Ya you need a gl-3/4 gear oil and redline mt-90 is perfect for it. I ordered mine from summit.

You have a different transmission.The 2006 has a NSG370 Syncromesh is fine for yours

The OP has a AX-15. They do require different types of fluids.


To the OP...

The AX-15 has to say the least crappy sincro's. Syncromesh is not what you want to put in it.

You would be correct to run the MT-90 or MT-mtl.

The AX-15 are happy with the fluid and shift better. IT WILL NOT hurt the sincro's in the trans. The syncromesh mite. The ax-15 doesn't much like the syncromesh.

Manual Transmission Fluid Change--Need Opinions!!

I have done extensive searching for an answer with very little luck. I am looking to change the fluid in my AX15 transmission and cannot find a suitable fluid. Members on most forums praise Red Line MT-90 which I like as well, however it is a GL4 fluid..which should be corrosive to the syncros.
Gear Oil and Transmission Lube - Red Line Oil MT-90 Manual Transmission Lube
The specs for the AX15 call for a 75w90 GL3 fluid, but finding a GL3 fluid has been like finding bin laden I picked up 3 qts of Pennzoil Syncromesh which covers some Chrysler req. However, it does not state the viscosity or GL rating. Is it ok to use Syncromesh? Thanks!
