|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|

|Jerry Bransford||The Redline MT-90 is a 75W-90 GL-4 gear lube which meets the 75W-90 GL-3 spec for your AX-15 transmission. GL-4 is backwards compatible with GL-3. And even though the Synchromesh you bought may be ok in your AX-15, it technically doesn't meet the spec so I wouldn't run it if it were me.|

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!
