for you ax15 owners out there that seem to be having a bit of trouble shifting your transmission through the gears.... try the "REDLINE" mt90.
when i did all of my drivetrain work, i put this stuff in my transmission. before using this mt90, i used the synchromesh. synchromesh works pretty good, but there was still a bump going into 3rd gear from the sinchronizer. this mt90 has eliminated this bump
give it a try! i think you'll like it.
you tj drivers can use it in your transmissions too... check for your application.
