I have removed my AX15 for rebuild. I'm a little nervous about rebuilding it . The fluid came out dark brown to start . 3rd and 4th are grinding a little . 3rd has been rough for about a year and a half. I have rebuilt a 5 speed Harley trans but never an AX15 . I have a factory service manual which has a nice trans section . I'm not to sure what to order at this point in the way of parts. Guess wait and see. Getting it apart is not the problem. Waiting for parts and forgetting how it goes back together is. If any one has any helpful suggestions I sure would appreciate the advise.
