I have a 1976 Wheel Horse with a footie Transaxle Transmission in it. This is a 3-speed with Hi Lo range in it. In the clutch part of the Transmission, a gear was found with 2 teeth broke off. Since this gear is no longer is available. It is only a matter of time with it will completely fail. So can any one help me in keeping My WHEEL HORSE going and going and going. Thank you for any help you can give, Frank
