DRIVESHAFT

It is extremely important to maintain the original driveline angle. Excessive driveline angles will cause vibrations and may damage the transmission. All TKO transmissions use a standard 31-spline yoke which is available for $79. When installing the slip-yoke, be careful not to damage the rear seal, as this will result in oil leakage. There is a rubber donut on the output shaft that is used to prevent any remaining oil in the transmission from leaking during shipment. While you may remove this donut, it is not necessary. It will simply slide forward on the shaft when the slip-yoke is installed. If you do remove this donut, sue extreme caution to avoid damaging the rear seal. The slip-yoke must be able to stroke freely on the transmission output shaft without bottoming out while maintaining maximum spline contact. Therefore, proper driveshaft length is critical.
