The shift shaft seal is a common wear item on Harley transmissions due to the constant movement and stress placed on the shifter mechanism. This seal sits on the outer side of the transmission case where the shift shaft passes through, preventing fluid from leaking around the shaft. Installation requires removal of the inner primary, shift lever, snap ring, and washer to access the seal. Replace this seal whenever you notice transmission fluid seeping around the shift shaft or during routine transmission service.
