The 25 spline output shaft seal has been discontinued by Mitsubishi, but we have located a very high quality aftermarket piece. This seal is practically impossible to replace without removing the transmission, so its a good idea to replace anytime the transmission is removed for service.
These are a very common item to leak on 3000GT and Stealth Getrag transmissions as they are one of the few seals continuously immersed in transmission fluid.
Its also a great time to upgrade your fluid to redline MTL using our driveline fluid package.
