This is the OEM transmission rear output seal for cars with the S6S420G or GS7S47BG transmissions. It is a good idea to replace all the seals on the transmission whenever replacing a clutch as it is much easier to do while the transmission is down off the car and these seals commonly develop leaks over time. This seal works with either the manual transmission or the SMG transmission.

Our standard gearbox rebuilding includes complete disassembly, thorough cleaning, and close inspection of all parts. We replace the synchro rings, bearings, seals and gaskets. Syncro detents are increased for better gear engagement.

These are the transmissions we used in our Grand-Am Championship winning E46 M3. They provide smoother and faster shifts with less likelyhood of missed shifts. Additionally, we have found the rebuilt transmissions last longer than the brand new factory transmissions.

The gears have a polished finish for smoother shifting and lower gearbox temperatures. Also the reduced friction will help produce a mild increase in rear wheel horsepower.

The benefit of having a magnetic drain plug is over time with use, all metallic particles floating in the gear lube from wear will be captured at the drain. This will greatly reduce any possible damage and clogging from normal transmission wear. With the drain plug holding on to those particles you're able to clean the plug at each service to ensure there isn't constant build up within the transmission or differential.
