Newstar Manual Transmission Input Shaft Seal
The Newstar Manual Transmission Input Shaft Seal controls fluid retention at the point where the input shaft enters the transmission housing. As the shaft turns during gear engagement, the seal maintains continuous contact along the rotating surface, allowing motion while limiting seepage. This interaction occurs whenever torque is transferred from the clutch to the transmission, regardless of driving speed or load. Heat buildup and shaft movement are accommodated by the seal’s flexible design, enabling it to operate under normal driving conditions. During drivetrain servicing, technicians address this seal when working near the bell housing area, typically alongside clutch or input shaft work. The Newstar S-11556 is specified for M80, M90, M100, and M110 manual transmission models.
