Detailed Description

WS710781 is a manual transmission input shaft seal intended for specific Mitsubishi manual transmission applications, including Mitsubishi Eclipse, Lancer, Outlander, Mirage, Dodge Stratus, and Chrysler Sebring models equipped with the listed F5M42 or F5M41 transmission. The nitrile seal material is selected for sealing durability, while the measured dimensions help support a secure fit at the shaft and housing interface. If you are replacing a worn transmission seal on a Mitsubishi Eclipse, Mitsubishi Lancer, or Chrysler Sebring, WS710781 provides the dimensional match needed for the application.

Common Issues This Part Can Address

• Transmission fluid seepage at the input shaft area.
• Contamination entering the transmission through a worn seal.
• Loss of sealing integrity from age, heat, or wear.
• Moisture intrusion around the shaft opening.
• Service replacement for a damaged or hardened seal.

Installation Notes and Tips

Confirm the transmission code before ordering, since fitment is tied to the F5M42 and F5M41 units listed in the application data. Inspect the shaft surface and housing bore for wear, scoring, or debris before installation. Clean the sealing area thoroughly so the new seal seats evenly and can form a proper barrier.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and quality materials to support reliable sealing performance in manual transmission service. Part number WS710781 should be verified against the vehicle and transmission code before installation.
