Detailed Product Overview

InMotion WS7929S is engineered to maintain a tight seal at the transmission manual shaft area, helping keep moisture, dirt, and road debris out of sensitive internal components. The nitrile construction provides the material profile commonly used in transmission sealing systems where consistent contact and fluid resistance matter. This seal is a practical choice for service work on Ford Ranger, Ford Explorer, Ford Crown Victoria, and related rear-wheel-drive and truck applications, as well as select Lincoln, Mercury, Mazda, and Jaguar vehicles listed in the fitment data. If you are replacing a leaking transmission shaft seal on a Ford F-150, Mustang, or E-250, WS7929S gives you a dimensionally specified replacement part that matches the listed housing and shaft measurements.

What It Helps Address

• Transmission fluid seepage at the manual shaft area
• Contamination entering the sealing interface
• Wear-related seal hardening or loss of elasticity
• Moisture intrusion around the transmission shaft opening
