Detailed Description

This InMotion manual transmission output shaft seal is engineered to create a secure seal at the transmission output shaft, helping reduce fluid leakage and limit the entry of dirt and moisture. The polyacrylate sealing material is selected for dimensional stability and consistent contact, which is important in older Ford Type E and Ford Type F transmission applications as well as select Mazda transmission-equipped Ford and Mercury vehicles. Use WS2443 when servicing a leaking output shaft seal on vehicles such as the Ford Mustang, Mercury Capri, Ford Pinto, and Mercury Bobcat with the listed transmission configurations. Part number WS2443 is also a useful reference when matching the seal dimensions to the housing bore and shaft diameter during transmission repair.

What It Helps Fix

• Transmission fluid seepage at the output shaft
• Contamination entering the rear of the transmission
• Wear-related sealing loss around the shaft surface
• Moisture intrusion that can affect internal transmission components
• Service issues on Ford Mustang, Mercury Capri, Ford Pinto, and Mercury Bobcat applications with the listed transmissions

Installation Notes and Tips

Confirm transmission type before installation, since fitment varies by Ford Type E, Ford Type F, Mazda M4M-D, Mazda M5M-D, Mazda R14M-D, and Mazda R15M-D applications. Inspect the shaft surface and housing bore for wear, scoring, or debris before installing the new seal. Clean the sealing area thoroughly and verify the dimensions against the original part to ensure proper seating.
