Detailed Description

The InMotion WS9613S manual transmission output shaft seal is engineered for a precise fit at the output shaft opening, helping keep contaminants out and lubricant in. Its nitrile construction is suited for sealing duties where consistent contact, dimensional accuracy, and resistance to leakage matter. With a 1.5-inch shaft diameter and a 2.3769999999999998-inch housing bore, this seal is sized for the applications listed in the fitment data, including rear-position and transmission-specific installs across multiple GM and Jeep platforms.

This part number, WS9613S, is a practical replacement choice for maintenance on older manual transmission and transfer case setups where seal wear can lead to seepage or contamination. It is also a relevant service part for Chevrolet S10, GMC Sonoma, and Jeep models that use the specified transmission or spline configuration.

What It Helps Fix

• Transmission fluid seepage at the output shaft
• Contamination entering the transmission or transfer case area
• Wet housing or driveline residue around the seal surface
• Wear-related sealing loss from age or mileage
• Service issues during manual transmission or transfer case repair
