InMotion WS6712NA Automatic Transmission Oil Pump Seal - Front

Automatic Transmission Seal for GM and Import Applications

InMotion WS6712NA is an automatic transmission oil pump seal built with polyacrylate sealing material for a secure barrier against fluid loss and contamination. It is used in a wide range of front-position applications, including many Chevrolet, GMC, Buick, Pontiac, Jaguar, Jeep, Suzuki, Honda, Acura, and Rolls-Royce models.

For transmission service work, this seal is specified by dimensions and fitment coverage, making it a practical choice when replacing a worn or leaking seal on supported vehicles.

Detailed Description

The InMotion WS6712NA transmission seal is engineered to maintain a tight seal at the oil pump area, helping keep transmission fluid where it belongs while limiting the entry of debris and moisture. Its polyacrylate construction is selected for sealing durability and dimensional consistency, which matters in older GM THM350, THM400, THM350C, THM250C/M31, THM375B, THM180C, and related applications. If you are servicing a Chevrolet C10, GMC Jimmy, or Pontiac Firebird with a matching transmission code, WS6712NA provides a direct-fit sealing solution based on the listed vehicle and transmission combinations.

This part cross-references common aftermarket listings for the same application.

What It Helps Address

• Transmission fluid seepage at the oil pump seal area
• Contamination entering the pump/seal interface
• Seal wear from age, heat, and fluid exposure
• Service issues during transmission rebuilds or resealing
• Fitment matching for front-position transmission applications

Installation Notes and Tips

Confirm the transmission code and seal dimensions before installation. Clean the housing bore and shaft surface thoroughly, and inspect for scoring, burrs, or wear that could affect sealing. Use proper installation tools to seat the seal evenly and avoid distortion. Verify the seal orientation and check fluid level after service.
