Detailed Description

FAG SS2457 is engineered for transmission sealing service where dimensional accuracy and material selection matter. The silicone sealing element, spring tension, and auxiliary lip work together to help retain transmission fluid at the output shaft while supporting consistent sealing performance in demanding driveline environments. This part number is listed for numerous GM front-wheel-drive and transaxle applications, including Buick Century, Buick Regal, Buick LeSabre, Cadillac DeVille, Chevrolet Lumina, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix models.

What It Helps Fix

• Transmission fluid leaking from the output shaft area
• Fluid seepage around the left-side transaxle seal
• Contamination entering the sealed transmission opening
• Seal wear caused by age, heat, and mileage
• Loss of sealing integrity during drivetrain operation

Installation Notes and Tips

Verify the vehicle year, make, model, and left-side application before ordering. Match the seal dimensions to the original part and inspect the shaft surface for scoring, corrosion, or wear before installation. Clean the sealing bore thoroughly and install the seal squarely to avoid distortion. For best results, confirm the transmission code and application notes on vehicles such as Buick Century, Cadillac Fleetwood, and Chevrolet Impala before service.
