InMotion WS4532N Manual Transmission Output Shaft Seal

Manual Transmission Seal Overview

The InMotion WS4532N is a manual transmission output shaft seal built for applications using New Process 3500 and 3550 transmissions. It uses a polyacrylate sealing material and precise dimensions to help maintain a tight barrier at the shaft and housing interface.

Compatible With Chevrolet Silverado 1500, GMC Sierra 1500, Jeep Wrangler, and other listed applications, this seal is focused on controlling fluid retention and keeping contaminants out of the transmission assembly. The WS4532N is a fitment-specific replacement for vehicles that require the correct seal size and transmission match.

Key Features

• Polyacrylate construction for sealing performance in transmission service.
• 1.375 inside diameter and shaft diameter for application-specific fit.
• 3.549 outside diameter and 3.542 housing bore dimensions for proper seating.
• Fits New Process 3500 and New Process 3550 transmission applications.
• Part number WS4532N for accurate ordering and catalog matching.

Detailed Description

WS4532N is engineered as a transmission output shaft seal for a wide range of Chevrolet, GMC, and Jeep applications. Fitment includes 1991-2007 Chevrolet Silverado 1500 Classic, Silverado 1500, Blazer, S10, S10 Blazer, K1500, K2500, and K3500; 1991-2007 GMC Sierra 1500 Classic, Sierra 1500, Jimmy, Sonoma, K1500, K2500, K3500, and S15 Jimmy; plus 2000-2004 Jeep Wrangler, all with the specified New Process transmission. The seal dimensions and material selection support a secure interface where the shaft passes through the housing, helping reduce leakage and contamination at the transmission opening. If you are replacing a worn transmission output shaft seal on a Chevrolet Silverado 1500, GMC Sierra 1500, or Jeep Wrangler, WS4532N provides the correct catalog-specific match for the listed applications.

What It Helps Address

• Transmission fluid seepage at the output shaft area.
• Contaminant entry through a worn or damaged seal.
• Seal wear that can lead to driveline fluid loss.
• Improper sealing from an incorrect size or transmission match.

Installation Notes and Tips

Verify the transmission type before ordering, since fitment is tied to New Process 3500 or 3550 applications. Confirm shaft and housing dimensions against the original seal during service. Clean the sealing surface and inspect the shaft for wear or scoring before installation.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and high-quality materials for consistent sealing performance in transmission service. Part number WS4532N should be matched to the vehicle and transmission listing before installation.
