Detailed Description

SKF 17458 is an automatic transmission seal engineered to help maintain proper fluid control at the front of the transmission. SKF has a long history in seal design and bonding methods, and this seal reflects that experience with application-specific construction and premium materials selected for the operating environment. The result is a seal sized for the shaft and housing dimensions listed here, with the Vamac sealing surface helping support dependable contact where transmission fluid retention matters most.

What This Seal Helps Address

• Transmission fluid seepage at the front seal area
• Contamination entering the transmission through a worn seal
• Leak-related low fluid condition during service intervals
• Seal wear from age, heat, and fluid exposure
• Fitment issues when replacing an aging front automatic transmission seal

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the transmission case and shaft. Inspect the sealing surface and surrounding components for scoring, burrs, or wear that could shorten seal life. Clean the bore thoroughly and install the seal squarely to avoid distortion. For vehicles such as Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Tahoe, confirm the transmission family and front seal location against the vehicle’s service information before assembly.

SKF manufactures seals to specific designs using premium materials and controlled production standards. The brand’s seal engineering heritage dates back to the first integrated shaft seal in 1928, and SKF products are built to support long service life and safe operation in demanding automotive environments.
