Help keep automatic transmission fluid where it belongs with the SKF Automatic Transmission Oil Pump Seal / Auto Trans Seal 17458. This front seal is a direct-fit replacement for the listed applications, including the 1985-2005 Chevrolet Astro, 1988-1999 Chevrolet C1500, 1995-2009 Chevrolet Tahoe, 1999-2013 Chevrolet Silverado 1500, 2002-2011 Cadillac Escalade and 2004-2007 Buick Rainier. It also fits many more Chevrolet, GMC, Cadillac, Pontiac, Buick and Oldsmobile models. The part is cataloged under both names: automatic transmission oil pump seal and auto trans seal.
The seal installs at the front of the transmission's oil pump. Its case stays stationary while its lip rides on the rotating torque converter hub. This helps retain transmission fluid and keeps dirt and water out.
- Steel garter spring: The garter spring is made from cold drawn steel wire for superior fluid retention.
- Rigid metal case: The body is formed from deep drawn sheet steel, creating a rigid, stress-resistant metal case.
- Contaminant protection: It is designed to give superior protection against dirt and water.
- Correct fit: SKF builds it with a high-quality, tested design and materials for correct fit.
SKF invented the first integrated shaft seal in 1928 and has kept developing new designs and bonding techniques since then. Each SKF seal is made to a specific design using premium materials selected for its application and environment, keeping lubricants in and contaminants out.
Signs this seal may need replacing include transmission fluid dripping from the front of the transmission or between the engine and transmission, and a dropping fluid level. Other seals can leak in the same area, so confirm the leak source before replacing.
