Help keep transmission lubricant sealed in at the output shaft with the SKF Automatic / Manual Transmission Output Shaft Seal, part number 16143. This right-side seal is a direct-fit replacement for the listed applications and fits many vehicles, among them the 2001-2014 Hyundai Elantra, 1999-2010 Hyundai Sonata and 2001-2010 Kia Optima.
The seal body stays stationary in its bore while its lip rides on the rotating output shaft. It holds lubricant in and helps keep dirt and water out. The seal is listed under both the automatic and manual transmission output shaft seal names.
- Rigid metal case: The body is made from deep drawn sheet steel, which gives it a rigid, stress-resistant case.
- Garter spring: The spring is made with cold drawn steel wire for fluid retention.
- Contaminant protection: The seal is designed to protect against dirt and water.
- Correct fit: It is manufactured with a tested design and materials intended for correct fit.
SKF invented the first integrated shaft seal in 1928. Since then it has kept developing new seal designs and bonding techniques. Its seals are made to specific designs using premium materials chosen for each application and its operating environment.
Signs this seal may need replacing: fluid seeping or dripping around the right-side output shaft, or a transmission fluid level that keeps dropping. Diagnose the source of the leak before replacing parts.
