Automatic Transmission Torque Converter Seal

National 710889 is an automatic transmission torque converter seal built for metric applications that require a precise shaft and housing fit. It uses a fluoro-elastomer sealing material and a clockwise-spiral lip design to help maintain sealing performance in the transmission assembly.

Compatible with a wide range of Buick, Chevrolet, GMC, Pontiac, and Saturn vehicles, this seal is a direct-fit service part for many 2008-2019 applications. If you are replacing a leaking torque converter seal on a Chevrolet Cruze, Equinox, or Malibu, National 710889 is built to match the listed dimensions and OE-style service requirements.
