Help keep transmission lubricant in and dirt and water out with the SKF Manual Transmission Seal, part number 27370. It is a direct-fit replacement for many Ford, Chevrolet and GMC trucks, among them the 1990-1993 GMC C6000 Topkick, 1990-1993 GMC C7000 Topkick and 1990-1993 Chevrolet C60 Kodiak. See the Buyer's Guide tab for the full list and engine details.
The seal body stays stationary in its bore while its lip rides on the rotating shaft, sealing the gap so lubricant stays inside the transmission. It is listed for both front and rear transmission seal positions, depending on the application.
SKF has been developing seals since it invented the first integrated shaft seal in 1928, and it continues to pioneer new designs and bonding techniques. Its seals are made to specific designs with premium materials chosen to suit both the application and its operating environment.
Signs this seal may need replacing include lubricant seepage or drips around the seal area, an oily film on the housing, or a transmission lubricant level that keeps dropping. Diagnose the source of the leak before replacing the seal.
