ATP Automatic Transmission Extension Housing Seal P/N:JO-57
Keep automatic transmission fluid where it belongs with the ATP Automatic Transmission Extension Housing Seal JO-124. This seal seats in the transmission's extension housing and rides against the rotating output shaft, sealing the point where the shaft exits the housing so fluid stays inside and contaminants stay out. It installs as a direct-fit replacement across a broad list of applications, including the 2002-2005 Chevrolet Avalanche 2500, 1996-2009 Chevrolet Express 2500 and Express 3500, 2001-2006 Chevrolet Silverado 2500 HD, 2000-2007 Chevrolet Suburban 2500, 2002-2003 Cadillac Escalade EXT, and 2000-2007 Bentley Arnage — see the Buyer's Guide tab for the full list of 187 applications.
Signs the original seal may need replacing include automatic transmission fluid seeping or dripping at the rear of the transmission where the driveshaft connects, or wet residue on the extension housing. If a worn extension housing seal is the cause of the leak, this ATP seal replaces it.
