Keep automatic transmission fluid where it belongs with the ATP Automatic Transmission Oil Pump Seal JO-127. This stationary seal sits at the front pump area of the transmission, where its lip rides against the rotating input/converter hub to contain fluid and keep it from weeping past the pump. It's a direct-fit replacement for a range of GM applications, including the 2006-2007 Buick Lucerne, 1994-2005 Cadillac DeVille, 1993 Cadillac Allante, 1993-2002 Cadillac Eldorado, 1993-2004 Cadillac Seville, 2006-2007 Cadillac DTS, 1995-1999 and 2001-2003 Oldsmobile Aurora, and the 2004-2005 Pontiac Bonneville — see the Buyer's Guide tab for the full list.
If the original pump seal is the source of a fluid leak at the front of the transmission, this seal replaces it. Signs it may need replacing include red transmission fluid seeping or dripping from the bell-housing/front pump area. One seal is used per application.
