Help keep automatic transmission fluid where it belongs with the ATP Automatic Transmission Dipstick Tube Seal / Filler Tube O-Ring, part number JO-16. It fits many vehicles, among them the 1988-1990 Chevrolet C1500, 1988-1990 Chevrolet K1500 and 1962-1964 Ford F-250, and is a direct-fit replacement for the listed applications.
ATP calls this part an automatic transmission filler tube O-ring seal. It is also cataloged as an auto trans dipstick tube seal, so you may see it under both names. It seals the filler/dipstick tube at its connection to the transmission and helps keep fluid from seeping out at that joint.
Signs this seal may need replacing include transmission fluid wetness or drips around the base of the filler tube. Other components can also leak, so confirm the source before you replace parts. See the Buyer's Guide tab for the full list of applications.
