Tackle a transmission leak or a teardown with the Pioneer Automotive Industries Transmission Overhaul Kit 750021, a pre-packaged kit of gaskets, seals and other parts for resealing the unit after disassembly. It is cataloged for 1970s and early-1980s Ford and Mercury vehicles, including the 1970-1976 Ford Torino, 1971-1980 Ford Pinto, 1973-1977 Ford Bronco, 1974-1981 Mercury Cougar and 1975-1981 Ford Granada. See the Buyer's Guide tab for the full list of vehicles and engine details.
Four kit levels: Pioneer offers its transmission repair kits in Overhaul, Banner, Master and Super Kit levels. This listing is the Overhaul Kit, a premium pre-packaged option for transmission service work.
What's inside: Gaskets, seals, O-rings, a pan gasket, rubber lip seals, metal clad seals, sealing rings and other components specific to the application.
Repair it addresses: A leaking transmission, or any internal service that requires disassembling and resealing the unit.
Pre-packaged: The kit's parts come packaged together in a single kit.
Seals and gaskets keep transmission fluid inside the case and between internal circuits. Over time they can harden, shrink or crack. Signs these parts may need replacing include fluid drips under the vehicle, seepage around the pan or shaft seals, and a fluid level that keeps dropping. If worn seals or gaskets are the source of the leak, this kit replaces them during the overhaul. Diagnose the cause before you start, and follow the vehicle's service information for the procedure and specifications.
