4R70W Transmission Front Pump Seal Kit W/Gasket, Oring & Seal

Stop transmission fluid leaks at a critical point with the Keliejnese Front Pump Seal Kit for the Fo rd 4R70W transmission. This targeted repair kit provides the essential components needed to reseal the front pump assembly, a common source of automatic transmission fluid (ATF) leaks that can lead to low fluid levels, pressure loss, and potential damage. The kit includes a precision-engineered gasket, a high-quality O-ring, and a durable lip seal, all designed to work together and create a reliable, leak-proof barrier between the torque converter and the pump housing. Over time, the original seals can harden, crack, or wear, compromising the seal and causing messy drips or performance issues. Our replacement parts are made from materials specifically formulated to resist heat, pressure, and exposure to ATF, ensuring a long-lasting repair. Whether you’re performing a scheduled service, addressing a known leak, or as part of a larger rebuild, this straightforward kit gives you exactly what you need to restore a tight seal. Installation is manageable for experienced DIYers. Protect your transmission’s health and performance by tackling front pump leaks proactively.
