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

Restore a leak-free, pressure-tight seal to your Fo rd 4R70W transmission with the Keliejnese Front Pump Seal Kit. This targeted kit provides a precise solution for one of the most common sources of automatic transmission fluid (ATF) leaks: the front pump assembly. Engineered for reliability, the kit includes all the high-precision components needed to effectively reseal the critical interface between the torque converter and the pump housing. Inside, you’ll find the essential front pump bushing, a durable gasket, a high-quality O-ring, and a precision lip seal. Over time, these components can wear or degrade, leading to fluid loss, which in turn can cause slipping, overheating, and a drop in hydraulic pressure. Our kit uses materials specifically formulated to resist ATF and withstand the heat and pressure within the transmission. Whether you’re performing a full rebuild, a targeted repair during a fluid change, or addressing a known front seal leak, this all-in-one set simplifies the process. Stop the drip, protect your transmission from damage due to low fluid levels, and maintain the smooth, reliable shifting your Fo rd is known for.
