Built for transmission fluid control

Wix part number 58978 is an automatic transmission filter kit engineered for service on select Nissan and INFINITI vehicles. The filter construction is designed so fluid passes through the filtration media rather than around it, while the sealed assembly and application-specific sealing components help maintain proper fluid control during transmission service. This makes the Wix 58978 a practical choice for owners servicing a Nissan Pathfinder, Nissan Xterra, or INFINITI QX4 with the correct transmission application.

Common issues this service kit can address

• Restricted transmission fluid flow caused by a dirty or clogged filter
• Contamination in automatic transmission fluid
• Poor sealing at the transmission filter or gasket interface
• Service-related fluid leakage after transmission maintenance
• Reduced filtration performance in high-mileage automatic transmissions

Installation notes and tips

Verify transmission type and application before installation, especially on vehicles with specific transmission codes such as the RE4R01A listed for certain Nissan 300ZX models. Clean the transmission pan and mating surfaces thoroughly before installing the new filter and gaskets. Confirm the filter seats correctly and that all sealing surfaces are aligned before refilling with the specified transmission fluid.
