Detailed Description

Wix 58995 is a transmission filter kit engineered for automatic transmission service where clean fluid and proper sealing are critical. The filter design uses application-specific media and sealed assembly construction to help maintain filtration integrity inside the transmission. This matters for vehicles such as the Mazda Protege, Mazda 323, Ford Escort, Mercury Tracer, Kia Sephia, and Kia Spectra, where transmission fluid condition directly affects shifting performance and internal wear control. This part cross-references Motorcraft FT123 for the same application.

The kit is built around a closed-top automatic transmission filter style and includes sealing gaskets matched to today’s transmission fluid formulations. If you are servicing a high-mileage automatic transmission or replacing a clogged filter during routine maintenance, Wix 58995 provides the correct service format for the listed applications.
