Detailed Description

Wix 58545 is an automatic transmission filter kit engineered for vehicles that require precise filtration and dependable sealing during transmission service. The filter design uses application-specific media and sealed assembly construction to help prevent unfiltered fluid from circulating through the transmission. This matters on vehicles such as the BMW 330i, BMW X5, Cadillac CTS, and Pontiac G8, where clean fluid and proper pan sealing are important to transmission performance. This part cross-references Purolator P1315 for the same application.

What It Helps Address

• Transmission fluid contamination from worn or clogged filter media
• Poor sealing at the filter or pan interface
• Service issues on deep pan automatic transmission applications
• Reduced fluid flow caused by a restricted filter
• Maintenance needs on BMW 323i, BMW 525i, and Cadillac SRX automatic transmissions

Installation Notes and Tips

Verify transmission code and pan style before ordering, especially on BMW applications with 5L40E or 5K40E notes. Confirm the vehicle uses a deep pan filter configuration and match the original part number when servicing BMW, Cadillac, Pontiac, or Saturn models. Clean the pan and mating surfaces thoroughly before installation to support proper sealing.

Quality Assurance

Wix transmission filter kits are built with sealed, lock-seamed construction and sealing components matched to modern automatic transmission fluids. The 58545 is designed as a service replacement for select OE applications, including BMW and GM platforms.
