Wix 58140 Transmission Filter Kit

Wix 58140 Transmission Filter Kit

The Wix 58140 transmission filter kit is built for automatic transmissions that need clean, controlled fluid flow. Its application-specific filtration media and sealed construction help keep unfiltered fluid from bypassing the filter, supporting consistent transmission service on select Nissan models.

Key Features

• Automatic transmission filter kit for service applications
• Application-specific filtration media helps capture contaminants in transmission fluid
• Lock-seamed, sealed assembly helps prevent bypass around the filter media
• Includes sealing gaskets designed for modern transmission fluids
• Closed top design
• Light-duty construction

Detailed Description

Wix 58140 is an automatic transmission filter kit engineered for service work where fluid cleanliness matters. The filter uses a sealed, application-specific design so fluid is directed through the media rather than around it. That construction supports proper filtration during routine maintenance on vehicles such as the Nissan Altima, Nissan Maxima, and Nissan Quest. This part cross-references ATP B221 for the same application.

Compatible With 2002-2006 Nissan Altima, 2004-2007 Nissan Maxima, 2004-2009 Nissan Quest, and 2013 Nissan Altima. The Wix 58140 part number is also a useful reference when matching transmission service components for these applications.

What It Helps Address

• Transmission fluid contamination from normal wear
• Restricted fluid flow caused by a clogged filter
• Poor filtration from worn or damaged service parts
• Fluid bypass around the filter media
• Service issues tied to aging transmission gaskets

Installation Notes and Tips

Verify transmission type and filter style before installation. Inspect the pan, sealing surfaces, and fluid condition during service, and replace the gasket only with the correct application-specific component. Follow the vehicle service procedure for torque values, fluid level checks, and refill specifications.

Quality Assurance

Wix transmission filter kits are built with sealed assemblies and application-matched sealing components to support complete filtration during service. The 58140 is designed as an OE-style service part for select Nissan automatic transmissions.
