ATP Parts B-259 Transmission Filter

Transmission Oil Filter for GM Applications

ATP Parts B-259 is a premium replacement transmission oil filter built to keep transmission fluid cleaner as the unit accumulates normal wear debris. Clean fluid helps protect the valve body and other critical internal components from clogging, which supports smoother operation and helps reduce avoidable transmission repairs.

This ATP Parts Premium Replacement filter is made for a wide range of Chevrolet, Pontiac, Saturn, and Oldsmobile vehicles, including Chevrolet HHR, Malibu, Cobalt, and Cavalier applications. If you are servicing a 2006-2011 Chevrolet HHR or a 2005-2010 Pontiac G6, B-259 is the transmission filter specified for those applications.

Detailed Description

ATP Parts B-259 is a transmission filter designed for routine maintenance on GM vehicles that use this application. Over time, transmission fluid carries fine debris from normal wear, and the filter helps capture that material before it can circulate through the transmission. Regular filter replacement is a practical service step for maintaining fluid cleanliness and helping extend transmission life. This part number B-259 is used across multiple Chevrolet, Pontiac, Saturn, and Oldsmobile models, including Chevrolet Malibu, Pontiac Grand Am, and Saturn Vue applications.

ATP Parts Premium Replacement products are positioned as direct-fit service parts for common repair and maintenance needs. For some applications, such as certain 2011 Chevrolet Malibu and several Saturn L-series models, the notes indicate the OE pan gasket is reusable and a separate pan gasket reference may apply.

What It Helps Address

• Dirty transmission fluid from normal wear
• Debris buildup that can restrict fluid flow
• Valve body contamination
• Internal component clogging
• Service intervals where the transmission filter is due for replacement

Installation Notes and Tips

Install during transmission service with the pan removed and the fluid drained. Verify the vehicle application by year, make, and model before ordering, since B-259 covers multiple GM platforms. For listed applications with reusable OE pan gasket notes, inspect the existing gasket carefully and replace it only if condition requires it. Always follow the vehicle service procedure for filter and fluid replacement.

Quality Assurance

ATP Parts Premium Replacement transmission filters are built for maintenance service where clean fluid and proper filtration matter. This part number B-259 is specified across confirmed GM fitments for Chevrolet, Pontiac, Saturn, and Oldsmobile applications.
