Detailed Description

ATP Parts B-129 is built for routine transmission service on vehicles such as the Nissan Frontier, Nissan Pathfinder, Nissan Xterra, INFINITI QX4, Suzuki Equator, Mazda MPV, Mazda 929, Mazda B2600, Nissan Pickup, Nissan D21, and Nissan NV2500. The Premium Replacement line focuses on service parts that match the needs of common maintenance intervals, and this filter kit is made to help keep transmission fluid clean as normal wear creates debris inside the unit. Regular filter replacement can reduce contamination that contributes to clogged passages, restricted valve body movement, and premature transmission wear.

• Debris buildup that can clog internal transmission passages
• Restricted valve body operation caused by contamination
• Service-related transmission performance concerns
