Detailed Description

ATP Parts B-331 is a transmission filter kit engineered for vehicles that rely on clean automatic transmission fluid to protect internal components. Over time, normal wear can create debris that collects in the transmission pan and filter. Replacing the filter during service helps reduce contamination that can restrict fluid passage and affect valve body operation. This Premium Replacement kit is a practical choice for Toyota 4Runner and Tacoma service, as well as other listed Toyota and Lexus models that use the same application.

ATP Parts B-331 also cross-references Bosch 15503 and Dorman - HELP 58136 for the same application.
