ATP Parts TF-109 Transmission Filter Kit

ATP Parts TF-109 is an OE Replacement transmission filter kit built to keep transmission fluid cleaner as it circulates through the system. Clean fluid helps reduce debris buildup from normal wear, which can protect the valve body and other critical internal components from clogging.

Compatible with select Toyota 4Runner, Toyota Pickup, Mitsubishi Montero, and Mitsubishi Montero Sport applications, this ATP Parts TF-109 transmission filter kit supports routine service on high-mileage and daily-driven vehicles. It is a practical choice for drivers looking for an OE-style transmission filter replacement for 1984-2000 applications.
