Installation Notes and Tips
Verify the transmission type and catalog notes before installation. Several applications list specific requirements such as ADJ 15-16, EDA 1.95, dual blue, blue, or red stripe configurations, and some rows note limited transmission coverage such as THM180, THM180C, 3L30, 3L80, THM425, or THM475/M40. Confirm the original valve style, thread type, and transmission family against the vehicle before ordering. Part number 747020 should be matched to the exact application listed in the fitment table.
Quality Assurance
Pioneer Transmission Components markets these parts as exact-fit replacement components with no compromise in application matching. That makes 747020 a practical choice when you need a direct replacement modulator valve for the listed Chevrolet Tracker, Geo Tracker, and related GM automatic transmission applications.
