• Delayed engagement from a worn converter
• Excessive vibration related to converter wear
• Drivability issues tied to incorrect spline or pilot fitment

Installation Notes and Tips

Verify the converter codes, 20-spline count, 1.257-inch pilot diameter, and 6-pad mounting pattern before installation. Confirm the transmission application against the vehicle fitment list, especially for Toyota Tacoma, Toyota 4Runner, Lexus GS300, and Toyota Tundra models. Proper fluid fill, clean mating surfaces, and correct alignment during installation are important for reliable operation.
