Good To Know

Q: Why do I need to seal the speedometer port? A: An open port allows transmission fluid to leak out and permits dirt and moisture to enter, which can cause severe internal transmission damage over time.

Q: Does this plug require specialized installation tools? A: No, this plug can usually be tapped into place using standard hand tools to ensure a tight, secure fit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
