Good To Know

Q: Can I use these with AN hose ends instead of factory quick connects? A: Yes, the 6AN threads are made to accept standard aftermarket AN hose ends, letting you build custom cooler lines. Factory quick connect fittings will not attach to this plate.

Q: Do these work on both cooler ports? A: The adapter is made for the transmission case cooler line connection point, so confirm which port you are plumbing on your 6L80E, 6L90E, or 8L90E before ordering. Order the quantity you need for each port.

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