6L80 / 6L90 / 8L90 / 10L90 Cooling System Bypass Upgrade Kit (2014-Up, STL010)

About This Product

If you're running a 2014 or newer GM with a 6L80, 6L90, 8L90, or 10L90 transmission, you know heat is the enemy.

This unbranded cooling system upgrade kit (part STL010) helps keep things chill.

It's basically a bypass solution that improves flow and cooling, which can save your trans from early death.

Made from metal, comes with a gasket, and it's a direct fit for 4WD setups.

No core charge, no messing around.

Brand new in the box—maybe just a plain box, but it's the part that counts.

If you're towing, racing, or just want your transmission to last, this is a solid mod.
