If you’re running a fanned transmission cooler on your 6R80 or 10R80 setup, you might be powering the fan with constant 12V — which means it’s running even when the fluid’s still cold. That’s not ideal. This 180° thermal switch from PBH is the simple fix.

Designed to thread right into any -8AN line in your transmission cooling system, the switch automatically powers your fan on at 180°F and turns it off at 165°F — giving you smart, efficient cooling without the need for manual control.

Why you’ll want this:

  • Helps your transmission warm up properly before the fan kicks in

  • Protects your fan and keeps your system running more efficiently

  • Simple inline install — no special tools or wiring kits required

  • Compatible with any -8AN cooling line

Specs:

  • -8AN Male to -8AN Female Fitting

  • Fan ON at 180°F / OFF at 165°F

  • For use with 12V power systems

Works on all 2015-2023 Mustang 6R80/10R80 transmissions
