Transmission Temperature Gauge (Automatic Transmission Only)
WARNING: This page is about a different car, the 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The instrument cluster receives the transmission temperature information from the PCM over the communication network. The instrument cluster monitors the transmission temperature data and commands the gauge indication with a corresponding movement of the pointer.
