Transmission Temperature Gauge (Automatic Transmission Only)
WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 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 via the SCP network. The instrument cluster micro-processor monitors the transmission temperature data and commands the gauge indication with a corresponding movement of the pointer.
