Trans Temp Indicator: Description
A transmission over-temperature indicator is standard equipment on all instrument clusters. This indicator is located in the center of the speedometer, in the area above and to the right of the speedometer needle hub.
The transmission over-temperature indicator consists of a stencil-like cutout of the International Control and Display Symbol icon for "Transmission Temperature" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. A red Light Emitting Diode (LED) behind the cutout in the opaque layer of the overlay causes the icon to appear in red through the translucent outer layer of the overlay when the indicator is illuminated from behind by the LED, which is soldered onto the instrument cluster electronic circuit board. The transmission over-temperature indicator is serviced as a unit with the instrument cluster.
