Trans Temp Indicator: Description
A transmission over-temperature indicator is standard equipment on all instrument clusters (Fig 1 ). However, on vehicles not equipped with an optional automatic transmission, this indicator is electronically disabled. The transmission over-temperature indicator is located on the left side of the instrument cluster, to the left of the fuel gauge. The transmission over-temperature indicator consists of a stencil-like cutout of the words "TRANS TEMP" 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 "TRANS TEMP" text 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.
