Grand Cherokee 2WD V6-3.7L (2008)
Temperature Warning Indicator - A/T: Description and Operation
Description
DESCRIPTION
A transmission over-temperature indicator is standard equipment on all instrument clusters. However, on vehicles not equipped with an optional
automatic transmission, this indicator is electronically disabled. The transmission over-temperature indication appears within the reconfigurable dot
matrix Organic Light Emitting Diode (OLED) display unit. The transmission over-temperature indicator consists of a textual TRANSMISSION OVER
TEMP message which appears in place of the compass/trip computer information in the dot matrix display.
The dot matrix OLED is soldered onto the cluster electronic circuit board, and is visible through a window with a smoked clear lens located on the lower
edge of the tachometer gauge dial face of the cluster overlay. The dark lens over the OLED prevents it from being clearly visible when it is not
illuminated. The transmission over-temperature indicator textual message appears in the same white color and at the same lighting level as the
compass/trip computer information when it is illuminated by the instrument cluster electronic circuit board.
The transmission over-temperature indicator is serviced as a unit with the OLED in the instrument cluster.
