Trans Temp Gauge
 

Drive an 02 1500 Z71 5.3. I want to put in a trans temp gauge. I see that you can just replace the entire dash unit that would have the trans temp gauge built in but is there a cheaper way to do it. I would like to do this butdon't know if anything has to be reprogramed. I found one on Ebaybut that speedometer goes up to120 and mine only 100. Is there a way to wire up a gauge into the wiring harness for a pilar mount. That might be easyer.

Also:
I look at my manual and see that the Message Center will tell you when the Trans Temp is too hot. Anyone know what temp makes this light come on.

Thanks
