Cadillac SRX First Generation Forum - 2004 - 2009 Discussion, Checking transmission temps while driving in Cadillac SRX Forums; So how do I get my transmission temperature while I drive?
Scanner, Bluetooth dongle and app?
I want to see ...
I can't get a transmission temperature reading for my '08 SRX V6 with my Dashhawk, either.
I've been told that the DIC will indicate too high a temperature reading, but have not a clue where it is getting the info.

Re: Checking transmission temps while driving
I'm using one of their gauges on my 07 5 speed. Had to send it back a couple times but they were good to work with. I tried a scanguage II (www.scanguage.com) but could never get it to read trans. temp. Maybe they've updated the software. Might be worth an inquiry.
Nope, ScanGauge won't read transmission temps. For most units the sensor is a go-no go affair - temp exceeds some value depending on transmission model and the sensor does one or more things - sets a message, sounds a warning, or turns cooling fans to fast (Northstar FWD) - and the trip temp is 304 degrees F (from the GM service manual).
Fluid temps of 225 are perfectly normal - and the new (2006) DEXRON-VI synthetic can run pretty hot -safely. In most vehicles the transmission cooler is in the return tank of the radiator, so it gets the benefit of the "cool" end of the radiator.
