Question: Transmission Fuild Temp

Hey all. I've seen it in a few thread about changing your transmission fuild, there is a little gadget folks have plugged in that displays the fluid temperature. What is that gadget(s)?
I have a 2008 sr5 rwd if it matters.

 

Are you reffering to something like a Scan Gauge 2?
I dont know how much that relates to changing your fluid. But it is a good way to monitor it's temps among other things

 

He's probably referring to using the ScanGauge temperature reading to set the fluid level after changing.

The first time I used the ScanGauge for that purpose @xx8xx , I would actually double-check the fluid level setting temp with the OBD jumpering method. Since the 5.7L setting temperature range is 99-111 degrees, the fluid temperature might blow through that range this time of year before it even registers on the ScanGauge.

 

According to some and probably the manual, the trans fluid needs to be a certain temperature to ensure an accurate level measurement (i think). And yeah. That looks like one of the gizmos. Thanks! I was looking for a code reader that maybe did it too, but no luck so far.

 

Ooohh I didn't know that it was used for that

 

You had a head start on me. I didn't even know what it was.

 

The ScanGauge is the simplest and easiest to use code reader that gives you transmission temperature. You plug it into the OBD port, and the corded head gives you transmission temperature (still may require some programming).

There are many code readers, and there are several threads here on how to set up your phone or pad with an app to read transmission temperature and other engine parameters provided by OBD using Blue Tooth or WiFi. The most complicated of these is OBD Fusion or Torque Pro. Do a search if you want to wade in deeper.

 

Good info thanks @JohnLakeman and @Johnders2586
