Just installed Autometer triple gauges, have a question.

I have been running my ScanGauge2 since I bought the truck so I could monitor
trans temps and etc.. I just finished installing my 3 Autometer gauges yesterday. I am curious as to which trans temp is MORE accurate, the Autometer trans side port or the ScanGauge2 reading from the OBDII port.
I have about a 15* difference. The scangauge2 is reading 164 and my Autometer is dead smack on 150 if not a tad lower.

Just curious if anyone else is running these with gauges. THANKS!!

Theres ALOT of opinions on this, some will say the sensor in the trans pan is the way to go, others will argue and say a test port or in the supply line to the transcooler is the way to go, but personally if your 15 degrees off and not hauling a heavy load, I wouldn't worry about it, even in the mud you will be ok. I believe the OBDII port reads it from a sensor in the trans so that would be the most accurate one.

I'd agree. Even though the test port is in the trans. It's better to know your hottest temp anyway

I made my Samsung SGH-I997 send this.
