vehicles with trans temp readout
On Saturday I test drove a 2013 Jeep Grand Cherokee. I was pleased when the salesman showed me that the dash display could show transmission temperature as well as each tire's pressure. After seeing...

Like someone said, there is only one stock trans temp sensor. It isn't like the dash gauge connects to one sensor, and the OBDII port connects to another. Same one.
I, for one, trust that the mfgr installed the sensor in the location that is optimal for reading transmission temps, and calibrated the vehicle warning system according to temps that would be found at that location. As such, I do not know or do not care where the sensor was placed by GM. People a lot smarter than me know that readings of 255* at that location indicate a problem, and I'm willing to take that advice over someone who was working on 3-spd units under a shade tree back in 1975 (no offense intended to anyone on this board, but these new 6 spd units are different animals).
Re: different readouts, it would have to be due to the gauges. In my '06, it had an analog needle gauge that was quite small. So obviously it would have been hard to know if it was showing 197* or 203* or whatever. In my '10, the readout is digital, so obviously easier to read and get specific numbers. I would be curious to know if the scangauge gives different numbers than the digital dash readout.
