Does it read trans temp? If your parts store still has them, PM me to work a purchase out please.

It doesn't do tranny temp.
If you go on princess auto website you can pull up the manual for it and it tells you everything it does.
The scangauge2 has a update that now does tranny temp, it also can tell you hp but I've heard from other forums the hp is a estimate and it told someone they had over 400 hp when the most they had was 200..other than that the scanguage is a better tool than the maxitrip, but I could do 90% of the same stuff as it and for less than a quarter of the cost...I m happy with this tool.
The screen is bright so I'm gonna put a little tint on it.. I can't find the backlight adjustment if there even is 1.
