    Does OBDII measure the automatic transmission's temperature?

    If so, what brand(s) of scan tool or scan software are capable of reading this data stream?

    I have been towing trailers as of late, and it has piqued my curiosity as to what my temps are. I enjoy having accurate data to monitor mechanical systems while I'm operating them, but I don't have any for the transmission temp and it seems that the ECM would be a logical source if I want accurate information without the difficulty of adding and properly locating an aftermarket sensor and gauge.

    I heard that Scangauge II will update their software to monitor AT temps, also can upgrade old units.

    FWIW, My snap on scanner with toyota specific software does not seem to have trans temp. I really wish it did. If there is something out there that will I'll probably get it. Obviously its dependent on if the vehicle has that sensor or not.
  4. The latest version of Scangauge is suppose to monitor AT temps, I don't know if it is complete yet, last I heard there had a minor bug to fix.

    My Scangauge II is in the mail but my question is:

    Will it show engine oil pressure ?
