I use a OBDII adapter and the torque Andorid app. I have real time access to all information (Trans, engine temp) real mpg.. etc etc
As well as full time mapping and tracking via GPS. I can see, over a trip, overlaid on google maps where my engine was X or my trans was X.
My buddy had a scan gauge and dumped it as soon as he saw mine.
If you have an android phone, you have a device with about 100 times the cpu power of the scan gauge. All you need is the physical connector to the OBDII.....
This guy:
Buy.com - ELM327 OBDII Bluetooth Diagnostic Interface Transceiver Adapter For Car Short / Long Term Fuel Trim
Is exactly what I bought. Only from Amazon. Too lazy to find it on there. It works perfectly. All it is, is a OBD to Blutooth convertor. Your phone app (torque) for android does ALL the work.
Do you have a v8?
If you have a v6 can you let me know the code for the trans temp.
It works if I use it on my friends ford and then plug it into the 4R but it doesnt show trans temp if i do a direct plugin

1) There are two temperature sensors in the 09 AT, "A" and "B". They read the oil temperature, as one would expect
2) The sensors present the temp as an electrical resistance to the ECU, varying from 79Ω to 156kΩ and the ECU converts it to a temp value in °C
3) The Toyota Techstream tool reads the temps from the ECU through the OBD interface, so it must possible for us to do so, too!
4) The ECM speaks ISO 15765-4 (and possibly SAE J1987, they're both mentioned in the manual)
5) The "B" sensor is placed directly before the oil cooler inlet pipeline, not mentioned where the "A" sensor is
6) The ECU considers the valid temperature ranges to be -40°C to 215°C (-40 to 419F)
