Last week I picked up an OBD2 bluetooth scan tool - BAFX ELM 327 Bluetooth from Amazon. About $30 shipped. I also got the Torque Pro android app and loaded it on my Motorola Droid 2 phone ($5). My goal has been to find something that will provide good quality gauge information using the OBD2 signals, but have been especially focused on the automatic transmission temperature reading. To date few standard OBD2 readers seem to be able to handle the tranny temp. ScanGauge 2 seems to with some programming, but I wasn't all that interested in the SG2 and the bluetooth seemed like a slick way to go.
This weekend I towed my ATV for some R&R and took the opportunity to see if Torque Pro would give me what I wanted. I was very happy to see that there was a reading of the transmission temperature. In watching the readout, it appears to be monitoring and reporting the trans temp. I watched closely when going up hills, switching between OD of and off, and tracked engine load, coolant temp, rpm, and the trans temp to see how they interacted and to see if what was being reported as trans temp was actually a trans temp and not some other signal.
It appears that Torque Pro is reporting the trans temp and required no special setup or equations. I generally ran at 60 to 65 C (140 to 150 F). When the torque converter unlocked, I clearly saw temperatures rise to 75 to 80 C (167 to 176 F). I'm running a transmission cooler in line with the radiator, for what it's worth. Did most of the trip with OD off to prevent the transmission from unlocking the torque converter. Coolant temps increased with load and was especially noticeable in OD.
My main purpose of this post was to report what appears to be a very successful use of Torque Pro. For the total price (about $35 delivered), I've got customizable gauges and can track the auto tranny temp. I'm now considering getting a smaller Android tablet to take over the gauge and gps functions and get a screen that's a good bit bigger than my phone.
Can't promise how this might work for others. My 4Runner is a 2002, YMMV.
