Thought I'd pull up this older thread to ask a question about the scan gauge II. I just replaced my original scan gauge with a scan gauge II. One of the reasons for the replacement was the ability to read the transmission temp. with the the new gauge. My MH is on a 2013 Ford E450 with the V10 engine. I've tried the four different settings with the X gauge commands,but can't get any transmission temp reading with any setting. Has anyone been able to get a transmission temp. reading on a newer Ford V10 ? According to my mechanic the trans. temp does come through the OBD II connection port.
