That site has really good Allison version ID info. Dan mentioned his truck is 2007. Gen 5 apparently came out later. If Allison is called they might need that info.
Looks like gen 4. Has the mode light but gen 5 does not have mode tight.
Dan, looking back several days, that picture with 4 volts in red circle could be important clue. With failure back, is that point at low voltage again? You said it was supposed to be 12v? If so then tracking the source could find the gremlin that's killing the voltage.
Allison tech found that the output speed sensor (OSS) was shot. From the error codes we were researching, plus the non-functioning speedometer, that seems to make sense. Part is on order, earliest arrival in 48 hours. He was not able to get communications with the transmission control module (TCM), using his diagnostics tester plugged into the test port by the driver's knee. We'll keep pursuing that issue; I'd feel better about getting a full diagnostics read on this transmission.Got a tech on site to check out the Allison.
