I have all the wiring schematics (the Allison tech printed them out for me). Pin 6 on the shift pad is a "wake up" wire. Pins 1 and 7 are hot all the time in the shift pad, and voltage to 6 wakes up the shifter. This is confirmed by the mobile tech and Allison on line. The other two connectors that work on the pad are communication from the computer.
You don't want to take your shift pad out. I had to call Newell and it is quite a task.
The local Allison dealer doesn't have a new, or old shift pad. They can order one in (at over $3k).
Yes, that was the first thing the tech checked. The two fuses are good. The six relays are all the same. He took them out and measured each one. All good. Then we placed them all in different locations as a second test.
