Re: WINNEBAGO TRANSMISSION HELP!!!
There is an ignition circuit that is supposed to power the shifter when the key is turned on. I would highly recommend going to www.allisontransmission.com and get one of their WTEC III troubleshooting manuals. There's a publications section of the website from which you can order one. If you're going to do your own troubleshooting, I think you'd really find it to be a big help. It won't have the vehicle wiring in it, but it will at least tell you what all the wires for the Allison are for.

Re: WINNEBAGO TRANSMISSION HELP!!!
I forgot to mention one thing. Don't be jumping power to circuits if you don't know what you're doing. Sensor power is normally a five volt output. If you jumped 12 volts input to it, you may damage something.....like your controller.

Re: WINNEBAGO TRANSMISSION HELP!!!
You are correct...
Allison Needs two signals. One is a direct power wire to battery voltage. The other is a wire off the Ign. side, this is the "wake up" signal to the Allison computer. Should be a fuse for both of these.
