Allison transmission blowing fuses

[Mattaniah]

I have a 2015 fleetwood Excursion 35e - Cummins engine with Allison transmission. The transmission shift inhibit light came on last week on the way to where we are now. Today as I went to leave the state park, both transmission fuses blew when I attempted to shift into gear.

I’ve opened up the whole dash - all the wires apear to be in good condition.

Help! I’m stumped.

Thanks!

The Allison transmission will communicate through the control panel. Bring transmission up to temperature then press the UP and DOWN arrows simultaneously. There is a 2 minute countdown and you should get any diagnostic messages regarding fluid levels or other information.
Press and hold the Mode switch for approx 3 seconds to get codes.
