Trans com failure?
On a recent trip I got this message "TRANS COM FAILURE". Turned off the ignition tried again and it started. Stopped couple of times on the way home and no problems. Today tried to start it and got same message. After 3-4 tries it started. Turned it off and started it 4 mores times with no problems. We spent 10 days in Port Aransis and I'm concerned that I could have a salt corrosion issue. Chassis battery is at 12.6V. We also drove in some heavy rain. Did a Google search and found some references to a connector by the transmission that might need to be cleaned. We have a Tiffin 2014 Allegro RED 33AA with the 2500 Allison transmission. Any suggestions where to look for this connector or other thoughts to what might be the problem?
