3 days ago the transmission kicked me out of gear then ultimately stuck in 2nd gear. Had some splines replaced at a tranny shop ($800) then back on the road yesterday. This morning when trying to start it, nothing. Checked the battery, starter, selenoid, fuses and think it might be a grounding issue. After holding the odometer and trip buttons to check for error codes, I got...

Code 940 -no CCD bus messages from powertrain control module

Not sure what to do next. I'm stuck in McCall, Idaho. Should I replace the relays, pcm?
Open for suggestions. Please help!
