ETA for our departure is 8:00 AM tomorrow morning.
I had the truck at the mechanic's today. The shift-interlock solenoid intermittently does not disengage.
The mechanic installed the new part and it exhibited the same issues so it is probably a harness issue, either a wire that is broken or a splice that is touch-and-go.
I made the executive decision to leave the interlock plugged in but mechanically disengaged. There is enough room in the steering column to disengage the popsicle stick from the shifter mechanism and chicken band it out of the way. The computer thinks it is still there but the mechanical linkage doesn't know it is there.
Fortunately for me, Mr Shadetree was willing to do that.
There is some last minute running around to do, including calling Ducky to see if it still a GO from their end.
