I've got a lot of the bugs ironed out but this one is still throwing me. At random times while out driving the transmission will decide to downshift to low 1. Doesn't seem to matter if at the time I'm then in 3rd or in OD, or what speed I'm going at the time, but it will abruptly downshift. Depending on what I do at this point I get one of two results...

Once I'm down to 20 mph or so I can accelerate again to 40 mph or so, but the transmission won't come out of
1st, won't upshift.

Or, if I pull over, stop, and put the car into park for a moment or three before dropping it back into drive, it will accelerate and shift normally, and may not do another unscheduled downshift for the rest of the drive.

Sound familiar to anyone? Thanks in advance for any thoughts and suggestions on it.
