Automatic tranny, reverse died during cold snap

Question

The vehicle is a 2005 Chevy Classic 2.2L four cylinder. It starts and runs, or ran and drove, fine down to -15-20° F up until recently. With a few days of -30 and -40 temps, the car, even after 30-45 minute warm ups, tended to shift balkily at times, for a couple of days skipping 2nd and shifting only after the car was moving close to 40 mph. So I drove it quite carefully. Then suddenly, after running and driving for over an hour on a sub -40 day, I lost reverse. I thought it might come back when it warmed up, but now, even at 0° F, there is no reverse. The engine will rev in either Park or Neutral, but the engine has a load when in reverse. The car just doesn't move. Thoughts?

i can't commenting for gut answer,
but here is my guts answering:

your disc is break / damaged.
your solenoid jammed

solution for 1:
try to drain your transmission fluid, if dropping some dirt like brittle and like small hard piece than it might be true, your reverse disc broken, it maybe you need to change whole disc since some dealer only selling a whole pack and avoiding future break.

solution for 2:
check voltage across your trans shift, it should have voltage going to reverse solenoid. dit could be just the shift knob is broken (cheaper)

if the voltage is good, than you should check the solenoid in your transmission, check whole solenoid try to jumper with 12V directly (this should be only be done by professional mechanic) if it still works than it could be your worst nightmare on whole transmission.
