Downshifting Problems

[OldJimmySutton]

Hey there fellow 4Runner pilots! I was cruising around in the higher elevations yesterday and got into a bit of a sticky situation. Long story short I was faced with a long, winding, and snowy decent. My nerves kicked in and I dropped her down in 4wheel low and low gear and began my slow creep to the less frozen lands below. Everything felt fine and I reached the paved and dry portion of the journey successfully. I popped her back up into her native 4 wheel high and proceeded. Upon intiating my usually downshifting hill decent protocol I found she wouldn't downshift from drive at all! No difference between any of the lower gears and no sound of the lower gears engaging. My brakes are very warm and I am very sad. Any idea what might be going on? Thanks a bunch!

I pilot a 2003 limited
All wheel drive. All the time.

If it still drives normally, it must still be able to shift and it's just not getting the signal to downshift.

What happens if you put it in L and try to accelerate from a stop up to 30ish mph? Does it act like it's in L or D?
