99 4runner Limited...

The other day we had a large amount of wet and heavy snow/slush fall in a short period of time. I had about a 20 mile drive home in the stuff, so I threw it into 4high. I didn't have any problems getting home, however when I arrived, I couldn't shift gears past neutral!

By putting pressure on the handle, I was able to engage reverse, though the stick didn't actually lock into that posiiton. I took it out of 4high, when forward and reverse a few times... No luck. I left it in neutral overnight with the parking break on.

The next day, I could shift smoothly into all gears but PARK. By the second day, no problems at all, PRD2L all good to go like the day I bought it.

Any ideas?

You know how you have to break to shift into park? I'm wondering if that sensor temporarily crapped out somehow due to the weather conditions.
