AW4 Shifts Early, Sticks in OD

My AW4 started shifting early today. Here are the symptoms.

-Shifts quickly into 3rd gear by 30mph
-Wont downshift (passing gear) for whatever gear Im in. (Say, if im in 2nd and floor it, it will stay in 2nd and slowly accelerate)
-OD still hits at 45mph, but wont disengage unless I either hit the brake, or coast below 30.

I got MINIMAL water on the outer case of the TPS today while cleaning the engine bay...I was careful, but may have gotten more water on it than I thought.

I thought when you get water on the TPS it doesnt shift out of first.

Can my symptoms still be the TPS? This one is 2 years old.
 
You know the TPS got wet;... that would be a goood place to start the diagnostics. There is no book of rules when it come to failure of the TPS. It fails in whatever way it wants. When mine got wet I had my a$$ full getting the engine to run. When it did run it wanted to stay at idle or above 2,000 RPM, nothing in between. Others had problem with the AW4.
