Didn't know car was high centered. Put it in park while power was still to wheel

What is your question?

I was trying to rock it out without knowing that the vehicle was high centered. So believing I had all wheels on the ground, I put it in park The right front wheel was turning at idle speed because it wasn't touching the ground and I wasn't moving so I didn't need the brakes. I heard a loud clicking sound and after I got it out, I had issues. The engine runs fine when parked, but the tach goes up to 3,000 to shift out of 1st and will go much higher than that if I put my foot into it. And there's a rhythmic whine that is quite noticeable. So did I strip some splines on the transaxle, fry the CV, or what? Surely I didn't damage the transmission itself.
