Troubleshooting no forward or backwards motion?

2003 Jaguar X Type 3.0 Automatic AWD; I put the car in reverse, neutral, and drive and can feel it engage and see it on rpm gauge but movement. I put it back in Park and get a noise for a short bit that sounds like it is rolling as it goes into Park and noise stops. I can still push car forward and backwards even though it's in Park ? Help Thank You . . .
