2006 Rancher 400AT–ESP not working and high RPM’s in manual

Originally transmission would not shift in ESP or Manual. I performed all of the electrical test and found that the angle sensor was bad. Changed angle sensor and code and problem shifting went away. Went for a ride and used to pull a pull behind bushhog to perform some mowing. Now it will not shift in ESP and when in manual, RPM’s are high and bike not pulling like it should. Is the clutch toast?
