The symptoms you will experience if the (starter clutch, 1st, 3rd, 5th, & R gears) is slipping in AT mode or even manual for that matter.
On take off may or may not spike in RPM upon initial take off, then shift into 2nd normally, them spike in RPM shifting into 3rd, shift into 4th normally, spike in RPM shifting into 5th, then shift into 6th normally.
If you didn't really damage anything the symptoms may not be repeatable when the machine is cool or normal operating temps.
The above will primarily happen once the machine is hot, as in several hours of slow trail riding where the clutch engages and disengages crawling along at 3mph or less, compounded by inclines.
If you really get it hot and the clutch plates get glazed the machine will make a shuddering feel, and noise on take off. Once all material is gone off that bad clutch it really gets pronounced.
This video shows it doing so somewhat, I had one I shot showing severe shuddering but cannot locate it on YouTube.
