Welcome to the forums. Yes, it has an auto-clutch. There's no lever to pull in. As you move the foot shifter to change gears, the foot shifter is attached to linkage on the inside of the transmission that disengages the clutch automatically. Just shift as you normally would on any manual clutch quad or bike, except you don't have to worry about pulling a clutch lever. Just accelerate until you need to shift into the next gear and then let off the throttle and shift into the next gear and then hit the throttle again.
As Shadetree was saying, that model has ten gears............5 low gears and 5 high gears, plus reverse. Down on the left side of the quad, you will see a shifter with a plastic knob. This is how you shift from low range to high range to reverse. Before using this shifter, make sure the ATV is stopped and in neutral. To shift into low range, pull up on the plastic knob and move the shifter all the way forward. To shift into high range, put the shifter in the straight up position. To shift into reverse, put the shifter in the rearward position. Then, push down on the shifter to engage reverse. You may have to rock the ATV a little to get the shifter to engage. Never try to move this shifter while the ATV is moving in gear. Once you have the transmission in the range you want, you will then shift with the foot shifter. All the way up is neutral. To upshift, push down on the shifter. To downshift, pull up on the shifter. This model shifts backwards as compared to most models.
Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!
You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.
