2007 Honda Rancher ESP 4X4
 

I recently purchased a 2007 Honda Rancher ESP 4X4 and when in automatic it is slow to move like the brake is sticking or it is stuck in a higher gear so to speak. If I come to a stop and start again, or use my thumb to give it gas a few times, it usually moves right along. In manual it seems to work great. any idea on whats causing this problem so I can repair it. Definitely want the automatic working for when the kids drive it. thanks.
