Ok I have a 2007 rancher AT over all I like the automatic so far. I have not had it long,but it shifts good in automatic and up and down,but the other day I started up a hill and something started slipping and had a hard time making it up the hill. I checked the front and rear differential because looked to have a little water. But I'm trying to figure out what is slipping and a good process of elimination. Any suggestions?
