I am currently driving to Colorado then Arkansas from Alaska. We finally made it into Utah and as I pulled into the hotel parking lot I hear some sort of clanking under my feet and in the stick. I am pulling my camper and have had no problems. Also at speed I don't hear or feel anything. It is only when I am going very slow, a couple mphs or stopping. Mainly in first or second gear. I am hoping this is only the clutch. my other concer though is I had the transmission fluid changed before I left. I looked under the truck tonight nad there is fluid splatter from the front to back all over the place. I am wondering if it is the new fluid found a bad seal or what. I am going to Grand Junction, CO tomorrow for a few days. This is all worrying me and I am losing sleep. Any help or ideas would be great. Thanks.
