My truck has only 26000 miles on it and last week I noticed the clutch starting to slip,I am the only driver of the truck and always start off in 1st gear and at a stop I always put it in neutral with my foot off of the clutch, I baby this thing,and have been driving standards all my life and have never had to put a clutch in any truck that I have ever owned . Is this normal for such a heavy duty truck. Will DC warranty this?
