I had someone driving my truck while I was loading some hay. Thought I could hear the engine lugging while it was stopped. Then I could smell it. The clutch was being cooked. By the time I had noticed it, I am sure it got very hot. After changing drivers, I could smell it for the next hour. It was not a few days later when I noticed it slipping with the TST on level 5. It does not slip on 0, but I can not turn the TST on at all. I am working on getting a new clutch within the next few weeks.
By only moving it 5 feet, I bet no harm was done to your truck. Problably harder on your brakes than anything. Time will tell. I few bombs here and there and you will be upgrading it. Mine has made it 44K miles.
good luck.
