Based on this new info, I'm gonna guess misalignment of the clutch driven 
plate on the tranny input shaft, possibly combined with lack of complete 
throwout bearing release. If the shop couldn't figure out how to open the 
hood, what're the odds they know how to use a clutch alignment tool? 
Normally I'd expect it to go away with the clutch depressed, but if the 
clutch forks aren't set right the t/o bearing won't completely release the 
clutch allowing the driven plate to spin. Does the truck want to creep in 
gear with the cluch out?
