Clutches are good!!
But, in a "big-rig", a car, or anything else that manual transmition, it's possible to shift without the use of the clutch. I did this a couple of times on my '86 Interceptor and I was curious (ex post facto) if it's bad for the tranny in any way.
So...is it bad to clutchless shift?
There were no clunks, grinds, or other illtempered sounds. Just a nice smooth shift.
