Atticu5, there's a difference between overevving the motor while accelerating, and overevving due to a missed shift (in a stick car) mainly because if you floor it (for example) in first gear, you'll just bounce off of the rev limiter...shouldn't hurt/kil the car. However, if you mis-downshift into 2nd when you go for 4th, it wouldn't matter what your rev limiter is at until you either put the car in neutral or engage the clutch....a situation like that is like you described, and will most likely cause damage if you shift into a much lower gear at a higher speed than you intended to :)

I thought the transmission would just prevent you from shifting if that gear would be over the redline? I know in my friend's car you can't put it in 1st unless the car is almost stopped.

that just means his first gear doesn't have a synchro.. you can put a car into any gear regardless of speed(except reverse) assuming it can handle it mechanically

Well, it's a distributor that has electronically controlled timing advance. It's not terribly old. :p

Though this does remind me that I need to clean and gap the points on my other car. ;) :D

Actually, my car has full synchromesh and it's still possible to "lock out" a gear if you try an aggressive downshift. A 4-2 downshift often requires double clutching.
