it doesnt mess up anything cause there's no load or moving parts whatsoever

 

I did it one time and the high engine speed blew my my 6th gear out. The car doesn't do 155mph the same anymore.

 

Just restating what an ase certified master tech told me when I was sitting in the show floor s2k @ my dealership shifting around. I'm sure one time one mess things up.

 

Road rage or xviper, any technical insight on this?

 

how does it mess up the synchros?
the synchros help move into gear while there is load...there's no load so the synchros are not wearing at all
and it isnt hard becoming ASE certified.. its like getting a bartender certificate... doesnt mean anything...

 

It won't hurt anything. Read this.

What about when the clutch is not depressed??

 

You don't need the clutch depressed to shift through the gears with the car off since there is no load.

 

my opinion on the clutch is if u feel resistance when trying to go into gear press the clutch and it eases in
dont force it

 

Here's an idea. Don't do it and don't let anyone else do it.
