Obviously, it requires knowledge, practice, and skill, but when properly executed, is clutch-less shifting good, bad, or otherwise?
^ could NOT have explained that any better!The synchros are not meant to work with power being transferred through them, so you will be running the risk of drastically shortening their life. This really should only be done on a non synchronized trans or crash box designed to be shifted in that manner. You won't hear a grind unless you are way off, because the synchro will still be matching gear speeds. It's a common misconception that no grinding means you did ok. You'll never know you are off unless you are driving a non synchro trans, and in that case you will hear and feel it immediately.
When I drive a non synchro trans, I only use the clutch for starting and stopping. All other gears are shifted by floating it in and out at the correct ranges in between driveline load shifting from accel to coast.
Your typical passenger car trans is not set up to endure this. Synchros are wear items, and will wear out prematurely if they are forced to work against engine torque.
No no, what Im describing is shifting a regular manual transmission without using the clutch via rev matching.
You must really respect your employer. I guess unforeseen repair costs don't trickle down to salaries, raises, bonuses, layoffs, etc. where you work like they do in other organizations. I'm sure it's fine...everyone does it right? Reminds me why I never buy a used car from a dealer. There's always some guy like you out there.You are forgetting one important question. Is it your car, or someone else's? I rarely use the clutch on the site trucks - Toyota Land Cruiser 70 series (google them). It is fun driving without a clutch, especially if they are beat on work trucks, you don't have to pay for the repairs, and you can always blame a driver for blowing the transmission. Also, I figure it is a good thing to know how to do in case you ever have to do it.
My own car? Use the clutch. Unless it is an 11 year old Nissan Altima getting traded in later that week.
