I haven't got a clue about driving a manual but hey, I can google stuff. From http://www.standardshift.com/faq.htmlQuote »Double-ClutchingTruck transmissions don't have synchromesh gears which allow you to shift even if the input and output shafts are rotating at a different speed. For a truck, you need to match speed with what the engine and wheels are doing. Shifting for truckers is a two-step process. Hit the clutch and put the transmission in neutral. You then quickly tap the accelerator to match engine revs with what the wheels are doing, hit the clutch and put it in gear. You can use this method to see how smoothly you are shifting normally, and helps you learn how to rev match. The benefits of rev matching include smoother transitions between gears, especially on downshifts as well as reducing the wear and tear on the synchromesh gears themselves. Hopefully that is correct information. Sounds as if it applies to the big rigs but may be useful otherwise...

thank you for your input

That's what the synchros do for you. Takes longer than what you're doing now. To rev match on a downshift, just tap the gas when your moving the shifter to a lower gear while the clutch is depressed.

I ussualy only do it when I'm on driving around town and crusing... not on a highway merging Double clutching in a semi is why they seem to take forever to go through the gears... but they also get a lot more miles out of their transmissions than any of us would dream of.

double clutching is what you do instead of granny shifting, any real racer knows that.

[tangerine]

lol, platnum been watchin Fast and The Furious. Vin Desil told him he spent too much time granny shiftin and not double clutchin like he should have been. 'You never had me, and you never had you car!'

Double clutching is actually slower than 'granny shifting' too... and your car is only 170 hp not 180

i actually double clutch often. it help when your tryng to go into second above 45 mph and stuff like that.instead of shocking the synchros and lurching.but yeah. clutch-neutral-rev-clutch-gear.

[Emerica13]

You can usually simply pull the shifter out of gear if the rpms arent too high, then just blip the gas and push on the shifter and let it drop into gear, takes a while to do right, and imo, not worth the risk of damage/embarassment of grinding gears

grip it and rip it!!

And you can really only do it in higher gears, you still need to feather the clutch when starting, or just dump it at 5k... whichever - you still need the clutch. Timing the shifting is the trick... I wouldn't recommend doing it on every shift - it can't be good for the tranny!

For the past year I have only been floating my gear's trying to avoid wearing out my clutch.My clutch has only been used to start with or when racing.The Vibe is very easy to float because of there tapered gears.There is nothing wrong with floating gears, as long as your not grinding them. It'll save wear and tear on your clutch disk and throw out bearing as well as the wear on your transmission syncro's.

Normally on down shifts I ride out the current gear and when slow enough step in the clutch and go to neutral. When I do want to downshift I rev match. Step in the clutch, a little gas, choose the lower gear and release the clutch. Rev matches are better for the trans since you do not shock it by just throwing it down into the lower gear, better for the drive shaft too if RWD. You do not "jerk" the car by down shifting and rev matching, a smooth transition is what happens instead.

Aren't the synchros what take the impact of an un-revmatched downshift?

[ToolGuy]

Not sure, this is the first manual I have actually ever owned. Maybe some one else can comment?I mostly rev match to smooth the transition into the lower gear, the engine likes it!
