In any case,

For all who need clarity with shifting....
Check out this site, very useful and accompanied with pics you can get an idea for what is called "heel toe downshift" not the same as "double clutching"
Although its referred to as a racing technique I'm sure the more experienced drivers out there will see just how important it can be to relieve undue stress on the manual tranny.

Normal shifting in car with synchros --> clutch-in, move shifter down to next gear or deired lower gear, ease the clutch out.
Double clutching, can be done in a car with or without synchros --> Clutch in, move shifter to neutral, clutch-out, match revs to desired level based on lower gear your going to go into, clutch-in, move to desired lower gear, clutch out. (2 clutch ins, hence the doble clutch)
While doing this in cars with synchros isn't necessary, as has been stated, it can also be used when wanting to downshift while in bad driving conditions (slippery roads). By double clutching it makes the transition smooth, as opposed to being relativly jerky by letting the synchros handle the rev match.

As stated, rev-matching is a good thing, double-clutching is not necessary (if it's fun for someone, go right ahead
)

G35NOW!: I wouldn't say double clutching is necessary in transmissions nowadays, however with my car, when the transmission is cold, it is. Quality transmissions don't require it at any time, however this transmission is the G's, if not Infiniti's achilles heal (sp?). Keep it in a truck where it should be and give me something that belongs in this car.
With said, have a good day everybody!

- Push in clutch and begin moving gear lever
- Tap the gas pedal (push it down a bit to rev the engine - with practice you'll know how much - then let off quickly)
- Finish gear change, let out clutch smoothly before engine revs come back down. If you do it right, you'll be in the right rev range for the new gear at the same speed. This way drag on the rear wheels is smoothly changed vs. abruptly
And this from an AT guy!
