I started doing it every downshift to get used to the motion again, and it's automatic for me now. I downshift just as smooth(if not smoother) than shifting up... Also, I can downshift into 1st now_-Night-Shade-_ wrote:Lol no man, here's how you do it: let's say you're in 4th doing 60km/h (about 2.5k) and you want to downshift to 3rd, which would be around 3k or slightly above. If you just clutch in and downshift and clutch out, when the clutch engages the car will jerk because the engine will be sped up to match the speed of the tranny. Rev-matching (giving it some gas with the clutch in to get the RPMs up to what they would be in the lower gear) will get rid of the jerk when the clutch engages but the synchros will still be doing their work. So to properly double clutch here's what you do:
Clutch in --> shift from 4th to neutral --> clutch out --> rev up to what the RPMs would be in 3rd --> clutch in --> shift from neutral into third (should go in like butter if you did it right) --> clutch out --> you're done.
This is all done very quickly and should take half a second, you can YouTube it - there are some nice videos of pro drivers doing it while racing and you can see how quickly they do it.
Do our trannys not have syncros on 1st? or did I just get 2 crappy trannys in a row? :/
Either way, I can do it now.
