Proper way to shift 6 speed?
I've had my 01 TT for a month now, and after 10 years of not having driven a manual, It has become second nature again.
I have noticed that if you shift the "wrong way" from first to second, there is a noticable "POP" (muted clunk) as the transmission/driveline is still somewhat loaded, but unloaded enough to release the gears. The POP occurs when I accelerate in first then, in one motion at the same time, pull the shifter out of first and depress the clutch. Since the clutch is "on the way down" (but not fully disengaged yet) as I am now pulling on shifter to go into second, I think the trans "lets" go of first when still partially loaded as soon as the clutch STARTS to disengage, this lets the gears POP as they are forced to release before fully unloaded. It is very easy to avoid this POP by making sure that I "feel" the floor with the clutch pedal before pulling on the shifter, then a perfect shift results. Basically a two step process - feel the floor, pull lever. I suppose if I timed it just right, I could have the clutch pedal all of the way down at the same time as I pull the lever, but this would require that I start to shift AS the pedal is on its way down, hoping to have full disengagment coincide with pulling lever. So far, if I don't think "two-step" and try to do all in one motion, the POP results about 25-50% of the time because of my poor timing. I am sensitive to "feeling" the trans as I shift, so I do not force it out of gear, its basically allowing the disengagement with a little extra pressure on the lever (in keeping with the additional force one uses when shifting more quickly than usual)
I do seem to remember older (86) 911's having the same POP under the same conditions - yet I don't remember any other (brand) vehicle that would POP (they just hold onto first until more fully unloaded, even when I push/pull in one motion) - is this unique to the Porsche trans (probably some design similarities [quirks] still exist between 86 911 trans and 01 996 TT??)
I would be very interested in hearing from the group on the POP issue, and if you just push clutch/pull lever at same time or ? , especially from the members that can shift quickly enough for the 10.74, 11.3, etc 1/4 times - I really admire your shift techniques, its truly an art to shift that well!

I have a 01 turbo and primarily run DE events. It sounds like you are pulling the shifter out of first without completely depressing the clutch. Porsche's have never had gear boxes to power shift. They best respond with deliberate shifting. I have found that the 1st to 2nd shift a little tricky and works best if you run it up to about 4000 RPM before shifting to 2nd. Additionally a good practice would be double clutching.

Yeah, I have expirenced this POP if I dont push the cluch all the way, but I am usually not in a big hurry while shifting, so I just make sure that the cluch is fully depressed and then I shift. Every once in a while, I try to shift, an the gearbox wont let me shift, it just stops the shift lever from going from 3 to 2, just like it stops you from shifting from 6 to reverse... weird?
