100% agree. Scott your 997 gear box must be malfunctioning. My PDK is phenomenal still. Normal = Lexus (don't use it). Sport and Sport Plus are very responsive.

I had a 911 manual gearbox And remember Porsche dealer saying to me that when i tried the PDK I would want one....he was right. After 2009, 90% 911 sales were PDK. Nothing compared to sales tiptronic vs manual before 2009.
Its a really amazing gearbox.

I looove my 2012 997 GTS. I will admit, however, that it is taking a little time to become accustomed to the PDK having been a manual transmission Porsche driver until 2 mos ago. The downshifts when using the paddles are a little off in that they are rough if not careful..and delayed requiring more braking than I'm used to if the transmission is set to shift itself. The shift up from first to second with the paddles in M takes a little too long. When I allow the transmission to shift itself I find that I'm always in a higher gear (perhaps for fuel efficiency settings) that I want to be under the driving conditions at the time. It certainly is a smart and efficient transmission. It takes some of the work (and fun) out of driving. She hunkers down and gets the work done when needed. But I feel it needs a few tweaks. I've heard, word of mouth, that software adjustments may be available to adress some of these issues. Staying tuned.

It took me a while to find this post but I felt it necessary to update the community with my experience. I earlier stated how rough my 997.2S PDK was shifting in comparison to my 991S.
As Adias suggested I took the car to Champion and told them about what I was experiencing as far as how the shifting felt. I got the car back and it feel EXCELLENT. The shifts are significantly smoother and faster. The PDK system was updated and recalibrated. I also had a recall on the fuel pump which was taken care of.

If it wasn't for this thread I wouldn't of known. Thanks.

The 991 still shifts faster though ;-)

Just tested a new 991s w/ PDK and in comparison to my '10 997.2 PDK it was almost identical in "normal" automatic mode. In advanced automatic modes again, almost identical - meaning I really could not tell the difference. In manual modes I found a slight difference in favor of 991, but it may have been really paddles (991) versus buttons (mine) as I found the paddles were faster to execute my desired shift. My 991 opinionated conclusion (only the PDK portion) is both work about equally well when properly calibrated.

I couldn't agree more. I also love my 2012 4GTS and I'm working on becoming accustomed to the PDK after 3.5 years of my manual. That said, it's getting better every day. I felt sort of lost the first few weeks going between the paddles and automatic but now I pretty much leave the car in manual and shift with the shifter, as opposed to the paddles. I find that it feels very close to the manual in terms of familiarity of where my hands go, but with increased responsiveness (and obviously, not having to use my left foot). I'm getting to the point where it's the perfect balance of what made the manual so much fun but also benefitting from the PDK technology and faster shifts...so I'm a big fan!

After a lot of years driving 3-pedal Porsches, I bought a GTS with PDK 16 months ago.
I found the adjustment (from manual to PDK) to be pretty easy, and I got used to the new set-up quickly.
Even though I have the paddle shifters, I, too, find myself manually shifting mostly with the gear-shift lever.
Now, if all manufacturers (or even all German car makers) would just settle on one way to operate these "manumatic" gear boxes. My DD MINI Cooper S operates exactly the opposite (pull to upshift, push to downshift) of the GTS .
Makes me have to think too much.

i agree that the new PDK is smoother and program much more aggressive in non sport mode. That symposer does make a difference in how it "feels"

The weight difference between a PDK and MT car used to be 66 lbs. It's now 45 lbs. Maybe the new 7 speed is heavier than the old 6 speed but, performance differences aside, I think the new PDK is also lighter than the old.

coming from a 997.2 PDK owner to a current 991 PDK owner, the changes are vast... its surely software related but i think/feel the ratio's are changed as well...

the shifts are faster, more abrupt, the downshifts have more gas blip, the vehicle no longer has that "torque converter" feel, as if the clutch is "being feathered".. it's more all on or all off like a manual trans..

car/trans feels great, yes the ferrari system is still better but the pdk is def a very close #2 in the world of double clutch transmissions..

if i can find the articles, i will link em.. but from personal experience the 991 pdk is def more raw and "automated manual" than before where it felt like a fast shifting tiptronic.

rijowysock

as with race cars, should be the opposite of porsche... dont know why they do what they do..push to down shift is the standard.

rijowysock

put it in kickdown mode, or get on it, easy to tell difference.. driving 997.2 pdk for 18 months, and 2100 miles in 9 days on 991 pdk... it's easy to tell...

Did you have sports chrono in your 997? If the answer is no, then that explains this post. The differences are not vast.

I know you trade often so I may have missed one but didn't you have a 997.2 PDK without SC? Is that the one you're using as a reference?
