997.2 6-Speed Transmission - Notchy?
#61
Well, I thought I would give an update to this thread since I started it about 2 years ago. I still have my 2009 997.2 C4S and yes it is still "notchy" shifting between 1st and 2nd, whether it is hot or cold (doesn't get very cold here in AZ). If I "short shift" between 1st and 2nd (less than about 3000 RPM) and do a very slow shift, then it tends to minimize this notchy feeling. A hell of a way to have to drive a Porsche, but I guess you have to do what you must to solve the problem. As someone once said, 1st gear should be used only to get you moving away from a stop and then "go for it" in the rest of the gears (although that doesn't help you when you are trying to get that "hole shot" away from the stoplight when you are next to a Corvette or Ferrari!!).
BTW, I just drove my first 991 with the 7-speed MT at the local Porsche dealer. A very "sweet" gearbox - head and shoulders better than the gearbox in my 997.2. Oh well...................

He "injected a bubble" in someone's car... I can't think of any good thing to do to the car that would be described that way. My grandfather did break an egg into the radiator when my Mercury coupe had a leak, but that was in 1959. This sounds like a similar home remedy and probably also works. For awhile. But I'm a little surprised to hear a Porsche dealer admit to trying it, whatever 'it' may be in this case.
Assuming you've read the rest of what we said about this already, I strongly suggest you try the other Cincinatti dealer and begin by asking for a test drive in another 997.2 so you can personally judge whether "they all do it". Clearly, it is not our experience that they all do it. Quite the contrary.
Again, you need first to read what we more experienced sports car drivers have said about how these transmissions feel when you try to drive them like a sedan, but assuming those explanations don't clear things up, two possibilities come to mind, and they both require dealer attention:
Again, don't make a big deal out of it when you make the appointment, but I'd definitely try the other dealer because your current one has committed to the non-diagnosis of "they all do it." I would not even mention the other dealer. Just make an appointment. Driving one or two other 997.2's is also good. It will give you the personal experience to refute that assertion if you run into it again.

- The selector shafts and/or the shift actuator cables need adjusting;
- The clutch is nearly worn out and needs replacing.

Thank you for the response. I have had the car for a year and it only has 8000 miles. I certainly do not expect a "sedan" type transmission as I have driven sports cars for years. Once the car is warm, I still struggle to get it in gear. I will never force a stick into gear and on occasion I have to wait a second or two for the gears to stop so it will fall into place. I can feel the gears moving as I wait. This happens on 1,2,3 and 4. 5 and 6 are not as bad as I do not have to wait.
My first comment to the dealer was that there is something that needs adjusting. I guess that didn't sound right to them. I will try what you advised in your post.
Also, I have read a great deal of your posts. Thank you for spending the time writing them as they are very informative.

Some quick arithmetic also tells us that the original owner only put a couple of thousand a year on the car. That's not unusual with Porsches since they are often bought as the fun car while a couple of sedans do the majority of the family miles. It means first that it isn't very likely to be the clutch. You would know the other symptoms of a prematurely destroyed clutch and routine wear won't begin to show that early. That leaves adjustment issues at some stage in the driveline. I can easily see someone who isn't a perennial Porsche owner just tolerating the awkward shifting for as few miles as that original owner put on the car, which means we probably have a condition that began at the factory. Just a slight over-adjustment here or there can make a world of difference in transmissions that transfer as much torque as ours do.
I still would find a way to drive a couple of other 997.2's. Not to rule out this being your imagination, because your experience does that, but to better inform your sensations when you compare the examples with your own. That way you can be very specific about the differences when you talk to the new mechanic about this.
Once you get someone who isn't already committed to non-action, I think they'll solve it quickly. If they are stubborn, then get PCNA involved. The car is still under warranty unless my arithmetic wrong, so they need to fix this -- and they can if you get the right people to examine the car.

Get this issue logged and recorded by your Porsche dealer so you have some documented proof you had a problem . That might help you later on should a real issue turn up... gearboxes and shop rates are pretty expensive. I agree with Gary that our cars are sports cars and therefore are more " temperamental". Try a Ferrari or a Maserati with an F1 box. However, my 996 C2 was very smooth (but long) , then after installing a SShifter it became more accurate and knotchy which I loved. The car never stumbled because of gear selection issues. My current 996T is as smooth as butter too but I change gears only " as fast as I think the box will / can take it and I take great care to "guide" the gear shifter in 1st, 2nd and 3rd to make sure I do not end up with the gear pop-out. I would say my box feels top notch, so good inf act that I have no intentions of installing a Short Shifter.

I realize this is an older thread but I thought I would jump in as I have the same issue. I have a 997.2 4S (2009). I have become frustrated by my shifting problems and the response from my Porsche dealer. This post is not about my car when it is cold as I do not believe this is a good time to evaluate an issue. I actually think it is good that it needs to be warmed up before it performs. "Clunky" is a good word for the feeling. I came to this site to learn what to say to the dealer when I take it in for the 4th time with this problem when I found this thread. I knew I found the post I was looking for as soon as I read the subject line. Here is what it feels like to me in addition to "clunky". It feels as if the clutch is not pressed in all the way when I switch gears yet I have it to the floor. I asked the dealer about this on my first visit and he admitted that it was close. He said he has injected a bubble in someones car and that worked but the bubble will go away and I will be back. The next visit I was told they didn't experience a problem. The third time they said they looked at it and told me my transmission was very strong. What??? The strange this is that the dealer described my issue perfectly when I dropped it off as if he knew what was going on. He suggested I have a brake flush as the clutch fluid is related to the brake fluid.
The gear switch problem is a real burden. I do not get excited about driving the car as I know that I will really have to work when driving the car. I spend more time making sure I have the clutch all the way to the floor and that I am smooth as silk to prevent any damage to the car. If you do not understand what I am talking about, you don't have the same problem.
Does anyone have any suggestions for my next visit to the dealer. I was thinking that if they say it is normal, I would ask if they had any cars with the problem on their lot for sale. If so, I would like to drive it. If they don't, it is not normal.

My issue has been resolved! I took my 911 4S in for an oil change and brake flush yesterday. I mentioned the clutch again and asked for a tech to go for a drive when they finished. I also mentioned that my tail was not going up by itself as I had someone follow me doing 85. I decided to take my computer with me and wait since they stated it should take less then 2 hours. 4.5 hours later I was told it was finished. They said the clutch was fine and so was the tail. They gave me a tech and he took me for a drive. The first thing I noticed was how smooth and effortless the tech was switching gears. It made me wonder if I was driving the car wrong. The tech was a wealth of information and nice guy. When we returned he stated that the clutch felt great and that next time it felt funny to just come in. I got behind the wheel to leave and instantly noticed a difference when I engaged the clutch. All of my shifts were smooth and the clutch was amazing! I drove it for an hour and found I had a grin from ear to ear. The grin was not because the problem was resolved but rather the exhilaration of driving the car as it was designed for the first time. I also noticed a change in the tail. It went up for the first time. I walked by my garage 5 minutes after I arrived home and found a fan running. I actually walked into the garage and directly to the back of my car only to figure out it was a cooling fan on my car. This is the first time the fan has ever worked to my knowledge. I'm not sure if the brake flush fixed the problem or if they did some additional work. I'm not sure if they did something with the tail or if it just started working. The only thing I'm sure of is the problem(s) have been resolved.

My understanding is that the brake and clutch share the same fluids and hydrolic lines. I am sure someone will correct me if i am mistaken.
It seems that your issue may have been due to the hydrolics or possibly air in the line. Im no techy but that seems logical to me.
I also felt my 2010 997.2 C2 was a little stiff and notchy until I changed the shifter to OEM SSK. It felt better immediately and now recently had the brake flush at 10k miles. I am not denying that it may be psychological but i definitely notice an improvement in the smoothness changing the low gears.
Regardless, congrats on the "grin"

I drive a 2010 Carrera 2 with 55tmiles and 1. clutch.
Regularly, from a full stop, when I try to put the car in first gear the transmission blocks completely. So I have to double clutch and try again. The car behind me starts to honk which gets annoying....
Also have a notchy shift from 1. to 2. gear and can not really shift directly.
I suspect that synchronizers are worn but not entirely sure.

Cool Flash,
I took mine to the Porsche dealer a couple years ago after I just got tired of the "notchy" 1-2 shift and had them look at it. They of course said that they could find nothing wrong. Now I just live with it - I think this is just inherent to the 997.2 manual gearbox. BTW, my girlfriend has a 2009 Boxster S and its 6-speed is "smooth as butter". Oh well.....................

I just got a new-to-me 2011 C4 and am driving a manual transmission for the first time in a while -- my last car with a stick was a 2000 Audi A4. I notice a little resistance from my transmission, when the car is cold (which has been the norm lately here in Boston), but then it clears up once I've been driving for a few minutes. I have noticed that I have to be precise when shifting back into 1st gear, but that I'm able to select 1st without much of a problem. Other posters have the comment about Porsche having world-class manual transmission and i couldn't agree more. Love the way my transmission and clutch feel -- very natural and smooth. My only beef is that 6th gear isn't tall enough for me. Perhaps this is where the 2012's 7-speed has an advantage. That said, with my mix of small-town traffic and highway congestion, I'm amazed that I'm getting over 22 MPH in my C4.

That said, with my mix of small-town traffic and highway congestion, I'm amazed that I'm getting over 22 MPH in my C4.
Also, I felt the same way about the gearing of 6th until I drove it a while and got used to where the car likes to RPM wise. I'm not sure how well it would feel at 75 mph lugging around at 2k RPM's?? They like to rev and I find myself in 5th a lot at 70-80 mph especially if there is traffic and I'm on and off the gas, getting a little engine braking. 6th gear feels like it's just getting started at 110. Anyway, if anything I would 1st gear to be a few teeth longer. As I do tend to "use 1st to get it rolling, then let it rip in the other gears". If my brain is not thinking "SHIFT" at 7000, then it's easy to hit the rev limiter in 1st. Unlike other cars I've driven, this thing makes power all the way to redline...and beyond if you note the GT3's and such. Feel like it could go to 8500 no problem!
My bigger issue with my car is that stumble/hesitation it tends to get when you short shift 1st to 2nd and land in the 2600-2800 rpm range, nearly impossible to get a an easy smooth shift, it takes some work...OR just run it up to 5k and shift it harder. Doesn't always do it, but it's an issue has been discussed in other threads...sounds like a variocam issue.
Bottom line...it's just not a pedestrian, general public transmission and clutch. I've driven manuals my whole life but this took a little more time to learn to be smooth for sure! And the jumpiness and difficulty is even worse (for a new driver) in Sport Mode! The car actually drives better IMO in Sport mode, but it took a while to not buck the car if my foot got bounced or I wasn't smooth! I hopped in and drove numerous 997.1 cars on test drives and it felt like as easy as a Civic! This 09 is a different animal, especially in Sport mode. Imagine a guy like me, that "can drive anything", goes in for a test drive and bucks the $hit out of the car and embarrasses himself in front of a salesman or whatever, starts thinking "wow, maybe I don't want a sports car" or worse...gets a automatic. I also think that fly-by-wire throttle and the delay off dead idle is also a contributor.

Noth hey 1st-2nd even after a new gearbox!
Hi to all you fellow 911 owners, great forum by the way. I bought my 1st porsche 6 months ago from a main porsche dealer . A 2009 gen 2 3.6 carrera , it has 2 years porsche warranty. I've wanted a 911 all my life , though my bubble is now beginning to burst . The car has now gone 38000miles with myself covering just over 2000 in the car. The gear change has been awful since I've first had it , there is a resistance and some times a clunking/ grinding when shifting from 1st -2nd even when the car is warm/hot. The first opc said there was nothing wrong , I lived with it but wasn't enjoying this grinding/ clunking/ notchy experience. So I eventually took it to a different opc they too said nothing was wrong so I asked them to drive the car the next morning when cold. I got a call stating I need a new gearbox and parts were on order from Germany. The gearbox box replaced and I was so excited about picking up my fresh slick 911. They didn't relive the clutch as they said it was ok. On collecting and driving the car it felt exactly the same as always with a stiff clunking / notchy gear change. I wondered of they had even replaced the box!? I had the car up on a ramp to confirm and it looks like a new box but it's exactly the same! I now don't enjoy driving it and the main dealer garage have fobbed me off saying it felt ok on 2 cold mornings when they tried it. I don't like to keep complaining but I'm not happy with my car! Any advice on whAt else it could be or what I can do would be much appreciated as I want to love my porsche that I've spent all my money on.
Thanks
Thanks

Update:
I changed over to GT3 shift console and adjusted the shift cables a little. Not much improvement to be honest.
I adjusted the way I shift a little by not pulling the shifter so much toward the left which helps when shifting into first gear.
When the first gear is blocked I let off the clutch just an inch or so and then I am able to move the shifter all the way to first.
Hope that helps others.
