Default Does 997SSK stress tranny internals at all?

I'm thinking about installing a 997SSK and was wondering if it added any stress to the tranny internals vs the stock 996tt shifter?

thanks

As a general rule, the faster you try to shift a transmission the more wear it can cause on the synchros. Also more possibilities for mis-shifts too. A smooth and precise shift with a regular shifter is usually quicker than fighting a notchy and difficult to engage short shifter. I personally would go with a regular 997 shifter if any and steer away from the 997SSK. That will make your shifts more precise and smooth like butter. It is slightly shorter throw than stock, but also smoother and easier to engage than any shifter out there including the stock 996TT.

Thanks for the reply haulinkraut.

I was already leaning towards the OEM 997 non-SSK and your post helps solidify my decision.

I don't recall any negative comments regarding the OEM 997 shifter...

Kevin told me last week that he has been seeing problems with the 997SSK. I have the stock 997 shifter and it has been a huge improvement over the 996TT shifter.

I have a customer who tracks his car. His gearbox was getting very notchy. He has a B&M and changed to a 997SSK.. When his gearbox came apart he had bent his shift forks.

If you track you car you are better with the GT3 shifter. You can place alot of force on the factory forks shifting.

For the street the 997SSK is good.. However, I feel that the 997GT3 shifter "feels" better, with a slightly larger throw.

The shift forks bent after installing the 997SSK? If so, why would the 997SSK be more likely to bend the shift forks (as compared to the B&M shifter)?

How does the GT3 shifter reduce the force on the factory forks?

Dock take your pick, the damage could have been done with either SSK.

The GT3 doesn't have the short throws as the above mentioned SSK.

The GT3 shifter does have machined aluminum guts. There is less potential force placed on the cable>forks with the GT3 shifter vs any SSK. As you know with a SSK there is no free lunch. The cable and fork needs to move the same distance to move the gear.

Bending shift forks in Porsche gearboxes is not a new issue. It's been happening for 30 plus years. I personally have bent forks causing "myself" to snap the input shaft. That was almost 30 years ago, when I installed/made a SSK kit.

Since we are talking shifters, I noticed there are the metal after market shifter couplers (i.e. Agency Power Part Number:AP-996-300 ) vs the Porsche plastic. Do these cause any of the same problems the SSK does?

Kevin: To be clear, you are suggesting the 997 GT3 console, correct?

I see SunCoast sells it for $350. (if this is the unit: http://www.suncoastparts.com/product...ode=996tttrans)

I have the 996 SSK and have never felt comfortable with the increased effort required. I've often considered going back to the stock shifter.

I have the 997SSK and it feels perfect and not nearly as short or notchy like the B&M. With that said, I think the problem lies in the manner which you shift. If you are patient and shift by the heartbeat (every so slight pause at neutral) method instead of quick shifting and slamming into each gear.

If you track though, and I mean track the car (not 3 or 4 DEs a year) then the standard throw non SSK is the optimal shift housing.

I guess the OEM 997 SSK is ok for regular street duties. Just ordered one through Ryan at suncoast

I agree with LVDell. With my current stock 996tt shifter, the "heartbeat" shift is alot smoother.
