You're right. Back with my '06 Cayman S I learned that nothing went over 3k until H2O temp got to normal. I will take this opportunity to replace the cables though. Even when warm I don't like the overall feel. Had not heard of the Shift Right brand. Only about 50 bucks less than the Numeric. Anyway, PTX (gold $ in a bottle apparently) ordered.

I bought my 09' C4S last September. The shifting was really poor. I went through and re-greased the shifter and installed FF cable ends. These made small steps in improving the feel and reducing the notchiness. However, after I looked through the stack of receipts I had from the PO, I noticed the shop that changed the trans fluid used Redline a few years ago. I've had no issues with RL in some early manual Audi's and VW's I owned. However, the best improvement happened a few months after I switched over to the factory PTX Porsche Fluid. The shifting progressively improved after putting about 1000 miles on the car. Now, I actually think it is really good!

Back when I did my PTX research, I found the two Porsche dealers near me used Delvac. They were totally unaware that spec'd right in our manuals was a different formulation oil.... PTX GL 4.5 is written right there. I assume it is noted in their procedure manuals too, although I am not sure of that. So... even if a dealer serviced the car does not mean they did the correct thing.

PTX and thorough clutch bleed did it for me, using stock cables. About 40% improvement from each. Clutch bleed ensures that between shifts, the clutch is completely disengaged, so that the cogs are not loaded up with residual torque transfer loads.

The transmission needs to warm up its fluid.. Remember it is something like 90 weight.. I think the recommendation by Prairiedawg is good advice. Though unrelated, it gives a good measurement of time.
I also noticed that when I let a friend try my car last week (I know, I know) ,He was shifting like an American car and just trying to slam the box, It took me a while to get him to slow the shift down, and feel it into gear.

Is the PTX oil worth it as my 2010 911 has this same issue? Hard getting into gear w/o a feel of spinning teeth once and a while and the notchiness all the time when cold. Once warmed up everything is like butter. Thanks in advance for any input.

It's a simple enough change (drain and fill, accessible from the underside) with the potential to make a big difference. I think it's worth it.

I changed my motor mounts at about 100K miles as one was sagging a bit... did not effect shifting one bit and I had a jammed 1st gear for years before and after. Amazing how our experiences can differ. Same for my installation of the Numeric shifter... no difference in shifting (just a way better feel)... although I did not use the alignment tool, I just eyeballed it... but as I noted above, I can't see for the life of me how shifter position can affect anything.
