Hey, friends. I made a 2-min video comparing the stock shift action vs. Numeric + Numeric cables.

Let me know if you have any questions. IT'S GOOD!

You may have just cost me some money.

Been thinking of doing this for quite some time.

I installed numeric shifter the first month of ownership. The stock plasticky shifter is honestly horrible. Changed the transmission fluid as well and I would say it's about 9/10 there to my old S2000 while I'd put the stock shifter at 4/10.

Ah I didn't think to do the trans fluid. How much is that to have done? Or is it an easy DIY? Do you think that would affect the feel of my shifts? My car is a 2006.

It was $175 for a local shop to do it. Porsche has it listed as a 120k miles or 10 yr routine maintenance item. I didn't see it done in any previous records for my 2009 so it was one of the items I wanted to have changed along with all other maintenance items. It did smooth it out a bit so I imagine it was due for one.

Assuming you have a manual transmission car, changing the oil is a pretty easy job but you need jacks stands or a lift. You need to remove the "triangle" metal plate and you don't want the car resting on the suspension when you pull that off or you can change your alignment. Somebody did a very nice write-up on how to DIY that job. I saved a copy and can forward to anybody that wants it.

IMO, left and right play when in neutral will always be about the same WRT OEM and numeric shifters. however, the resistance to left and right movement may vary significantly due to the spring rates used. same for fore and aft. the difference in the shifters (numeric vs. OEM) in other respects is due to the frame material used. OEM is injection molded plastic, and is flimsy in comparison to the numeric CNC machined aluminum. the difference is obvious once you've held both of them in your hands. that's not to say some people might prefer either one over the other...

If you want to make it really easy, you can use a 2-1/2" hole saw to drill a hole in the aluminum plate. This is something Porsche should've done and makes accessing the transmission drain super easy. It's just a fairly flimsy aluminum gravel shield so you're not hurting anything by doing this.

I've done the job twice. The first time I did all the work to remove that plate, the second time I just drilled the hole and then plugged it afterwards with a plastic hole plug. I'd strongly recommend doing it the latter way.

2-1/2" hole plug:

great to know! can you detail exactly what felt smoother? was it smoother revs/downshifting or?

22Pana

that would be great! thnx!

The numeric short shifter made the shifts much more solid and obviously shorter with the CNC machined aluminum housing as another poster mentioned. However when the car was cold there was a bit of notchiness going into 2nd and 3rd. After changing the transmission fluid, it felt the notchiness was smoothed out and super satisfactory when warm.

I like your style, MrMoose! Work smarter, not harder.

Mine's the same way after putting in the Numeric cables and stiffening the rubber buffers in the left transmission input. I suspect these gearboxes are just a little balky when cold and it's a lot more noticeable when you take out the slop.

I'd also suggest sticking with the Porsche gear oil, which I believe is made by Mobil. I tried Redline 75W90NS as a recommended replacement and I think that was a bit worse in the cold, ended up going back to the Porsche stuff.

It works very well. I didn't come up with it, there are some details in this thread on where to drill the hole:
