This sounds like what I've been through with my Boxster. I have a 2002 Boxster S, just passing 30K miles. I've done everything you've mentioned in stages over the past 18 months.

I think the main reason the shifter feels like garbage to me is I grew up on Japanese imports in the 80's & 90's. I learned how to drive a manual in an RX-7, later had a Nissan 300zx, and then an RX-8 when i was older. I think those cars spoiled me a little bit as to what a shifter should feel like. The RX-8 is the best shifting car I've ever driven. I think it ruined me.

This is a long read. Short answer: Start with a gear oil change. Use genuine Porsche gear oil. Maybe do it twice with some driving in between.

Here's everything I've tried and my thoughts on the result. My Boxster takes some muscle to shift when cold. It eventually smooths out which i think is from heat built up in the transmission from gears spinning. It's more that just warming up the engine (but that does help). Sounds like your experience and that of others.

1. Short shifter (no-name from Amazon) and new bushings (Phoenix Engineering) in stock plastic shift cage. Felt a little better once warm (placebo effect?) but no difference to the clunkiness when cold. I really didn't like it, Overall waste of money for me ($150 total) because of where I went next.

2. Numeric Racing shifter. Improved overall but still wrestling into 1st and 3rd when cold. Very nice shifting when warmed up. A little tedious to set with stock cables. Numeric can be adjusted to tall, regular or short on the handle. I didn't like the short and keep it in the middle (stock-ish) spot. The Numeric really narrowed the shift pattern. Not as much sideways motion needed 2nd to 3rd or 4th to 5th etc. Significantly reduced the slop. But again, didn't eliminate the clunky cold shifts as much as I wanted. There was noticeable improvement though. No placebo effect this time.

3. Drain and refill transaxle gear oil. I confirmed with the shop that maintained the car for the previous owner they once changed the gear oil and refilled with Redline Synthetic. There are a lot of opinions on the proper gear oil for the Boxster and Redline specifically. I don't want to enter that debate (because I just don't care). I drained and refilled with the recommended Genuine Porsche gear oil I found from Suncoast. This made a big difference for me. Still not perfect, but much much better.

4. Numeric Racing shift cables. I just put these in last weekend. It is a big improvement from where things started. But STILL takes some force when cold in the up gears (1, 3, 5). Shifting is significantly improved when warm, just like previous things. I haven't gone on a really long drive yet to build up a good heat soak in the transmission. But it does get significantly better after about 10 minutes of driving from cold.

My next and final thing to do is to repeat the drain and fill of the gear oil. I want to make sure all the Redline has been flushed out, and I think I may have overfilled slightly when I did it the first time. After that, it is what it is. I can live with it.

None of the work was very hard to do but the cables were a giant pain to install and get attached under the car (take the wheel off). The gear oil stinks like crazy, I don't recommend getting it on anything you care about. If you are not a member of your local PCA chapter, try joining. You might meet some people there able and willing to help. Some cities even have do-it-yourself garages with lifts you can rent to do work.

Overall, I've spent well over $1000 and the tough clunky shifting when cold persists. It's maybe 30% better than when I started. It's moved around each time I tried something. 3rd gear got better but 4th gear became tough. That sort of thing. Once warmed up, I think shifting is definitely 100% improved over stock. But aside from being a little sloppy that really wasn't bothering me in the stock setup.
