You can change the fluid if you want. It is not due based what Porsche recommends but it is close.
It can't hurt but I don't think it will help.
I'm not sure how cables can not be completely attached yet the shifting work. From what I recall the connections are not something that can be half connected. Either they are secure or they come apart and the cable is loose and the shifting just doesn't happen at all.
If you have not had it done in a while have the brake and clutch fluid flushed then bled. I have found letting this go can cause clutch and shifting issues. Braking was unaffected before the flush and not improved after but clutch action and shifting action afterwards were like night and day compared to what they were before the the flush/bleed.

I'm not sure either how they could be partially attached. Unfortunately I didn't see it, my indy took care of it while doing IMS.
I think my plan of attack will be: double check both cable ends to make sure they are properly secured. Trany fluid - it's assumed to be 16 years old at this point, even if the mileage isn't quite where replacement is recommended. Probably brake and clutch fluid as well, and given the uncertain maintenance history (car came from a dealer lot with no history), that helps give me a service baseline anyways. Then see how it is. If the problem persists then we go deeper.
Thanks for all the tips. Will update when I have something. I probably won't have time to tear apart the center console to look at the cable ends until the weekend or next week.

Be sure you have or do both the brake fluid and the clutch fluid flush/bleed.
As I touched upon earlier I was having problems with my Boxster, getting the car to move off from a stop smoothly, and shifting almost always seemed to involve some minor crunching of the gears.
This was quite contrary to the way the clutch worked before and the shifting worked before.
However, with I can't recall the mileage now but close to 280K miles on the original clutch and transmission -- albeit with fluid changed at the scheduled intervals -- I just kind of believed the clutch -- and maybe even the transmission -- was just wearing out.
At the dealer to discuss perhaps booking the car in for a clutch job the SM looked up when I last had the car in for a brake/clutch fluid flush/bleed and noted it was 2.5 years earlier. I'm thinking how much difference can a half a year make? I mean the schedule is every 2 years so another 0.5 year?
But a fluid service is cheaper than a clutch and I'm willing to throw some money at a fluid service if there is a chance it stops me from doing something more expensive. Thankfully the fluid service cured the clutch and shifting ills.
Be sure the shifting linkage is ok. I guess it can be marginal and could affect shifting action rather than just one losing shifting altogether.
Have the tranny/diff fluid replaced. It is close to being due and many techs advise changing this fluid before the IIRC 90K miles at which the factory schedule calls for its change.
But then have that brake/clutch fluid flush/bleed done.
See how this affects or doesn't affect the clutch/shifting action before you move on to more involved servicing/repairs.

A tranny/diff fluid change can't hurt. For my 2002 Boxster with its 5-speed it is about the least expensive service there is. Fluid and 0.3 hour labor. Often the dealer gives me a break on the fluid price, too. Once I got it for $5/liter when the dealer and some extra left over from warranty work.

Yes, the Porsche specs are 90k miles on tranny fluid change, according to the docs I have.
Agreed with your feelings on fluids - it's usually a great and inexpensive place to start.

How much is a zip tie? Like 20 cents?

It decreases the leverage, which shortens the throw. It's adjustable (multiple holes). If you already have the B&M shifter in the console, this one will make the shifts even shorter. Not sure if it's a good idea.

Cable is zip tied at the tranny, looks secure on the other end. Fluid changed. And the issue persists. What worries me is the downshifting issue - the occasional grind on downshift from 4 to 2, with the clutch pedal all the way down, makes me think synchros. I can't imagine another likely cause.
I'm going to get a second opinion from another indy (my guy isn't a transmission guy) before doing anything else.

Not a typo. It is closer to 293K now.
