Its possible it is low and/or needing to be replaced + there is always the possibility that someone put in an inferior fluid (I have read people post they immediately noticed a degrade in shifting after switching to something other than the Porsche fluid).
Leading evidence: 'Replace + there is always the possibility' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Inspect from underneath' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Changed the gear oil and had the gbox detente out in.

You need to inspect from underneath to give us more info.

If you are planning on replacing bits, start with the cheap ones.

I would recommend replacing the transmission fluid.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

From second, sometimes a bit of a grind in gears...sometimes the tranny seems to slip back...and third somewhat the same...
The car has under 30,000 miles on it...I can't believe the transmission is going.
Anything to service for this?
Thanks!
Common problem -several causes.
1. shifter cable loose on side of transmission.
2. 2nd gear dog clutch /synchro worn but usually at 3x your miles.
3. sloppy engine/transmission mounts
You need to inspect from underneath to give us more info.
Popping out of second gear is a widely-reported issue with 996 transmissions. If treated early, you can apply GBox's "second gear detent" - but if it has been ongoing for too long, there will likely be transmission damage.
I'm assuming this is a manual car.
You are correct but recently CMS and Gbox have been contradicting that saying the old detent/arrestor will eventually cause more damage.
There are 2 devices
1. detent
2.shift arrestor
Here is the latest I have for others to play with:

I wish either or both companies would write a detailed description of the issues and why their mutually exclusive alternatives are better and what exactly was wrong with the old ones. I have the old design f detent so am anxious to know if I should replace it even though it has zero miles.
Maybe your clutch isn't fully disengaging? If you depress the clutch and shift through the gears with the engine off does it still grind? If you're taking it to your indy for the detent, I'd have him/her take a look at the slave cylinder.
Mine popped out of second when the gearbox was cold in under 40F ambient temps. It would go to a half engaged position that would grind second. Gbox detent seemed to fix the issue on mine.
If you are planning on replacing bits, start with the cheap ones.
I would recommend replacing the transmission fluid.
If it is old replacing it will improve shifts.
Millemiglia was referring to the fluid inside the transmission (gear oil). I believe the service intervals is around 100k miles (don't quote me on that). Its possible it is low and/or needing to be replaced + there is always the possibility that someone put in an inferior fluid (I have read people post they immediately noticed a degrade in shifting after switching to something other than the Porsche fluid).
I agree with the advice above, start with easy things like checking to make sure the clutch is fully disengaging, transmission fluid is topped off and good, shift cables are operating properly. All easy fixes compared to dropping the transmission out of the car.
When my car is cold 2nd seems a little harder to get into, but when it's fully warmed up it's fine. After doing a search it seems like the 997 guys experience this as well and just call it normal. Others have said it's a bad synchro which is probably what worries me most.
Ditto... my stick seems a little stiff in the mornings too, but once it's warmed up, it's works great. Is it just me, but when the stick is cold, it doesn't want to go in the right slot without forcing it? When it finally gets hot, then it's full speed ahead. WeeeeEEEEeeeEeeeeeEEEEEe!!!
Changed the gear oil and had the gbox detente out in. Much easier shifting now, more of s slot feel and never slips out of second when cold.
I notice it shifts into first best when near stationary. I guess it's easier on the synchromesh. So now I put the clutch pedal down and brake and shift into first once I stop, to prepare for the next start from stationary. Much easier time of shifting this way.

So which oil did you use ? Shell Spirax?
