So I just traded a 991 c2 for a 997.2 c4s cab and I couldn't be happier. I absolutely adore this car, even more than my first Porsche (a 987.1 Cayman S). Quite often if I am driving and put the car into neutral at a stop and then try to go into first I can't, it just won't go. If I then let up and depress the clutch pedal it will usually let me put it into gear. What in the world is going on and should I have a mechanic look at it? The car is CPO from Porsche so.....

How old is the trans fluid?

Look into purchasing some Mobilube PTX and trying that, it was the factory fill for 997s.

A different solution or the same 'change fluid to something no one carries locally' solution?

Thanks, guys. Will have the fluid changed and see what happens.

Mine does that now and then. Just did it yesterday, but now when I come to a stop I make sure it goes before the light changes to avoid embarressment.

I'm not sure it's that uncommon for many manual transmissions to do this. Several ones I've had over the years would occasionally be hard to get back into first at a stop light. When it happens to me, I generally drop down to second, then first and it usually works. However, I also think it's probably a sign to change the oil.

It's not just a fluid change, it's a fluid change with Mobil PTX - has to be that specific oil.

So do you try it once and then put it back in neutral until you see the light in the other direction change to yellow, or do you sit there in first with the clutch depressed? The latter is terrible for the throw out bearing.

I have PTX and it still does it now and then. Very disconcerting when the light turns green and people behind me start honking, because even though I know not to try forcing the lever into 1st, that's my instinctive reaction. The best way is, with the trans in neutral and clutch engaged, blip the throttle once, throw out the clutch, shift into 2nd then 1st. It should snick right in.

Yea, I always wondered if there is some wear in my transmission dogs that is being masked by the PTX. Porsche fill is every 120K miles..... for my car, it appears to be about every 30K miles...and it really works. Was Porsche just way off? Did Asin use inferior metal in there? Who knows.... did anyone tear down a transmission with the first gear jam and actually look inside? Appears the 1st gear jam is pretty common and PTX appears to help most but not all with the issue. At least changing the fluid to PTX is way cheaper than gutting the transmission.

Back into neutral for sure after playing with the lever. I rarely sit with clutch in if I can help it. Do appreciate the thought though. Thanks.

Had the PTX replacement today at a Porsche dealer. She is shifting so much better now! Thanks guys

My 2010 c2s w/ 40K miles occasionally 'balks' going into 1st gear. What I've found that works from me, is to pull it down to 2nd gear, then it goes back into 1st gear with no issue.

cool flash

Had the same issue and made me sell the car after only 1.5 years.

If fluid change does not cure this then it is likely synchro rings and apparently parts are hard to get for those Aisin gear boxes.

I wish you luck.
