Yeah. Mobilube PTX. Usually only available in a 20 liter jug. Such a popular solution Suncoast Porsche offers it in 1 liter bottles. You will need 3. It's Porsche approved but most dealers use Delvac (also approved). Both are 75W-90 but Mobilube blend works better at lower temperatures.

 

Bumping this bc I have this 1st gear problem in my 2010 base manual. Has anyone successfully gotten a dealer to fix this issue? I know I can try the PTX fluid change, but I have a CPO warranty and would prefer to have Porsche pay for this vs me buying fluid and paying an Indy to change it. Thanks!

 

I changed the gear oil, installed numeric shifter and cables. My issues are near gone. If and when i have an issue I double clutch it and it goes right in.

 

I've had success with this...

 

Thanks guys, I'm glad there's a potential solution, but I'd like to try to put the cost on the CPO warranty to fix this, vs. trying to troubleshoot myself. Has anyone had any luck convincing a dealer to do anything? Or do they just shrug and say "they all do that"?

Other than this slight sticky 1st gear annoyance, I'm perfectly happy with how the car shifts, so I don't feel the need to mod further with new cables or a short shifter. It's a tight and smooth gear change.

 

As I mentioned , double clutch it. It happens because the synchros are not alighted. Double clutching it will align then. It will go right in.

 

I hear you, but I was hoping for a better solution that I can ask the dealer to undertake using the CPO warranty. I learned to double clutch years ago into 1st on my 2002 WRX manual, which had nonexistent 1st gear synchros and a pretty crap 5-speed gearbox. I’ve had no 1st gear entry problems since then on my subsequent BMW e46 330ci, or R55 Mini John Cooper Works. It seems a little silly that I now need to double clutch in my new to me fancy Porsche. I also still don’t understand why some people have this issue and others are completely fine.That seems to indicate some trannys are defective?

I’m loving the car other than this issue, and the transmission thump that I hear in 2-3 shifts (which I read is also “normal”).

PTX... see my earlier thread. It works for many people.

I did have correspondence with one guy who opted to get his 1st gear fixed through the dealership.... he said, the dealer said, there is a repair kit for this issue... but he didn't know what it was. This was the first and only time I heard of a dealer noting and issue and a fix. I do remember it was very expensive... just can't remember. I don't know what his outcome was.... darn, I lost track of him. I wanted to know what that gear, sycnros etc looked like. I want to know about the wear. But... oh well.... PTX is a much cheaper fix anyway.

Same problem. I refreshed/updated my engine mounts (function first). It hasn't completely gone away but it's rare now. I have the transmission mounts they sell too, I'll give them a try this winter. Incidentally, had a 914 years ago and it happened at every stop. My '82 SC also has the problem, even after a rebuilt trans.

 

Yeah I saw the PTX thread but don’t feel like spending the cost if I can have the dealer address it under the warranty. I’ll ask the dealer to look at the first gear issue and transmission thump at the next oil change and see what they say. I can live with the issue until then, it’s not a huge deal, just a slight annoyance.

 

Interesting, I guess this may be a Porsche “feature?”

 

I had this exact issue didn’t matter if the car was warm or not. Mine was really bad - could not get it to go into first at all. I though something was significantly wrong - bad.

Numeric Shifter fixed it almost entirely. And improves shifting and the fun 100 percent. Sometimes it’s resistant but quickly
shifting into second clears it to shift into 1st immediately.

However, with the shifter you can still force it into first whereas the same pressure would not have been sufficient to engage first with the stock shifter. If that makes sense.

I don’t have this issue at all with my 991.1. I suspect the stock shifter has a lot to do with the slop.

 

i have the same problem shifting into first, but like others here have said, i just been assuming its because of the synchros. i just do a shift from 4 to 1 with the clutch in, and this seems to line them up well enough. or i just put pressure on the shifter into 1st with the clutch out, then just clutch in and it'll go in just fine.

what i dont undestand completely is why change to a numeric shifter would fix this. i guess the stiffer numeric cables (if you choose to get them installed) help force the gear in?

 

A trick to solve this (at least worked with my 996TT with 997 SSK): When it won’t quite go all the way into 1st gear, just hold the shifter applying the same amount of force you normally use, and let off the clutch the tiniest little bit (maybe 1 cm). The shifter will just slide in gear. This requires a bit of finesse as you can stall it if you go too far obviously. And it may be harder to modulate with the boosted slave (I had GT2), but it worked 100% of the time and much faster than re-spinning the synchros.

I’d still spin the synchros if I had time, but when you’re first in line at the light with that angry SUV driver right behind you, it’s the quickest way to get going.

 

and to this spec seemed to help this problem on my 06 C2S with 100k+ miles. Could be that the weather has been a bit warmer too though, will report back in the winter.
