May I ask what was replaced in your trans for 2500.00

See the pictures on post #45 and ready some of my description before and after that post. https://rennlist.com/forums/996-foru...-my-diy-3.html

Pinion bearing, 2nd syncro and I also had them change transmission mount.

Biggest difference was that the noise was all gone, I do tell myself that it shifts smoother as well.

Ouch!! Looks like they did the same as I'm planning to do and reused the input shaft bearing (only replaced the pinion bearing). You can save $2K if you do all this work yourself and buy the VW bearing.

I was very happy to pay $2000 for this. I did some research but realized that I couldn't pull it off, seems like you have to tear down the entire gearbox.The assembly of this gearbox was to complicated for me and gears seems to be pressed on with a super mega press.
here is a thread on how to do it.

Good luck and post some pictures!

The more information the more people can DIY this.

Edit:
Did you already do yours? I noticed you posted something in the other thread?

Ah great, I didn't realize am's excellent thread had also been updated this year, I can see your puller, great idea. Looking closely and I think you have managed to remove both outer races and all the bearings, so it just clamps onto the inner race and drags it off?.

Imo000

Yes, it just clamps to the inner race and drags it off by using and air impact gun.

I'm in the finishing stages of putting mine back together. The bearing is already swapped and the gears are almost all pressed back onto the shaft. Honestly, it looks more complicated than it really is. You do need a level of understanding how to do this but it isn't that bad.

Came across a You Tube 996 transmission rebuild series. Looks like it was posted last summer and shows a lot what it takes to take apart one of these units. This will help anyone in the future that wants to do this work themselves. The episode where the spring loaded ***** are installed starts at the 5:25 mark. Well worth the watch before tackling any internal work.

Good info (but OMG, mute the music). The "stones" in his gearbox are a different shape than in mine were (mine were more rectangular, not rounded). His technique is awesome, I struggled with this for hours and hours. Don't let this video fool you, those spring/ball/stone things are a HUGE pain. Hands down the most frustrating thing I've ever done on any car.

Mine are rectangular too.
Now here is the interesting part if forgot to mention. I broke one of the springs a couple weeks ago so ordered 3 new ones from the dealer and picked them up op Monday. Last night when I was starting to put them in, noticed that the new ones are slightly shorter. About one turn of the coil shorter. Checked the part number on the shipping bag and they are the correct ones. Looks like Porsche updated this part and now they are slightly shorter. This should make installation easier regardless of the method.

After struggling with my nose cone, I found the single online reference to this mystery 13mm bolt and figured my troubles were over....So, removed the bolt and still no nose cone relief!

Anyone know why mine won't come off?

My car is a 2000 Boxster S (6 speed) and my problem for doing all this is that the 2nd gear detent wouldn't come out (and still won't come out) so that is still installed in the case.
My magnet has metal shavings but not sure how much is normal, if any.
Anyway, is there something else that may be holding the nose cone on? Or is it just a matter of those internal pieces in the pics above getting stuck on something?

Got it...

It was a bent detent and broken "shift segment" as Porsche calls it that was interfering with the gear selector.
