The CMS part is the true fix.. Nothing else is needed, Roger did his homework as he did with all his products.

Earl and JP, why would you pay 199.00 for a piece that does exactly what the 8mm ball does? I mic'd the ball from porsche and it is 7.90mm

Tim, thanks for the write-up. For me, I've already got a g-box detent in the trans ready to go back into the car. I've never had a popout issue, just put it in for insurance. Just want to be sure it isn't detrimental as Orbelo may be suggesting.

Same thing here, already got the Gbox mod. But I bought it at the beginning when it was only around $60.00. But I was worried about the "DO NOT USE" ;-)

Thank you for all your contributions here, much appreciated.


I never had any issues but installed the gbox item four years and 5k miles ago. No problems with that item ether. I paid $69.00 for it back then.

I called them to discuss the cost involved and never got a call back from Stanley. BTW this was the second time the tranny had gone to Gbox in 12 months... The first time around I broke the 2nd gear which he supposedly fixed with 996tt gears, but for some miraculous reason it was still poping out.

I obviously didn't send the box back to them and just drove the car until the problem got worst (2nd) gear pop. As of about a month ago, I replaced the 2nd gear again and went with the CMS part. The second gear now goes in and stays in for good. BTW, if you have the Gbox dedent and get the CMS part, DO NOT Keep the Gbox dedent in there. It counters what the CMS part is supposed to do and the second gear will pop out. either do what Tim has written in this thread or get the CMS part.

What kind of sealer are you using, will teflon tape do?

You will need to remove the panels that cover the trans also may need to lower the trans.

Tools: 13mm socket, 8mm allen, small magnet and some sealer.


The trans



the plug thats need to be remove in order to gain access, bolt needs to be removed first.



8mm allen needed to remove plug.



Plug out, clean sealer off.





Use the magnet to remove spring and detent





Now the big trick.. I add a 8mm ball that is a factory part to pre load the spring a bit more. place the ball inside the detent and insert the factory spring on top of it. This mod will make the shifts feel solid and firm.



Here is a before and after the 8mm ball





re install the plug with a little sealer on the treads and then put the bolt back in the trans case. Re install the under body and enjoy the fruits of your labor!

Here is the part number for the 8mm ball.

I have the Gbox detent in my gearbox and have over 50 track days on it since without any issues. I paid around $80 for it. With that said, a couple of years ago I have visited Gbox at their shop and spoke with the owner. What a clown. Shop was dirty and disorganized and Stan's knowledge was sub par. The only thing he was good at was criticizing other shops. I wouldn't let these guys get within 50 feet of my gearbox.

I am also not a fan of GBox but the detent does work as advertised. If your car is experiencing 2nd gear pop out already the detent will not fix it or might but temporarily. Its a preventative mod to keep a healthy trans from developing 2nd gear popout.
