Your welcome, and thanks !

Thanks for reviving this thread, I installed the 1st edition of the C6Z06 shifter in my car. While a vast improvement over the C5 shifter, there is still a little issue between 1st and 2nd, will try this as I love the shifter over the original.

I completed the mod today, and it made a difference with my ripper, but I will try a 2nd gasket to see if 2 gaskets are better. My 1st difficulty was finding the gaskets. I visited about 6 auto parts store (including Auto Zone, Advance Auto, Pep Boys, Napa) & none had the Oil Tite gaskets 65277. After some research on the internet, I found that the Napa BK 704-1357 is the same gasket. I went to Napa & purchased 2 for $1.10 each. The other issue was finding the plug on the trans, it was located way up on the top side, not easily seen. Is there a difference with the location of the plug between the 98 & the later model vettes? Then I had an issue with breaking loose the plug, I need a breaker bar to loosen the plug on the trans. I did not have a 15/16" socket but the 24mm fits perfectly. This is a good mod because now I do not have to get rid of my ripper. Thanks. :thumbs::cheers::cool:

Just did this mod today...I didn't notice much of a difference (MGW shifter), but I only drove around the block. I'll drive it more and post back.

Can someone please explain to me how backing this detent bolt out a little with a gasket/washer can ease putting the car in reverse? Im still learning about c5's thanks

Wow I had forgoten about this mod. Did this on my 98 many years ago and it made a big difference. Ill have to remember to do this next time I have the Z in the air :)

Who came up with this modification?

I think it started in 2005 from Greg of AntiVenom inc in Florida (A Corvette/GM Tuner). Not sure though...

Just something I read on here and other forums years and years ago.

I just thought I would bring it back to life for all the new-b's on here.. :lol:

Just did the mod today. I've got the Ripper on my car and I started with one washer, test rode and noticed an improvement, then, since it's so easy to change, tried two, and actually like the feel of 2 better. But my Ripper was really notchy and fairly hard shifting. I am also going to change to Amsoil and realign my shifter. This mod was a great improvement and I wish I'd done it a long time ago. Can't believe how easy it is. Once you find the detent, it is a 10 - 15 minute job start to finish, including getting in the ramps and jacking up the rear (assuming you don't have a lift). Thanks for bringing this mod back. :cheers: Zuti

Haha I thought that old thread seemed familiar. I remembered that big debate with boosted_Z06. Sure enough I have the last post in that thread. :rofl:

Wait.....does that make me a thread killer? :(

Hopefully not this time...

If you did, .... then hopefully this will keep it going... :D

I hope not too. It really is a great mod. I drove my 98 around for two years after doing that mod and loved how easy it made quick shifting.

However, just because you CAN powershift 2-3 doesn't mean you should.....especially if boosted....my poor 10mm torque tube didn't survive for long :lol:

Not that I'm lazy to go to the store but I like when parts arrive in the mail. I will take two just pm a paypal addy. Thanks!!!

No Chicago1, your pretty lazy :rofl:

Jk man :lol: :cheers:

Modded my Z today. I just did about 1/16" this time around. Enough to make it smoother, but not enoguh to completely eleminate it. Its just right. Thanks again for reminding me of this mod! :cheers:

Glad it worked for you ! :thumbs:
