do you guys think swapping the fluids. to either amsoil or w.e. or lucas.

now you make ask why not RP. but i decide to ask a shop up here AWD Motorsports and they told me that Royal purple is nothing but royal purple crap. its just purple..

so yeah >.< Sorry summit :(

FYI, I just had my 2010 LT M6 fixed under warranty for the same problem. Did the friction point of your clutch drop towards the floor like mine?

#PIP4774A: Soft Or Low Clutch Pedal Hard To Shift
Transmission Grind When Shifting Or Unable To Shift -
(Apr 19, 2010)

Condition/Concern:
Customers may comment that the clutch pedal is soft, low or the transmission is difficult to shift
or cannot be shifted into any gear particularly when at a stop with the engine running or the
transmission grinds when shifting into any gear. Technicians may find that the clutch does not
completely disengage when the clutch pedal is depressed. This concern may be caused by loose
clutch pressure plate bolts.

They replaced the plate and the bolts:

24255749 Plate 1
11570903 Bolt 6
89021297 Adhesive 1

Mine does this when the cars cold. Engages by the floor and have to double/triple clutch for first leaving my neighborhood.

When they swapped my trans they put new bolts and shifting felt better than before service because these gears arent worn yet. I havent forced any shifts so i dont get a grind anymore but i still have to abort shifts to save face/avoid grinding when its not fully disengaging. Can you confirm if this is what you were seeing? It looked like they got you a new pressure plate also right?

I still dont get why a loose clutch pressure plate would make it not disengage. For some reason in my head i thought it just pushes the disc into the flywheel so i thought itd slip if loose shows how much i know about this stuff???

So are folks with new pressure plates and bolts installed still having issues with 1/2 high rpm shifting?

You're experiencing different issues than what I and some other people had, so I'm not sure if a fluid change will help. At worse, you lose the price of a fluid change.

Did they actually try/test it? What proof do they offer to back up their claim?

Sounds like nothing but an opinion to me.

What I'm offering is actual real life before/after experience. The reduction in grinding on aggressive 1/2 shifts was instantaneous and dramatic.

You can take that to the bank ...

I saw the test, but immediately invalidated it seeing how Amsoil was the one actually doing the testing.

It's not an independent 3rd party test by any stretch of the imagination ...

BP went after RP a while back over their lofty claims:

Amsoil quotes the BP RP spat here:

The part that I dont like is where it says none of RP products are certified as of 9/09 even though they show the logos on the bottle.

no issues here at all but suscribed for future reading

In the test affidavit the test were conducted using ASTM, SAE and Federal Test Method Standards that where sign by Dave E. Leiter Director of Lab testing for Amsiol. If these test were not accurate or fudged to benifit Amsoil they would be lawsuits and legal actions taken, since 2007 when these test were made I couldn`t find any suits or action brought against Amsoil for being inaccurate or even the test themselves being disputed.

Given the name brands that were included in the test I`m pretty sure one of them would have disputed or brought action against that test.

Sorry, I don't buy it.

For example: Companies regularly put out parts with "certified" dyno increases, but when people test the part themselves much of the claimed hp mysteriously "disappears".

And in the scientific community, a company trying to sell something based on the merits of their own testing would simply be laughed out the door.

Independent testing is the only viable solution to weeding out claims versus reality (which is the same reason why Jannity's CAI tests are so incredibly popular).

But the important factor here that is being lost is that I actually tried the product myself. I was told by a C5 member that adding Royal Purple to the trannie made an immediate and drastic improvement to the 1/2 "crunch" problem.

I confirmed that as fact, which for me ends any discussion regarding it's validity. It performed as advertised ...

The objective of this thread was to make owners and GM aware the problem is widespread (see poll), have them identify the design issue, and provide v6 m6 owners with a lasting repair.

With the amount of feedback in here we have a basis for our complaints when we go to our dealer. It throws out their ability to say well your just getting used to the car, it'll get better once it breaks in, you must have 10k on the car for a trans swap, etc...

Please try to be respectful about the purpose of the thread. Share constructive information relating to the transmission bind/grind issue you have and keep us posted with any solutions that GM is suggesting/offering.

I have not done a very good job maintaining the list in the original post. I am planning to reread the posts/PMs and update the list later this week. Luckilly I put the poll there so the thread continues to gain feedback even when the OP gets lazy!

Thanks,

Put me in the bind category, 1st to 2nd high rpm, occasional crunch. I now have 10k miles

[SUV2008]

I also have the high rpm crunch from 1st to 2nd...5,600 miles here. Took it to the dealer with about 2,000 and they said they wanted to wait til I had more miles on the car to see if it loosens up.

[danrc28]

Mine almost always does this on hard throttle....damn i was getting scared that I was the only one with this issue!........I usually get a grind noise and cant shift into 2nd. 24K

I have read all 22 pages of this thread, and didn't see anything that directly relates to my situation, so I posted a new thread.
I have a 2011 Camaro v-8 2ss 6-speed, and it grinds from 1st to 2nd under high acceleration when shifting quickly. The problem started shortly after it was brand new, and still does it currently. I'm at 1100 miles now.
If this is the same as you, then post to this thread.
