Anyone heard of this one, My Z06 vin 0499 shifts fron 2ond to somewhere between 3rd and 5th, this spot is nutural, go figure, they have been trying to fix this since Dec and no joy, Adjusted the linkage and just changed the transmission. Still does the same thing. Trying to get an new car under the Cal lemon law...But GM says sorry this is a limited production car and you cannot have another...

I have run into similar problem but have been relating to it as operator error. This shifter takes waaaaay less side force compared to the Hurst shifter in my 02 vert. Once I remember, I'm fine. I saw it posted here somewhere that if I keep my thumb off the top of the shifter and push it straight forward with the heel of my palm, all is well. Mostly for me it is just being conscious which car I'm driving so I don't screw up.

I hear you Doug,

It's not easy driving this thing and not having the urge to 'grip and rip' like the Hurst. The Hurst is so notchy and thick on the bottom it almost asks for it. The only drawback to the Hurst is the extra noise it lets in the cabin due to the lack of insulation compared to the stock.
But the stock shifter is fine if you don't man handle it, like swinging a Driver on the golf course, loosey goosey!

Learn how to shift! Or else sell it!

Sounds similar to a friend of mine's Z51 06.I was with him twice.It has done it 3 times.It may not be the same.When he shifted from second to 3rd at high rpm the shifter was fully engaged in 3 rd gear.He let the clutch out and nothing.there was no 3rd.He could freely rev the engine like it was in neutral.Once he took it out of 3rd and put it back it was fine. Is this the same as you are experiencing?Everyone told him learn to shift also.I know for a fact in his case it was not a miss shift.I was there.It is bazzar.

Many new C5 owners have some trouble missing gates when shifting.

The central reason often, but not always, is the hand position on the shifter.

My advice is alway keep your thumb OFF the shifter.

Pull the shifter with cupped fingers (no thumb).

Push the shifter with the heel of the hand, no fingers.

To go 1-2, pull the shifter straight back (remember cupped fingers and no thumb.)

To go 2-3, push the shifter toward the radio (remember heel of the hand and NO thumb). This will allow the strong centering springs to find the 3d gear shift gate.

Hitting the no-man's land between 3d and 5th is almost alway because the driver is gripping the shifter firmly with the whole hand, That hand position introduced lateral directionality to the shifter movement and overwhelms the centering spring, forcing ithe shifter wide to the right of the 3d gear gate.

So, suggest changing your hand position and see if that corrects the problem.

I have upgraded from the C5Z to the C6Z and not encountered this problem at all. I am sure as Ranger says it is all in the shifting technique.

Ranger - I was not referring to your post at all.....I think your comments are very constructive. It was another's post I thought contributed nothing except possibly inciting an argument. Anyway, please accept my appologies I did not mean to offend you!!

Best Regards,

Ranger

Sorry, Bob Schaefer. I missed the post you were referring to. So I deleted my whine response to you.

Hey guys,If you read my post carefully could anyone explain this situation?Please don't tell me it is a missed shift or the gate was missed unless there is a 7th gate in a 6 speed.The shifter with out a doubt was in 3rd gear gate all the way.But there was no third gear.It was just like neutral.we drifted about a mile or so free reving the engine.Once you pull it out of third and put it in any gear it was fine.
I witnessed it twice and it has happend to him a 3rd time.There is no noise,no difference in the shifter feel or clutch feel.
I do believe there is a bazzar issue with some of these trannys and it is seldom enough that nobody knows the answere.

Ranger

As the shifter moves the tranny through the gate and seats at the rear of the gate, it gives sensory feedback, generally two clicks felt through the shifter. Your description indicated you are certain it was fully seated.

Then, if the engine revs freely when the clutch pedal is released, I'd focus on the clutch as the offending issue. If it's been subjected to a launch and then a strong 1-2 shift, it may be overheating due to excessive heat from driver slip or from another form of malfunction. But either way, it could be that the pressure plate is remaining in the open position until the clutch pedal is cycled a second time.

Gee I drove a Ford Ranger truck for ten years “standard” and recently went into a car buying frenzy. Having driven the truck and got right in the Z (after trading/driving a c6 a4 for a few months) and thought man what a nice shifter this is. Have had absolutely no problems at all. Plus my wife drove a Ford Escort again “standard” for ten years – she can shift the Z much better than I can and never makes a bobble. I sometimes “not often” will forget what gear I’m in, but have had no problems with the shifter.

But I can see where if some previous Vette owners had a different shift experience they could be use to a style of shifting that is not compatible with the way the shifting needs to be done now with the Z.

I know carczar, and he's NOT a "newby" Corvette owner. I don't believe it's a driver error situation. I've seen others post similar problems with thier transmissions in the C6s.

So you can hold the "learn how to drive" comments!

The C6Z06's M6 tranny/shifter combination features a strong centering spring that causes the shifter to align itself on the 3d-to-4th gear axis.

This tendency is stronger than on previous C5s in my opinion. If overlooked, this characteristic will lead to missed shifts. That's where correct hand position comes into play.

On Carczar's car, it is actually popping out of gear, this is after the transmission is engaged in gear, then while driving it pops out of gear.

There is a conflict between what carczar says are the symptoms and what 3charmed says carczar's symptoms are.

If the tranny has been changed and the shifter still misses the gate into 3d gear, then that strengthens my view that it's most likely a driver issue.

If the new tranny is popping out of 3d gear, all the more reason to ensure the driver properly seat the shifter all the way to the end on the travel in the 3d gear gate.

The "strong" centering spring Ranger is referring to is actually a full 360 degree rubber bushing which encapsulates the pivot ball of the shifter. I have occassionally noticed the tendency for the shift from 3rd to 4th to be difficult similar to not wanting to go into gear. I just put back in neutral like the old double clutch routine, then gfirmly and commandingly pulled down into 4th. It may seem a little unorthodox, but you just have to do it.

Ranger's technique for shifting works, so practice and stick with it (no pun intended).

Also, installing the shifter detent space washer on the detent spring on the transmission helps considerably in the shift effort and greatly reduces the notchity feeling. I think I've posted before regarding this mod.

Hi Ranger,

I have spoken to Carczar, and he describes it as "under acceleration, it pops out of gear and winds up in neutral between gears". I haven't driven his car and I haven't ridden in it, so I can only go by what he has told me and the fact that I know he owns and drives many performance cars and has for a long time.

Cheers,

That sounds like the last thread dscription.That guy had a new tranny under warranty.

This transmission on the 06Z is one of the easiest I've had. The Shifter litteraly knows where to go. I realize that after I read the post of Ranger's and how he shifts, that it's the same way I do shift. I suppose he knows more than most. Also, If you are only half-clutching the car while shifting, I have noticed it doesn't go into the gate completely. Try pushing the clutch all the way in.
