C6 Manual Shifter Is Rough
This is my second Z51-- 6 speed and the shifter seems pretty nochy and rough. Is this normal?
Is there a way to make it smooth?
The car already has 1000 miles on it so it is as good as it will get I think. Seems that the other car was smoother.
Thanks.

If it still feels rough, I would take it back to the dealer for inspection. These shifters are smooth when working right; long, but smooth. If you don't mind the higher-effort, a good short-shifter would help; don't know if they are available yet.

not a matter
Not really a matter of miles as much as a matter of shifts. Mine took 2500 miles to smooth out but seems whenever I did city driving and the GW bridge it got smoother faster. I did however replace it recently with a Hurst and after a month of driving the Hurst is beginning to smooth out a bit better. Takes time.

I had the same problem as soon as i got my car, first 400 miles were so bad, i really thought i had a broken car, i really did, after 400 miles it got quite a lot better at about 1100 miles now, it's not too bad, but if i take a drive in a german or japanese high quality car(such as a bmw or infinity) there is a huge difference. the *** and german cars shift so so smoothly, i don't mind if the shifter was designed to be rough; like the old muscle car's if it is not behaving like it should i would like to take it into the shop. i am taking it to supposedly the best corvette shop in ohio to ask the chief machanic drive it and tell me what he thinks. that's the plan some time next week, i will update this thread and let you guys know what he says.

My experience has been that it shifts fine under normal driving conditions or even most performance driving. I have had a number of occasions, though where I have REALLY been getting on it (powershifting) and the trans would not go into gear. I've logged a lot of miles in two C4's with the ZF6 both on the street and track and never had this problem... I would have to say that I am less than 100% satisfied with the manual trans in my C6.

I've been noticing that 3rd is a little "notchy". I'm probably going to swing by my dealer, and let my service writer drive it, just so I can get it "on the record".
Aside from that, it does feel alot tighter, and more difficult to shift, than the "euro cars" I've owned in the past (BMW, Porsche), but all the american made manuals I've driven, never seem to compare to the ***/German models - ease-of-shifting-wise.
Regards,
Rick

With 800 miles on my Z51 6-speed tranny, it is still very stiff getting into second under full throttle...resulting in a few missed shifts (ouch!)
I'm also hoping it smooths out with more miles. My 1969 Plymouth Hemi 4-speed shifted smoother than this!
I may have to try the Purple Max tranny fluid, which for some people have anecdotally improved the shift effort.

I changed out the trans fluid (Redline D4ATF) in my Z06 and that helped. I've been considering doing the same to the C6 but I have less than 1000 miles. The C6 shifter is way better than the stock C5 Z06 shifter w/Redline. Now when I swapped to the Kirban shifter that was a huge improvement. The fluid is a cheap and easy fix and it can't hurt.

The dealer took mine apart for the same problems, put it back together and it still didn't work right. At around 7000 miles they put a new tranny in and guess what........................ it still doesn't work right. Now at 10600 miles, it's going back for more tranny service.
