Transmission problem...
Had a few days of warm weather and finally get to get it out and get on it a little. I have a track day coming up at mid Ohio on the 13th-14th and wanted to practice banging gears seeing how i haven't had much seat time after break in (only 1800 mile on it) Since day one of owning this car I have felt that when shifting fast its hard to to go from 2nd to 3rd.(seems like I always hit the gate area between 1st and 2nd). Also Sometimes It would go in second kinda hard. (like notchy) Well today it started grinding when shifting in to 5th. With the track day coming up I think i may just run it like this and have the dealer look at it after....
but what do you guys all think. Anyone else have any of these problems? Also have a note worthy clunk when you transition from on to off gas or off to on gas at low speeds in first or second.

dealer called today stated g/m is shipping them a hole new trans. G/m wants mine back in one piece to find out what failed. They didn't even want the dealer to open it up and look.

I've had the same trouble with third at high rpms. Ground the gears a couple times because it wouldn't go in and I was off the clutch too fast. Let us know of you hear anything back...I'm interested, but not sure I want a tranny replaced.

at low RPM's (under 1500 RPM) This has occurred at least 25 times and the car only has 1000 easy miles on it. I'm gonna have the dearler adjust the shift linkage when I hit the 1500 mile break in period. |

I use to have all these same problems on my SS, I had to teach myself not to try and force the gears. Go easy with the shifts, and they will go in like butter. These trans are notchy, but that's just the way they are.

I forget which one but one of the mags that did a review on the ZL-1 commented on a similar experience with trouble shifting vigoriously so apparently its not an isolated incident and something in there could use a bit of improvment. Hopefully the aftermarket will address it in the near future. Good luck with the new trans and on the track

does anyone know is their a proper way to use the no lift shift when drag racing? I mean i would just clutch at 6000-6200rpm grab the next gear with out lifting the gas and drop the clutch. Is this wrong?? i tried it in all the PTM settings. Seemed that traction control would interfear in the lower settings. I found it seemed to work best with all nannies turned off. But when trying to do this seemed to cause me to most missed gears. Long story short I was more consistent with out it. (no missed gears)
