There are literally hundreds of thread on the tranny woes of C5s and C5Zs. The toll of missed shifts, often brought on by pedal woes triggered by poorly maintained clutch fluid.
If you are interested reading up on tranny issues, a search of the C5Z archives will give you plenty of material.
My point was that if it take two hands to move the shifter, one cause is a trashed tranny; the other is shifter cradle problem. Neither one is intermittent. The context of the issues in this thread were max acceleration runs, rather than casual driving, at least that's the way I read it.

Most people look at things from all angles and at the very least give others the slightest benefit of the doubt. You my friend are One Way all the way..
My brakes are low, what do I do? "Change your clutch fluid and it will a be fine" or "practice my shifting drills and that will cure it".
Ok bro.

In making fast reliable shifts in a manual tranny Corvette there are five* separate elements:
Clutch-in
Throttle-up
Gear-change (four different ones for racing)
Clutch-out
Throttle-down
[* Note: those who powershift 100% of the time can eliminate the two throttle step; they also will likely become conversant with tranny woes.]
Those movements must be done precisely and in the proper sequence.
If this sequence is repeated over and over, it is embedded into muscle memory. There, it is retrieved during a max acceleration run and executed automatically. This allows the driver to better focus on other tasks, such as shift points. It also essentially eliminates missed shifts.
I submits that drills are a routine part of all sports. Anyone who doubts that might, for example, want to walk into a gym where boxers train. Shadow box. Light bag. Speed bag. Heavy bag. Punch mitts. Sparring. All of this and more, over and over and over, instilling proper movements and fast, automatic reactions. This is all before the first serious blows are ever thrown in a match.
Perhaps, shifting practice with the motor off isn't for everyone. But it's purpose is fundamentally sound and deeply rooted in traditional training methods of all sports.
Of course, we all know folks who hate to practice anything. They only want to play in the game. Most of us remember those guys from high school, college, or club sports. They usually performed below their potential...because they lacked the discipline to train.

After doing a few track rentals and making 15-20+ passes some days, I can say (with experience) that your clutch fluid maintenance, launching techniques and other posts have been extremely helpful.

I ran the 01 for the first time last night. Made two passes. One was a 12.39 and the second a 12.41. First pass was a 2.1 sixty foot (3K launch) and the second was a 2.2 (2K launch). I don't think I did too bad for the first time to ever let this clutch out faster than something from a stoplight, much less shift quickly. While the 60's sucked big, I'm ok with it. Whoever had this car before me put rocks on the wheels instead of tires. It's like ice off the line. Track prep was questionable, too. Temps were in the 90s and humidity was over 80%. Not sure on DA. Did not powershift or speed shift as clutch pedal is sticky.
Never practiced on the shifting treadmill. I'll go out again when it cools off. I'll see if I can get on the drag radial/intake list. I'm not wasting my time with these cheap *** tires anymore, lol.
