Default Anti Venom Mod= No Difference!

Did the mod yesterday. After the install, I took out the C5 and did not notice any improvement. The shifting is still notchy as hell. I'm still hunting gears and 2nd gear always bites me. It has a very small sweetspot. I want to race this car, but 'not feeling comfortable or confident enough to do so.

I used the 2 washers. Go to 3?

2 washers is kind of the max.

Just to clarify, the anti-venom mod only affects the effort to move the shifter forward/backward. It will make zero difference on side-to side shifter movement. Maybe try one washer? (or did you already?)
Anti-venom won't help you with "hunting gears" in my experience, if anything it will hurt it.

What shifter?

What he said.... MGW shifter made a world of difference in the feel of the trans....Anti-venom made it less effort.

It's never gunna shift like a Jaguar. Try changing your trans fluid. I went with Amsoil. It shifts like butter. Chunky butter.

Yup, 'knew that. My 1st-2nd shift is tricky. So is downshiftting 3rd-2nd. It's a B&M shifter. I'll keep it as is for now, and just work with it.

Thanks!

Kinda sounds like your shifting is off kilter. Have you already tried aligning the lower shifter box? If that checks out, it almost sounds like an issue with the 2nd gear synchro.

A mechanic friend told me that too. But no, I have not tried lowering the shifter box. Any detail/instructions would be appreciated.

2nd gear syncho issue sounds expensive to repair.

There are some good videos on Youtube for aligning a stock shifter, like this:
The 1st comment in that video mentions their 2nd gear being difficult, but after aligning it was all better.

The whole center console has to come off to access & align the shifter.

Thanks! But I got a B&M speedshifter. I'll watch the vid anyway.

I just took the C5 out for a spin. I managed to shift 1-2 and 3-2 cleanly, although 2nd gear bit me once out of 7-8 shifts. I learned that I need be more precise and use more muscle regarding 2nd gear. I am still used to shifting all previous Camaros, and like one member said, it's like comparing apple to oranges. There feels like I need to clear 2 dentents before being solid in 2nd. I can feel it in the shifter.

Thank you!

Wasn't sure if the B&M has the provision for factory shifter alignment pin, now I know
So just last night I aligned my lower shifter box since it was removed from the car. Like you I don't have the capability to use the pin. What I do is loosen up the linkage bolt a tad, do my best to center the shifter's shaft vertically (for both fore/aft and left/right), and tighten the linkage bolt to 22 ft-lbs while trying to keep the shifter's shaft vertical. Worked perfectly for me... granted the synchros and fluid in my trans only have 5k miles on them.

Since you said it has a very small sweet spot. Maybe the skip shift solenoid is interfering with the shift to second gear. I know the reverse lockout solenoid causes issues with reverse and causes going into 5th gear issues when it gets sticky. I replaced my solenoid because of this. Most likely the skip shift solenoid is the same stupid design.

Also my aftermarket short shifter sucked when I first got the car. While installing a radio I removed the shifter and found that the box had no grease on the shaft. Greased it up and it was almost normal. Then I did the anti venom mod and it really became easy to shift. Still a little notchy, but if I shift at over 2k rpm it shifts pretty nice.

Thanks for chiming in with some great ideas!

Sounds like the problem is the crappy shifter. Pick up a used C6 shifter, then have TMOD rework the lower box and it will be smooth and easy.

When I bought my car I didn’t know it had a Hurst shifter. Super notchy and while it did have a short throw it was really hard to get into reverse and fifth. My wife didn’t even want to drive it.

At least toss the B&M and put in a stocker…

Your box is almost certainly shot. Send it to me and I'll fix it up, it will be a night and day difference. Then you can play with adding spacers to the detent, you probably won't even want to. After I do the box you also want to replace the factory shifter bushing with mine, it will be, like I said, night and day.

My Hurst is also tough for me to get into 5th, reverse is not as bad but I do have to push, but 5th is tricky to "find".

the only gear I find difficult is 2nd. It's not terrible but definitely need to throw it down intentionally all the way back. I'm going to try re-aligning at some point and of course change fluids. Otherwise I find the stock setup to shift pretty nicely, although a bit long in the tooth.

This is exactly what I am experiencing. I took the C out today and did not grind 2nd. But I did have to slam it all the way down. Even when downshifting 3-2.

If you rev-match with a little throttle blip beforehand, it tends to help, but sometimes I'm too lazy for that. Overall I'd say it's not too bad, I'm still learning the car. But definitely will be doing fluids later this summer or fall.

Yup, getting ready for the strip. Gotta cover everything, then all systems are "go." It's too hot and muggy now. Lose too much horsepower. The DA sucks. I am ready for Fall.
