Hello,

I bought my 01 z06 with a short throw shifter. The previous owner thought it was the MGW. I can’t seem to find a logo, as it’s just a short steel rod with a white ball. Anyways, it feels very notchy and I read somewhere about an anti venom mod. What is that? Or is there a way to adjust the shifter?

 

In stock form, the way that the car shifts almost reminds me of an old school transmission that has no, or bad synchros. You have to pause in neutral and double clutch it to shift to the next gear. On the Corvette, however, there is no need to double clutch. Just pause in neutral before proceeding to the next gear.
The anti venom mod will negate the need for the pause and make the transmission shift in one smooth motion of the shifter.

There is no need to do this on a C-5 manual transmission unless there is a problem with the shifter or transmission.

 

agree I’ve never done that with my 03Z it shifts almost like my previous 2012 ZR1 Tremec 6060

 

I've done this mod to two trans on my 02 Z with zero issues. I even spoke to RPM about doing it to my current trans (stage 6) and they have no issue with it being.

 

I just did the anti venom mod on my stock ‘99 a couple of weeks ago after owning this car for 9 years. I used a single copper washer. It is a small but noticeable difference in shifter notchiness. I am happy with the result.

 

I did mine several months ago and am pleased with the result. Just get one of these and then google anti venom mod for instructions.....not a hard job at all.....If you can't locate one let me know and I'll send you this one.

 

I agree, there shouldn't be a need to do this, but a high proportion of cars left the assembly line with this "charming" little quirk, as it was a very popular discussion topic on this and other forums back in the day. My car has exhibited this problem since day one, when I purchased it new in 2003. The faster that you attempt to shift, the more pronounced the symptom becomes. I changed the transmission fluid and this did not affect the problem, nor did aligning the shifter, nor installing a MGW shifter. Thankfully, adding the spacer addressed the issue and twenty years later, there have thus far been no ill-effects from the mod.

If your car does not exhibit the problem, congrats you are among the lucky few. On the other hand, perhaps the original owner already had the mod performed on your car.

 

Thank you guys!

 

The washer makes the sideways movement easier. So, moving from first over to reverse doesn’t dislocate your wrist.

Little trick before shifting into reverse, just go into any other gear first without letting out the clutch, then grab the reverse hole and it will slip right in.

Had a couple old veteran truck drivers who always ground going into first gear on new trucks. They insisted there was something wrong with the clutch. I climbed into the driver seat, started the engine, double clutched, and the shifter practically fell into first. The moral to the story is to set the transmission up for a gear, a soft gesture usually gets her lubricated and ready.

 

Actually, it only affects the forward / backwards shift, does nothing for side to side

 

Having just gone through my MN6 I will say I'm pretty sure this statement is correct.

Here's what I have to add.

If you have an aftermarket shifter (upper) I would strongly recommend removing it, throwing it fast and far, and replacing it with a stock C6 upper. Also, if there's a "anti-venom" washer between that external detent and the transmission case I would also remove it and make sure to store it in a location where it cannot be recovered (**** can it!).

Mine came with a B&M "ripper" on top of the stock housing. The neutral gate throw was so ridiculously short I once accidentally shifted from 6th to 2nd while burning hot into a 90 degree left sweeping corner and subsequently killed the engine when the PCM saw a massive amount of air passing through the MAF with a closed throttle. The car and I survived, but my underwear didn't fare quite as well.

Long story short, the aftermarket (as well as the owners represented here) has (/have) gotten more than a little carried away with this type of stuff (bolt-on performance and styling mods) for all Corvettes made after '96. Your best bet is to rip what you feel to be questionable out and replace it with the factory hardware. If you're not the first owner, assume everyone who has owned it previously, screwed with things. Mine has had 7 previous owners, and the "joy" I've experienced un-doing previous stupidity has just about poisoned my love for the platform. In a nutshell, stupid is a corvette owner. Don't be an owner, be a mechanic.

 

Actually, it greatly reduced side motion on my shifter.

Neither me nor my wife could get it over to the reverse gate without frustration, with the Hurst shifter, a washer later it moved over with relative ease.

 

I'm not disagreeing with you, simply pointing out that in hindsight the Hurst shifter would be what I would have jettisoned.

The B&M a previous owner had installed in mine had such a ridiculously short neutral gate throw that after having driven the C6 factory shifter for a few weeks I would have to say the B&M was unsafe for anyone to use on public streets. I'm not trying to be pretentious, but sometimes you guys (the aforementioned "you guys" being Corvette enthusiasts in general) take things just a bit too far, and then in an effort to one-up everyone else take it a little further. The result is, well, bordering on stupidity.

I have no idea what a factory C5 shifter feels like, but I would bet that a properly functioning one would be a perfect compromise of performance and comfort so your wife wouldn't feel like she was trying to drive a wood chipper that had an 8" vise-grip for a shifter. Not casting any stones, I'm in the same boat with making the car more spouse-friendly.

 

Then you will appreciate that shortly thereafter I tossed the Hurst shifter 👍. While the venom mod improved the situation, it didn’t resolve it sufficiently. So, wisely, I took it farther and acquired an extra lower box and a used C6 shifter. I sent the extra box to TMOD for their rebuild and setup, then matched that up with the C6 shifter. Shifts like butter. I actually sold the Hurst on the forum. Hope they enjoy it…

When I bought the car a few years ago, I didn’t know it had an aftermarket shifter, only that it shifted like “a wood chipper that had an 8" vise-grip”. I only learned it had the Hurst when I took it apart to install the TMOD box. What a piece of junk that was. Still, many of the members seem to enjoy the short throw shifters, even though they require more effort. I prefer a more sophisticated, lol, touring feel.

 

OR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!! Get an automatic.......................problem solved.

 

Or you you could just get a Tesla and let it drive you. I'm sure there are Telsa owners forums where they make fun of those of us who still prefer to participate in the driving experience.

 

What is a C6 upper? This is what’s currently in the car, but I can’t see a logo or anything.

 

The C6 upper I was referring to is the OEM upper shifter components the 6th gen (aka C6) Corvettes came with standard. In a shorter sentence, the factory C6 shifter (the lower box was identical to the C5).

I'm not an expert on the aftermarket stuff, but I think that black aluminum piece that offsets the shift lever towards the driver was part of the MGW shifter package. But I could be completely mistaken. I've seen it before, but there were probably a dozen different aftermarket shifter offerings available over the years.

 

I sold a 2006 Miata to get the 2000 Vette, shifting the Vette will never feel great after that.
Mazda smooth as glass. But the Vette is a little faster..
