Default Manual Transmission

Just sold my 2012 GS Vert with manual in anticipation of a C7 in the next year.Is the C7 manual trans less notchy than the C6.

Never had a C6 manual but the C7 feels a bit notchy I guess from 1st to 2nd. All other shifts are seamless and smooth.

It could be just because the 1st to 2nd is more down and toward you rather than straight back which I'm not used to feeling.

Very short throw though.

Love it overall.

This is the 2nd best manual transmission I've owned; 2nd to the Honda S2000 which is probably the best shifting manual transmission ever created. I'm usually quick to jump on short-shifter kits, etc. with my sports car, but I haven't found the need on the C7 thus far.

I don't find notchiness with the 1st to 2nd shift. I had a 2009 BMW 535 which I had to pay attention to the 1 to 2 shift due to its notichiness and a 2005 G35 which had similar 1 to 2 shift notchiness. The C7 is a pleasure to shift.

This. I think the M7 works well. Not sure if I'd do an MGW kit or not. The feel of the stock setup is fine and I just don't see shifting any faster or more precise than I can now. Only time I missed a gear was the 2nd time I gave it hell and got hung up on the 2-3. Been playing with no lift shifting and nail it every time now. I dig driving this car. Put it in rev match mode and it makes everyone who drives it look good. GF doesn't lurch gears and makes a much better designated driver in the C7.

The car will also Rev Match on up shift if you're shifting too casual/slow.

Don't recall my C6 feeling notchy. The C7 if fine. The 1st to 2nd shift when the trans is cold is a bit stiff. I just pull back with a more force. Once warmed up, it's fine. I love rev match. Always heeled toed the C6 and my other two Vettes ( and other cars and trucks) and was pretty good at higher rpm shifts but part throttle shifts in normal driving were often not a perfect match. Tough to modulate the throttle perfectly when just downshifting when making a turn for example. Rev match does it perfectly every time!
With three overdrives it's foolish IMO to downshift fron 7th coming off a highway thru 6th and 5th, just go directly to 4th which is 1:1. Rev match makes that easy and smooth. The spring loading also makes that easy as the 3rd 4th gate is where it will go if no side force is applied.
I read early on that a practice I had used when skipping gears should not be used, it confuses the computer. You can not put the shifter into a gear you do not intend to engage the clutch. The Hall sensors they use anticipate the next gear and it gets confused. No need to spool up the gear clusters the trans has triple syncros, some carbon lined. They do the job fine without your help. There was a comment made that doing that can cause damage as well. Not sure why.

The Hall effect sensors do not "anticipate" the next gear, they tell the computer which gear the car is in and display it on the dash. The sensor simply detects the position of the shifter.
IF you skip a gear, it detects which gear the transmission is in and matches revs faster than you can release the clutch...

Meant to add that I did have problems getting my C5 Z06 into 1st gear and shifting sometimes....That problem has been eliminated on the 7 speed.. It never fails to go into gear easily the first time... I put in an aftermarket Hurst shifter just because I like the retro look..

I never had a C6 either, but my C7's manual is much better than my old G35. It feels notchier than my old car yet smoother in every aspect. My G35 had a very wobbly stick and it would sometimes pop out of gear even though you know you shifted into one. I was surprised how refined and how easy it was to drive compared to a luxury styled car. I sometimes have a hard time with 5th and 7th gear. It's still very strange having that many gears and I just tend to miss one or the other sometimes when changing in between them.

I have to agree that the no lift shift is very fun. It makes it sound like a race car when you're flying through the gears.

Yes, that has surprised me a few times. As for notchy, it was more so when new, but with 5000 mile it's much better. I still have occasional problems shifting to 5th and 6th if I'm not paying attention. The centering is pretty strong so I hit 3rd and 4th instead. That's just laziness on my part, not really the shifters fault.

A bit of semantics but I agree the Hall sensors don't think they just report to one of the CPU's. The issue I had was what I had often done with previous standard shift cars when skipping gears on a downshift. With the clutch depressed I would put the shift lever into the skipped gear then the gear I was going into before engaging the clutch. That confused the CPU not the Hall sensor but in any case the "system" didn't know what I was trying to do.
This is my third 7 speed! Granted the others were a bit different. My '79 Dodge a Colt, '84 Dodge Colt Turbo and my '88 Vette with a Doug Nash trans that had an electricically actived overdrive behind the 4 speed had 7 speeds. The Doug Nash could be used in all but 1st making 7 speeds. The Colts had a two stick shifter for the two speed "overdrive" than could be used in any of the 4 gears. However two of combos were the same ratio making 7 not 8 speeds. Would split shift both types from time to time for fun!

I went from a 2008 C6 manual to a 2015 manual and have found the C7 manual to be smoother, especially when it is cold, which was a problem with the C6.

just go drive one...

First is tougher to get in...rest of gears it's much smoother than C6

Clutch is a bit more "springy" if there is such a word

The trans is fine, the stock shifter a little mushy/not precise. I put the MGW shifter in and it is awesome now, best $360 ever spent. I have big hands so I use basically my index and pointer finger along with my thumb, its very easy, smooth and precise.

Am I only one who misses shifts in this car or only one who will admit it? I've had about 50 stick shift cars but I'm getting hung up between 4-7, wanting to go to 5th, and going from 7th to 6th, I hit 4th.

The springs that bring the shifter back to center seem to be really tight. (Not sure if that's an accurate technical description but it feels like that.) I had to get used to "guiding" the shifter instead of letting it flow.

Had a 2012 GS vert too and have a '15 Z51 manual now. The shifter in the C7 seems to be much better to me. Took a little getting used to (maybe 200 miles) but with any new car you have to "learn" a bit.

Maybe just sit in your driveway,going thru the gears,downshifting also.
Kind of get the feel form one to the other.Thats what I did at the dealer.
Again after I got it home.7 speeds is a lot.Just need to practice.
