Does the C7 manual transmission require after market installation to bypass the 1-4 shift

 

Yep, a ~$25 mod well worth the cost IMO.

I consider it a safety issue as well as an avoidance of an occasional annoyance. I'll explain: Had CAGS (Computer Aided Gear Selector) eliminator on my C6 for 5 years so never was bothered by the issue. When I got my September 2013 built C7 the CAGS defeat suppliers were trying to define the resistance level needed for the device. I was not initially bothered by skip shift because I shift above ~2000 rpm out of 1st gear. However I got caught in bumper to bumper traffic, moved forward and tried to shift at a lower rpm. Thought perhaps I was not shifting correctly since it would not go into second. Took several seconds until I realized what was happening. By that time the car slowed significantly leaving a large gap to the next car in line.

If when I moved forward and the person behind me followed and had a beep on their cell phone then just looked down to see who sent the message they could have been in my rear! My biggest concern driving today is distracted drivers. Have never had an accident with another car in over 45 years of driving (looking for wood) but watching folks text and talk on the phone when driving has me very concerned. Unfortunately for many it has become a conditioned response they can't help themselves! Just takes a second at the wrong time to have that happened.

Bought and installed a CAGS device right after that occurrence! This is a picture PDF of my install for those new owners who are not familiar with how easy it is: http://netwelding.com/Skip_Shift_Eliminator.pdf




Like Pavlov's Dog, Unfortunately Some Folks Just Have to Look at a Beeping Cell Phone It's a Learned Conditioned Response!

 

I've had the skip shift feature on Manual trannys now in 4 C6's and two C7's and I have no problem shifting. If in engages, I just move the shift towards the 4 position and come back to 2 or even 3. The operation feels seemless to me . It effects my driving habits maybe >1% of the time.

 

No, it's completely unnecessary if you wait until 18 mph to shift out of 1st, which I do 100% of the time. That's under 3K rpm, thus can be done even when cold.

 

Yes, it requires the mod or program it out.

 

I was going to buy a CAGS eliminator based on my experience driving a manual Z28 in the mid 90s. However, after driving my C7, I decided against getting it. The C7 CAGS is a lot less intrusive than I remember the Z28 being. In the rare case I activate CAGS, I either move it back to second after starting to go into fourth or I just move it up to third.

 

I asked for one for a Christmas present, prior to actually owning and driving the car. I drove the car for 10 months without ever installing it, and most of the time just held 1st until I hit 19mph or so in slow traffic prior to shifting. Not really a big deal, but in slow bumper to bumper traffic it does come into play quite often. I don't see how you can say it doesn't, but it is easily avoided.

I was changing my rear differential fluid last week so i decided to install it since I had it just sitting on my workbench in the garage. It is nice to have the ability to go into 2nd without having to get rejected, but if I hadn't got it as a Christmas present(per my request), after driving the car for 10 months I wouldn't order one since I know how to avoid the issue.

 

I doubt anyone experiences more bumper-to-bumper traffic than I do in my daily commute into and out of Washington, DC. My office is right between the Capitol Building and the Washington Monument on the National Mall. I commute in my C7 M7 3-4 days a week and the commute is 60 miles roundtrip.

In slow bumper-to-bumper traffic, I just leave in 1st gear. No CAGS eliminator required, and it certainly isn't a safety issue.

 

Another waste of money, why would you shift into 2nd gear at such a low speed or mph. Message comes on just give it more gas or do not shift.

 

We are a tolerant crowd, us Vette owners.

If having the 1-4 skip shift was a free option would anyone choose it? No. It's an annoyance. So why not remove it? I would love one. Now how do I find someone to have that done to my car.

 

Consider it a gift. Along w/ cylinder deactivation, gearing, etc., it saved you a lot of money by allowing the C7 to escape the federal gas guzzler tax. It also helps GM to keep building high-performance cars while meeting federal CAFE mandates.

 

I find it shifts to 4th at too low a speed and lugs the engine. Whenever i feel it doing this, i go to 3rd. Interestingly enough, had the car i weather mode today and it seemed to want to do a 1-4 much more than normal.
It only happens 2% of the time when i drive and as i say... i just go to 3 which is much better for the engine....

I believe that CAGs is only there for EPA certification and as such it must always default to being on... any skilled stick driver can get good fuel economy by skipping to higher gears but there must be some kind of rule that they must upshit 1-2-3-4 unless the cags move it to the next highest gear.

 

I continually find myself amazed at the trivial things that annoy people What is so objectionable about waiting until 19 mph (just under 3K rpm) to shift out of first? That's not exactly aggressive driving.

I can't imagine why anyone preferring a manual would want to shift so early.

 

Hmm, your bumper to bumper in DC is different then in more rural SC! Thank goodness I only have to face it occasionally! But when I do it's not for long and keeping it in 1st is not logical with the large gaps folks leave so shifting is preferred. Don't envy your situation!

I can't imagine why anyone would not spend ~$25 for a CAGS eliminator and having the fun of the install!

 

What's "not logical" about being in first below 19 mph?

 

I guess I'm lucky as I have no idea about what you are all talking about. I just row through the gears and don't get any messages. Am I driving it too aggressively? Nah!

 

Well, you clearly know what I'm talking about. I don't get the CAGS angst either.

 

Honestly I never have the 1-4 shift problem in my M7. I never, ever, go that slow on the RPM'S or the speed.

 

It was in the C5 and I got used to it, when I did a tune to the C7 it removed it.....doesn't matter to me either way.

 

I get the shift skip constantly when i start driving on a cold engine and am taking it easy, so I bought the eliminator for 15 bucks. Just need to install it.
