Default 1-4 Shift

Guys with manuals will understand.
Is there a way I can turn this thing off? It is annoying.

Here's a guy with a manual who doesn't understand. You'll only see it if you shift between 16 and 19 mph. If you are really into granny shifting, then do it before 16 mph. I never see it because I see no reason to shift before 2500 rpm.

However, there are others like you, with similar driving habits, who are bothered by it. You can buy a device that plugs into the transmission that eliminates it, but the vast majority of us think it's totally unnecessary.

It's there to help the car meet a certain federal fuel economy standard, and you should thank them because you didn't have to pay the "gas guzzler tax."

Pick up a skip shift eliminator, that'll get rid of it.

On the C6, you could just pull the fuse(put in a smart fuse) problem fixed for most but not all. I don't know how that translates to the C7.

I'm with Foosh, however, just run the engine like it was designed to be run and it never show(ed) up (this truism hasn't changed with the gen). Even in traffic, I never had a problem after the first few encounters with the dreaded 1-4 issue.

What RPMs does that correspond to?

Roughly between 2300-2500. However, you can shift before 16 mph and never see it.

Yep, installed on my C6, 2014 Z51 and this week the day after I got my new Grand Sport installed one. I had my car jacked up to install ceramic brakes so putting in the $20 part was very easy! It is a very simple device. It is a plug that fits a matching one on the harness plug from the skip shift solenoid wires. It contains the proper resistor to make the computer think it activated the blocking pin solenoid!

It doesn't happen often but if in bumper to bumper traffic it may depending on when you shift. Easily solved for $20. Search, many vendors sell. It's called a CAGS Eliminator.

This is a PDF of my 2014 install, it is the same on my Grand Sport: http://netwelding.com/Skip_shift_Eliminator.pdf

Note I added some insulation to keep the plug from being heated by the exhaust. The Grand Sport has insulation you can use.

Get the GAGS eliminator for $25.00. Have to say in the 2 years plus of driving my 2015 I have never encountered the 1-4 forced shift. On my 2008 I saw it a couple of times just gave it a bit more gas and then shifted. In any case my driving habits are obviously different from yours just get the plug.

If you accidentally shift while in the Skip Shift range you can double clutch to get into 2nd.

With mine, all you need relax the gear lever to the spring-loaded neutral position and the skip-shift will be deactivated. (16 ZO6.) A question: is there any downside at to installing the eliminator? Battery drain, codes,etc.?

You're absolutely right, it only blocks you once, then is deactivated, so just pull immediately back into second.

There's no downside to the CAGs eliminator, it's just completely unnecessary, unless your driving habits are so programmed that you can't break the habit of 1-2 shifting at low rpms in that very tiny window.

I've been a manual person all my life, and I've always revved to at least 3K before the 1-2 shift in everything. In fact in smaller displacement, lower torque engines, that's almost a necessity. That's the way I'm programmed, and it's also more fun to drive that way.

I am the same way. Have never noticed the skip shift once in my C7. My other car is a 2015 Honda Fit with a manual gearbox and the redline starts at 6800rpm. I pretty much live in the 3-6k rpm range with that car. You just get used to it and the car is much much re responsive and fun to drive.

I spent the $20 for the CAGS eliminator so I could be in charge of when/how I shift from 1st to 2nd gear 100% of the time, and not when the computer thinks I should.

No need to make a special effort to watch the RPM's/speed etc to decide when to shift, with the 1X4 shift disabled. There is no point in taking a 460-470 lb-ft engine to 3,000 RPM's when driving in heavy traffic/slow speeds. Especially in a shopping mall parking lot.

No need watch speed or rpm here either. It's just pure instinct. No need to shift out of 1st in a shopping mall parking lot or in heavy slow traffic. I'm also in charge of when I want to shift 100% of the time without an eliminator.

Moreover, one has no business driving more than 10-15 mph in a parking lot, so CAGs would be completely irrelevant.

Lastly, the narrow 1-4 CAGs zone is not "when the computer thinks" one should shift. It's the range where GM engineers found they could wring out extra mpg, in order to "fool" the EPA fuel economy certification test into higher efficiency ratings than the car would normally get.

It bothered me a little at first but I have learned how to avoid it. Now it's a non issue for me.
