1-4 skip shift suggestion
Hey all I don't know if this has been discussed before. But why can't GM either make this an option to turn this off or just delete it. I don't know much about engines and transmissions but I do know that this is a pain in the ***.
For example today when im just getting off the line and hit the gas with a little throttle It still had me shift 1-4 and when I shifted in the power was null and I thought I was gonna get rear ended. The car just took forever to get to the power band. Anyway I don't want to mod it with the skip shift eliminator but I am just going to say that I want to suggest GM remove this. I also have not seen much gas improvement with this option.
If I could control this like I can control my NPP then I would be ok with that.

It impacts the EPA rated Fuel Mileage. They'd have to measure it without the 1-4 if it could be disabled by the owner in the menus.

If you care too much about fuel, then I think the corvette shouldn't be on the list to buy. Yes its one of the if not most fuel efficient car on the market, but still the 1-4 is just a PITA. How much really would the fuel mileage even be affected anyway

Why complain about it if you don't want to defeat it? The CAGS defeat module is a) simple, b) cheap, and c) completely reversible. What's your problem with it?

On my c5s and my c6, I needed to disable it and did.
On the c7, it has never made me shift into 4th. Not even once. I've seen the light come on a couple of times, but it's never forced me to shift to 4th. OP, you're saying it forced you to do so?

The C7 manual I saw didn't specify the parameters of CAGS, but assuming it's like the C6, the parameters are so narrow, it's easy to avoid. If you don't want to bypass it with aftermarket methods, you can bypass it by:
1 - Shift to second before 15 mph
2 - Shift to second after 19 mph
3 - Shift directly to 3rd from 1st
4 - Give the car more than 21% throttle
By the way, I've now had 4 cars with CAGS. Not directed to the OP, but many times on this board there have been many threads of "it's dangerous, I could be rear-ended or hit at an intersection". It's hard to imagine a situation where you would be at very light throttle (under 21%) short shifting to second (below 19 mph) but yet be in a situation that you need to move so quickly that you need more than 300 lb-ft of torque available at just over idle or else be in danger.

I don't care about fuel mileage. I was stating why GM can't make it a user controllable setting. I have yet to have a 1-4 shift forced upon me in 7 months of daily driving, much of it in stop-and-go driving.

Sorry I wasn't saying you. I Meant as in a prospective buyer looking for a car that gets good mileage should stay with a prius.

The lack of power. You floor the pedal and it creeps while people are getting anxious behind you. Or the ones that think they can keep up with a vette by pacing the take off and instead of going into 2nd it springs you into 4th and the guy behind you hits you because even tho the pedal is floored your not going anywhere.
To the others the reason I don't want to mess with it because of warranty issue. I don't want to jeopardize my warranty with a modification. I also haven't had the chance to research anything either

I just received my '15 & the installation of the skip shift eliminator was the first thing I did. I drove it to work for the first time today & while I no longer get the 1-4 skip, it's throwing a check engine light. The lady who lives in the rear-view mirror confirms the CEL is coming from a "malfunctioning" skip shift system.
My question is this: Did I bollocks the installation up? Did something change in the '15 to render this unit ( ) incompatible?

The skip shift CAGS has been a standard feature on every GM manual 6&7 speed for the past 25 years now. It's a ruse to increase the EPA gas mileage numbers; and in some cases like the C6Z, avoid the Federal Gas Guzzler tax. Time to get over it. Live with it, adjust your driving technique or disable it like I have on the past three Z cars.

Gas Guzzler tax is not the same thing as CAFE.
