You will be locked out and can't shift to second while the light is on unless you have a bypass installed or have the 1-4 tuned out.

Once you are going about 17-18mph, you can shift to 2nd without any problem.

You can do that? I thought second and THIRD are locked out when the skip shift is active.

Right, the skip shift is 1 - 4.

I just shift to 2nd after I hit 20 MPH. No big deal.

It seems many here get worked up over it. I have had it happen twice, and my C7 has 350 Miles on it. I just wasn't paying attention when it happened, now I do.

On the rare occasion the skip shift engages, this is what I do. Or, just wait a few seconds for the car to decelerate and then you can use 2nd. The skip shift window is very narrow, it usually only comes into play in very slow starting situations.

I don't think its possible to damage the trans during the 1-4 unless you are just plain being abusive and force it as hard as you can.

The CAGS is much less intrusive than the C6/5s were. I was all ready to install the bypass like I did on prior models but it just seems to have a much smaller lock-out window. If i do get the lockout I just slip it into 4th and back to second real quick. No problem.

you can do it, try it.....slide it like you're going to 4th then just push it up, 2nd is locked out, not 3rd.

I stand corrected, thank you.

It's just 1 to 4 because of the downward motion.

The stated purpose of CAGS is to improve fuel economy under “normal” driving conditions. In reality it is just there so GM can keep the .gov happy.

The skip shift eliminator is probably the first and only mod I'm planning on my C7. I like the car pretty much as is.

It didn't keep the C6 ZR1 owner from avoiding the gas guzzler tax, but it is there to help improve the car's gas mileage in city driving.

Yep. Skip two lunches in order to have the $20 to purchase the Skip Shift Eliminator, and you will benefit in two ways.

Run up the RPM some and it'll disappear thne shift to 2nd; if you can get the RPMs up that high stay in 1st or shift to 4th then back down. I just raise the RPM faster and can save my money!

Not sure about the C7, but the owner's manual for the C6 (yeah, I actually read it) states very emphatically IN BIG BOLD PRINT that damage can occur if you force the gear shift into 2nd or 3rd while the light is illuminated. At least for the C6, there are very specific conditions that need to be met for the skip-shift solenoid to engage: 1) engine coolant temp must be above 169 deg, and 2) speed must be between 15-19 MPH, and 3) throttle position sensor must be less than 21%. [See section 5-21 in the OM]

It is also true that once you shift from 1st to 4th gear, you can then access either the 2nd or 3rd gear even if you're still in the restricted MPH range. What I typically do when I'm lightly accelerating, rather than fight the RPM forced-shift process, is depress the clutch, slide the gear lever into 4th WITHOUT RE-ENGAGING THE CLUTCH and then go immediately back to 2nd or 3rd and continue on. The alternative is to simply start in 2nd gear or when appropriate, roll the stop in 2nd without going to first. Honestly, I've never really found the feature to be that intrusive during everyday driving.
