I hate the skip shift. Can I over ride it?

There was confusion in October 2013 as there were CEL trips with some Eliminators for a C7. (Turned out they were defective!) I finally bought one after talking with the company that made them, it measured the same, 2.18 Kohm. That is in the plug going to the wire harness. You're paying for the two plugs (which are different in the C7 vs C6) and a resistor known to work and not burn out! Mine lasted 3 1/2 years in my 2014 C7 and was working fine when I sold the car. See they are being sold for $11! Can't beat that for a protected resistor with the correct 2 plugs!
Both it and the one I bought for the Grand Sport were one piece with two wires connecting the plugs. Makes it easier to use a wire tie to hold it close to the trans and avoid contact with the exhaust pipe.
The side that plugs into the solenoid read very low resistance. But that doesn't mean anything as the plug going to the solenoid is only being used to keep the connector on the transmission clean! Therefore the wires could be a dead short and the unpowered solenoid would not care! The plugs are NOT connected internally. That is why there was a 25 ohm measurement! The only resistance that matters is that connected to the cars harness.
Made a schematic to show what is happening:

All these posts about well, just rev it higher in 1st miss the point. There are times when that just doesn't work like making a slow right turn behind slow traffic. I instinctively shift to 2nd mid turn and then get lugged down in 4th. I know, I could consciously try not to shift but I still mostly do. I don't have an eliminator yet so it bites me once in awhile like that but never on a straight take off.
I get caught by it every now and then, so, when I feel the shifter heading for 4th I leave the clutch in, let the shifter just touch Gate 4, shove the shifter forward until it just touches Gate 3 and then pull back into Gate 2. It only takes a fraction of a second (about as fast as you can move your hand through the motions while sitting in the house) and the car barely slows during the process. That fraction of a second means nothing since you aren't going anywhere fast anyways with your front bumper 4 ft from the rear bumper of the car in front of you going 17 mph.

I'll try this. My guy said to double clutch, but a pause sounds like it works too. Folks are right, no big deal. Thanks!

Hmm, why put up with needing a tricky clutch shift movement, double clutching and just waiting until it locks you out even once! For ~$11 and a few minutes of work it will never happen! It is easily reversed if for whatever reason you feel the need!
Perhaps it's a challenge, but you're just defeating something GM used to get a few more tenths for their corporate average MPG when conducting the Federally mandated driving cycle! I know none of you are short shifting to the next gear when it will bring the rpms to ~1000 as it defines in the Owner's Manual to achieve max mpg! I don't look at the dash to see if my "shift light" comes on and doubt it is very often but it's a none issue with the "Eliminator Installed!"
As mentioned, in my C6 it never happened in 6 years as had the "Eliminator" installed. In my 2014 C7 it happened once in bumper to bumper traffic before I installed the Eliminator! It will never happen in my Grand Sport as I installed the "Skip Shift Eliminator" with ~30 miles on the car as it was jacked up while installing low dust ceramic brake pads!
TO EACH THEIR OWN!

Are you unaware of federal regulations requiring that manufacturers meet a corporate average mpg target number for all models produced by that manufacturer? Are you aware that the target numbers move increasingly higher over time? Did you know that CAGS allowed both the C6 and C7 to avoid the Federal Gas Guzzler Tax? Do you really think manufacturers designed and implemented things like CAGS and Start/Stop systems because they wanted to?
The 15-19 mph window for CAGS is actually incredibly clever, because it satisfied federal regulators, and the engineers knew full well that the vast majority of customers driving Corvettes would never see it.

And I can push a button to disable Start/Stop, so out the window goes the federal regulations to meet the corporate mpg target.
As dumb as dumb gets.

It's going to be an issue for me because I'm teaching my son how to drive a stick in a very big parking lot (I know, don't teach him on a Z. We'll go slow) and explaining the h pattern while the car is blocking him out of second is a problem. Can't really go 20mph to avoid the block. I don't want to teach him on the road until he gets the process down.

Well the hardest part of a stick is simply getting the car moving. I taught 2 kids to drive stick and did not let them out to the road till they got good at that.
Same deal for reverse. Reverse is a bit easier to learn clutch, as the lower reverse gear is more forgiving. Your son will probably be a bit tentative in shifting gears so a slow shift will not engage the skipper.
No I did not teach them with a Vette, but basically a stick is a stick. Kids must have learned something from me as both have class 1 licensees and in fact the older one pulls double bottoms and pulls down a decent salary and is home each night!

Our new Malibu has start/stop and there is no disable button on it.
I think Cadillac started out with a button, but may have removed it in later models.
The government will probably make the manufacturers remove all bypass buttons eventually.
As has been pointed out, if you pause before going to second, the car should shift.

Not on a new Chevy... The Chevy engineers say that if the driver needs a disable switch, then we did not design it right..

The Viper used the same Tremic 7 speed as the C7 and had "Skip Shift." Apparently an "Eliminator" trips codes. GM would just have to add a position sensor on the blocking solenoid to have that occur! Thank goodness many folks object to spending ~$11 and a short time it takes to install and GM did add one to Vettes! Since manuals are only 23% of the Vettes sold and apparently only a small percentage of us install one, it's a none issue!
Perhaps the small percentage of standard shifts is why we also avoid forced 8 to 4 cylinder, except in ECO Mode. Glad for that!

Agree, we have start/stop on all our other vehicles, and it's a non-issue. I always leave it on, and the engine is re-started before I can move my right foot from brake to throttle.

"014-2018 C7 Corvette Stingray Skip Shift Eliminator
Also called CAGS Defeat
Do you hate the 1-4 skip shift installed on the C7 Manual Transmission? This little device will eliminate that annoying issue.
I know that some ads for C7 bypass actually say for use on C7 only, so I was not sure if the resistance was different. The ones I have seen that have a separate cap and resistor plug do have a lower resistance value.
'"Our Corvette skip shift kit will allow you to disable the Computer Aided Gear Selection (CAGS) feature of your C7 Corvette's 7-speed gearbox. This kit comes with the correct connectors, plugs and seals to protect your wiring harness and CAGS solenoid to allow you to re-connect the harness for full CAGS function, if you so desire. This kit is designed for use a C7 Corvette only. Will not fit C5 or C6 Corvette. No permanent modifications are required to install this product."

As I recall the connector plug is different.

I have noticed that some connectors look the same outside, but have an extra partition in the female connector..
I have some extra connectors, but just need to know the correct resistor to use for the C7.

There are three M7 transmissions used in the C7.
If you have a Z51/GS than you would have to go to 2560 RPM to get above the CAGS(20 MPH). Why go that high? It's not needed.
If you have a base Stingray then you would have to go to 2300 RPM to et above the CAGS(20 MPH).
If you have a Z06 then you would have to go to 1975 RPM to get above the CAGS(20 MPH).

17 MPH is the recommended shift speed for the best gas mileage and it is a forced shift from first to fourth gear. That is not the speed that one has to reach in order to shift directly from first to second gear.

He did great yesterday and today. I taught him in a huge parking lot and once he figured out the clutch, it was easy for him. He and I put at least a hundred miles on it over the weekend, just tooling around town. It was tough for him to keep it below the break in RPM's, lol.
You're right, reverse he got right away. The skip wasn't too much of an issue for him for the reason you stated (in the lot). Once we were on the road, he never shifted into second until he was going about 25 or so and yes he was slow to shift so it was moot.
I guess I drive like a grampa. I'm old enough to be...
Thanks!
