Default 1to4 Shift light?

OK, I have driven it a few days and wonder what's up with the 1to4 Shift light? Why have a 6 six speed if it's telling me to skip 2nd and 3rd?



Edited:

OK, I found out it's a CAGS deal? And never knew what it meant until I saw some references to the 1to4 light and something about gas mileage.

What a pile of nonsense.....

I think it was to make the car have better MPG. Mines been gone for awhile. You can buy the CAGS shift skip eliminator. Or have it tuned and they can turn it off.

gm's answer for you to save gas! Pain in the *** feature, you can get rid of the shift change but not the light. You can buy a plug-in part to elimate the the shift. Like driving a new car when you elimate this feature.

Pretty freakin simple to avoid too, if you are in 1st gear and traveling under 20mph, don't shift, there is absolutely no need to.

i believe it had a lot to do (at least initially) with the CAFE numbers (corporate average fuel economy) and the general's fight to get "under" the required number. the way i remember hearing (and reading in maclean's book and perhaps even all corvettes are red), GM was able to convince the EPA guys that they could reach the number by forcing the 1-4 shift pattern under certain speed limits to boost the vette city mpg numbers.

The feature has been w/ Corvette since the C4-nothing new here. It's all explained in the owners manual.

Either get the cags bypass or have it programmed out. Programming will also keep the light from coming on. The bypass only keeps the solenoid from engaging the shifter linkage, but the light still comes on. I beleive they change the RPM range to something that can't ever occure and thus it will not come on.
