Help Please with C.A.R.S
This is the "skip shift" feature which forces you to shift directly from 1st gear into 4th gear on the manual 6-speed transmissions under certain conditions (by locking you out of 2nd and 3rd gears). This usually occurs at the most inopportune times, such as when trying to make a quick left-turn through a busy intersection. Most of us find this "feature" highly annoying, and disable it by moving that "min coolant temp enable" slider up into the inoperable range.
I always heard that GM created this "feature" to avoid the gas guzzler tax, but it really could get someone killed if the car stalls out at the wrong time.
