The clutch brake is intendedto only be used while at a stop. Care must be taken to not activate the clutch brakewhile shifting between gears. This could lead to excessive grinding or a blocked ormissed shift.

Skip Shift

Currently, the Cadillac CTS-V, Pontiac GTO, Chevrolet Corvette and Camaro SS (othermodels may follow) equipped with the 6-speed manual transmission have a feature referredto as a "skip-shift.” This feature only allows a shift from 1st to 4th gear when theindicator lamp is illuminated on the dash. Dealers cannot disable this feature asit was established to help meet fuel economy standards. The conditions for this featureare: enginecoolant at normal operating temperature, vehicle speed of 24-31-km/h (15-19-mph),21% or less throttle being used (refer to Service Information or the Owner Manualfor more details.)

GM bulletins are intended for use by professional technicians,NOT a "do-it-yourselfer".  They are written to inform thesetechnicians of conditions that may occur on some vehicles, or toprovide information that could assist in the proper service of avehicle.  Properly trained technicians have the equipment,tools, safety instructions, and know-how to do a job properly andsafely.  If a condition is described, DO NOT assume that thebulletin applies to your vehicle, or that your vehicle will havethat condition.  See your GM dealer for information on whetheryour vehicle may benefit from the information.
