Automatic TransmissionVehicles equipped with an automatic transmission, inaddition to the usual P, R, N and D quadrants feature anM or Manual position. This position is used to accessthe Driver Shift Control functions as outlined below.

Driver Shift ControlCamaro models offer additional driver shift controls inthe form of a (M) Manual position on the floor mountedtransmission shifter and two “paddle” switches on thesteering wheel. While all trim levels and powertrainsoffer these controls, the way they function is differentbased on the way the vehicle is equipped.

6.2L V8, 3.6L V6 (with GW6 3.27 axle)Vehicles equipped with these powertrains feature inaddition to full automatic shifting, a selectable sportand manual mode.To use these modes, place the floor mountedtransmission selector in the “M” position.

Sport Shift Mode Engaged

2713725

• The DIC will display “S.” This indicates SportMode has been selected.

• When you are in the Sport Shift Mode, thevehicle will still shift automatically. Thetransmission may remain in a gear longer thanit would in the normal driving mode based onbraking, throttle input, and vehicle lateralacceleration.

• Tapping either steering wheel paddle controlplaces the transmission in Manual mode.

Important: The driver can return to sport modefrom manual by holding either paddle for more thantwo seconds.

Manual Shift Mode Engaged

2713726

• When going from sport to manual mode, theDIC will display “M” and the selected gear. Atrest if you tap the right paddle M2 will beselected if you touch the left paddle M1 will beselected.

• The vehicle can be commanded to start from0 mph in second gear “M2” for easier startingon low traction surfaces. 6.2L V8 equippedmodels may also be started from 0 mph in thirdgear “M3.”

• Each time a paddle control is activated, thetransmission will shift up or down one gear andindicate the current gear selected in the DIC.The transmission will hold this gear until thedriver taps up or down again, or the vehicleslows to the point that the transmission mustdownshift to avoid bogging the engine.

Shift Denied Message

2713728

• If the driver requests an upshift or downshift thatwould overspeed the engine or cause the engineto bog, a “Shift Denied“ message will bedisplayed.

3.6L V6 (with GW8 2.92 axle)Vehicles equipped with the 3.6L V6 and RPO GW8have paddle shift controls on the steering wheelhowever they function differently than the controls asexplained above.

Transmission Selector Lever in “M” Position

2713724

When the floor mounted transmission selector is placedin the M position, the DIC will immediately indicate“M6.” This indicates that the highest gear thetransmission will be allowed to automatically select is6th gear. This effectively allows full automatic operationto be maintained in case the control is accidentallyengaged.Tapping on the down (-) paddle will result in the highestgear allowable to be reduced by one. (i.e.:M5, M4, etc)

Manual Mode 4th Gear Selected

2713731

Example: Selecting M4 as shown above will result infull-automatic shifting up to 4th gear being the highestallowable gear reached.This system allows the driver to initiate a downshift to alower gear for increased engine braking or pullingpower.Note: The paddle controls on RPO GW8 vehicles arenot designed for sport driving, but are set up toenhance driver control while maintaining fully automaticoperation.

Important: Only first gear starts are available with thissystem. If a gear range is selected that will overspeedthe engine, the shift request will be ignored withoutindication until the vehicle reaches a low enough speedthat the shift may safely be accommodated.
