One option that really sets the Camaro apart from the competition (code for Mustang GT500) is the availability of an automatic transmission. The 6L90 automatic was specifically designed for the ZL1 Camaro. It allows for Second-gear starts while cruising around town and 3port Mode for more aggressive driving. With 3port, the transmission stays in the lower gears longer and adjusts for more aggressive shifts. In full-manual mode, the trans will not upshift, even at fuel cutoff. Notice the NACA-style air ducts that aid in transmission cooling. You can also see the transmission pan’s sump, which comes in handy during high-g turns.
