6-speed automatic transmission for GS

Standard on GS models, this 6-speed automatic transmission transforms your 2013 Buick Regal from sporty sedan to dynamic sports car. Electronically controlled overdrive provides comfort as you cruise down the road for those longer journeys. Driver Shift Control, which operates by sliding your gear selector to the left, puts this sedan completely under your control, with simple up and down shifting just a "tap" away without the need for a clutch.
