"Why See a Marriage Counselor? Get a Select Shift." Ford Motor Company Advertising Proof, 1967

The automatic transmission combined a fluid coupling with a planetary gearset to eliminate the driver's need to push a clutch pedal and shift gears. The convenience was offset somewhat by lower fuel economy due to slippage in the fluid coupling, and reduced control while driving downhill or in slick conditions. Ford's "Select Shift" transmission compromised between automatic and manual.
