Eight-speed automatic transmission

Eight-speed automatic transmission has five torque-transmitting clutches that are engageable to the gears, carriers and transmission housing in combinations of three to establish eight forward speed ratios and one reverse speed ratio

8-Speed Transmission With Two Fixed Interconnections

8-speed transmissions

Multi-speed transmission i.e. planetary transmission, for use in e.g. powertrain, has torque-transmitting devices engaged in combinations of two to establish eight forward speed ratios and one reverse speed ratio between input and output

Multi-speed transmission i.e. planetary transmission, for passenger vehicle e.g. car, has five torque-transmitting devices engaged to establish eight forward speed ratios and reverse speed ratio between input member and output member

8-Speed Transmission With Two Fixed Interconnections and One Grounded Member

Transmission i.e. eight speed automatic transmission, has torque transmitting devices that are selectively engaged in combinations of three to establish eight forward speed ratios and reverse speed ratio

Transmission e.g. eight speed transmission, has five torque-transmitting mechanisms selectively engaged in combinations of three to establish eight forward speed ratios and reverse speed ratio between input and output
