The automatic transmission can be described by the following

The automatic transmission can be described by the following: (choose the best answers) Choose all that are correct a. Consists of at least a torque converter and an automatic gearbox b. torque converter consists of at least a turbine, impeller, and a stator c. gear ratios are sized based on matching engine capacity factor to transmission d. Can achieve increased efficiency by allowing the stator to rotate freely in both directions

Solution

Solution :

The correct options which describe the automatic transmission OPTION B and OPTION C.

No automatic transmission need not consist of a torque convertor as the DUAL clutches exist today which are fully automatic and they dont consist of a torque convertor.

Yeah torque convertor should consist of Impeller, turbine adn a stator without any of them there is no meaning for Torque convertor.

Yeah gear ratios are based of matching engine capacity.

The efficiency will decreases if stator is allowed to rotate in both direction.
