The AF23/33-5 is a fully-automatic, five speed, electrically controlled, front-wheel drive transmission. This transmission is currently used by many different vehicle manufacturers, among them are; GM, Infiniti, Nissan, Saab, Saturn, Suzuki, and Volvo. In the GM, Saturn and Suzuki vehicles, the transmission is known as the AF23/33-5. In Saab vehicles it’s designated FA 57. Nissan and Infiniti call it the RE5F22A, and in a Volvo it’s known as the AW55-50/51SN. This transmission contains three planetary gear sets, three driving friction elements, five holding friction elements (one of which is a servo applied band), two sprags, and a torque converter, which contains a clutch assembly for increased fuel efficiency. The three planetary gear sets provide five forward speeds and one reverse speed. Gear ratio change is fully automatic and controlled through the Transmission Control Module (TCM). The TCM monitors and receives inputs from various electronic sensors, then uses the information to control shift timing, clutch apply control, line pressure control, and torque converter clutch application.
