Figure 100–1 A cross-sectional view of a Chrysler Power Flight 2-speed automatic transmission used in the 1950s. Most of the heat generated in an automatic transmission is created in the torque converter. This air-cooled unit has a vent to allow hot air to escape. Continued
The outlet side of the impeller vanes accelerates the fluid as it leaves the impeller to increase torque transfer to the turbine. See Figure 100–2. The inlet side of the turbine vanes absorb shock and limit power loss that occurs when flow between the impeller and turbine suddenly changes. The curve of the stator vanes is opposite to the curve of the impeller and turbine vanes. See Figure 100–3. Since the stator is located between the impeller and turbine, it adds to the original impeller flow and multiplies the force delivered to the turbine. See Figure 100–4. Continued
