The Hydra-matic 4T60-E 4-speed overdrive, electronic transaxle consists two primarily of a five element torque converter: planetary gear sets, various clutches,final drive assembly, differential assembly, and a control valve body. The torque converter houses a pump, turbine, pressure plate which is splined to the turbine, and a stator assembly, serving as afluid coupling, it smoothly transmits power from the engine to transaxle. It also the hydraulically provides additional torque when required. When applied, the pressure plateprovides a mechanical directdrive coupling of the engine to the transaxle. The two planetary gear setsprovide the four forward gear ratios and reverse. Changing of the gear ratios fully automatic and is is accomplished through theuse of various electronicand mechanical requirements. Four multiple disc clutches, two roller clutches, a sprag clutch, and three bands provide the friction elements required to obtain the various ratioswith the planetary gear sets. A hydraulic system (the controlvalve body), pressurized by a vein type pump provides the working pressure needed to operate the friction elements and automatic controls. 341
