• This class and manual will introduce you to the Powershift Transaxle. When you have completed the class and passed the test, you will know how the components of a typical Powershift Transaxle work and how to troubleshoot them. The power train consists of three units: torque converter, transmission, and drive axle (also called “power axle” or “Transaxle”).
• The power train receives energy from the engine and converts it through the torque converter and transmission into energy to power the drive axle and wheels. A hydraulic system plays a vital role in the functioning of the torque converter, transmission, and drive axle. In Clark equipment, the converter, transmission and hydraulic system function as a unit called the Powershift Transmission.
• In smaller units, the drive axle is considered a part of the Powershift Transmission and the whole unit is referred to as the Powershift Transaxle. Note To avoid confusion, the terms “Powershift Transaxle” or “Powershift Transmission” will always refer to the whole unit, while the term “transmission” will refer only to the part of the Powershift Transaxle that contains the gears and clutches.
• Because the converters, transmissions, hydraulic systems and drive axles on different models will vary, this class will discuss a typical Powershift Transaxle. Other classes will cover how to troubleshoot and rebuild specific transmissions and transaxles in greater detail.
• Whenever you are working on a transmission or transaxle, always consult the unit’s appropriate service manual. The first five sections of this manual will show you how the components of the Powershift Transaxle work.
• You will also be introduced to some problems that might occw· if these components malfunction. The sixth section will teach you the basic approach to troubleshooting the Powershift Transaxle. A reference guide is included at the end of this book to assist you in troubleshooting.
