TODAY'S TECHNICIAN: AUTOMATIC TRANSMISSIONS AND TRANSAXLES, 5E is a Classroom Manual and Shop Manual set that has been completely updated to help readers keep pace with industry trends and the needs of automotive education programs across the country. This book's technician-oriented focus will help readers master all of the design, construction, troubleshooting techniques, and service procedures required for them to enter the workplace. The Classroom Manual begins with an introduction to drive train basics and the Shop Manual begins with an introduction to safety. This is followed by a review of directly relevant electricity/electronics principles, plus more opportunities for readers to gain practice in using scanners and oscilloscopes to develop critical thinking skills, diagnose problems, and make effective repairs. TODAY'S TECHNICIAN: AUTOMATIC TRANSMISSIONS AND TRANSAXLES, 5E also includes an introduction to continuously variable transmissions (CVT), up-to-the-minute coverage of drivelines for front-wheel drive (FWD) and four-wheel drive (4WD) vehicles, as well as the latest information on today's high-tech electronic controls and automatic shifting devices.

Features and Benefits

  • Includes new topics on hybrid vehicle transmission designs, the Lepelletier gear setup, power split units, and various continuously variable transmission (CVT) designs and all new content on electronic control systems.
  • Contains superior topic coverage that provides your students with the most complete and up-to-date information on automatic transmission theory, diagnosis, and repair available in a single source.
  • Contains improved illustrations and step-by-step photo sequences that include all major automatic transmission repair procedures and promote professional work practices.
  • Focuses attention on the performance of common service procedures through the use of Job Sheets in the Shop Manual.
  • Includes a comprehensive Spanish/English glossary, plus the addition of J11930 terminology to help your student master terms, as well as an ASE practice exam.
