In 1955 the automotive industry finally standardized the shift quadrant on all vehicles. From that time forward, all shifters would read from left to right (or front to back) and the order would be: Park, Reverse, and Neutral, followed by the Drive Ranges. This concept of a uniform approach seems fairly simple, but keep in mind that the industry was already more than 50 years old when this happened. As automotive designers invented new concepts or refined previous approaches to mechanical design, standardized naming does not appear to have been very high on their list of priorities. They sometimes named the part as they envisioned its function or they may have reused a name previously associated with a similar design. Mechanics and rebuilders have added to the confusion, identifying and naming parts on their own instead of researching to learn the correct names. It is not difficult to understand why the standardization of names within the automotive industry has taken so long. The torque converter segment of the automobile industry is no exception. As a result, it has suffered from misunderstanding and miscommunication since its infancy.
Last month we traced the origin of the names for the four (4) main components of the torque converter: impeller, stator, turbine, and cover. Unfortunately the problem does not end with these four components. Torque converter rebuilders use many different names when referring to the individual parts that make up these main components.
