When did cars have push button transmission

## The Evolution of Car Transmissions: From Manual to Push Button

Introduction

The transmission is a vital component of any vehicle, as it allows the engine to transfer power to the wheels. Over the years, transmissions have evolved significantly, from the early manual transmissions to the advanced automatic transmissions we have today. One of the most significant developments in transmission technology was the introduction of the push button transmission.

What is a Push Button Transmission?

A push button transmission is a type of automatic transmission that uses electronic buttons instead of a gear selector lever to shift gears. The driver simply presses a button to shift into the desired gear, making the driving experience more user-friendly and convenient.

History of Push Button Transmissions

The first push button transmission was introduced in 1955 by the Chrysler Corporation. The transmission was called the PowerFlite and was available on the Chrysler 300 and Imperial models. The PowerFlite was a three-speed transmission that used push buttons located on the dashboard to shift gears.

Other automakers followed suit in the 1960s and 1970s, introducing their own versions of push button transmissions. Some of the most notable examples include the Ford Cruise-O-Matic, the General Motors Hydra-Matic, and the Borg-Warner Torqueflite.

Advantages of Push Button Transmissions

Push button transmissions offer several advantages over traditional gear selector levers. These advantages include:

Ease of use: Push button transmissions are much easier to use than gear selector levers, especially for inexperienced drivers. The simple push button design makes it easy to shift gears, even in difficult driving conditions.
Convenience: Push button transmissions are also more convenient than gear selector levers. The driver can simply press a button to shift gears, without having to worry about moving a lever. This can be especially beneficial in stop-and-go traffic or when parallel parking.
Safety: Push button transmissions can also improve safety. By eliminating the need for a gear selector lever, the driver can keep both hands on the steering wheel at all times. This reduces the risk of distraction and allows the driver to focus on the road ahead.

Disadvantages of Push Button Transmissions

Push button transmissions also have some disadvantages, including:

Cost: Push button transmissions are generally more expensive than traditional gear selector levers. This is because they require more complex electronics and components.
Reliability: Push button transmissions can be less reliable than traditional gear selector levers. The electronic components can be susceptible to failure, which can lead to costly repairs.
Lack of driver feedback: Push button transmissions do not provide the same level of driver feedback as traditional gear selector levers. This can make it difficult for the driver to feel the car’s performance and can lead to a less engaging driving experience.

Current Use of Push Button Transmissions

Push button transmissions are still used in some vehicles today, although they are not as common as they once were. Some of the most notable examples of vehicles that use push button transmissions include the Chrysler Pacifica, the Jeep Grand Cherokee, and the Fiat 500.

Future of Push Button Transmissions

The future of push button transmissions is uncertain. Some experts believe that push button transmissions will eventually replace traditional gear selector levers in all vehicles. Others believe that push button transmissions will continue to be a niche product, used only in certain types of vehicles.

Conclusion

Push button transmissions have come a long way since their introduction in the 1950s. They offer several advantages over traditional gear selector levers, including ease of use, convenience, and safety. However, they also have some disadvantages, including cost, reliability, and lack of driver feedback. The future of push button transmissions is uncertain, but they are likely to remain a popular option for many drivers.
