Is It Possible to Push Start an Automatic Car? Exploring the Feasibility

Push starting an automatic car is generally not feasible, as it relies on hydraulic pressure to engage the gears. However, older models and some specific features might allow for a push start. This article delves into the mechanics of automatic transmissions, safety concerns, and potential alternatives for starting an automatic vehicle.

Automatic Car Mechanisms

Automatic transmissions in modern cars use a hydraulic system to engage the gears. This system is driven by the engine, and without the engine running, there is no hydraulic pressure to create the necessary engagement. This is why attempting to push start an automatic car is not advisable. The primary component responsible for hydraulic pressure, the oil pump, is located behind the torque converter, which means it requires the engine to be running to function effectively.

Historical Context and Older Models

In the 1950s and early 1960s, some cars had a pump located in the back of the transmission, which could be activated by pushing the car at a low speed. This method was not feasible for modern vehicles due to the design changes in the automotive industry. Contemporary automatic transmissions use a different system that lacks the mechanical linkage needed to engage the gears manually.

Alternatives for Starting an Automatic Car

If an automatic car runs out of battery, the best method is to use jumper cables from another vehicle to provide a boost. This ensures that the car can start safely and effectively. It is crucial always to consult the vehicle’s owner manual for specific instructions and safety precautions.

Special Features and Vehicle Types

Some older models, such as certain GM and Chrysler vehicles, had a rear pump that could be activated by pushing the car up to 30 mph. This feature was particularly useful in emergency situations. However, modern vehicles do not have these features. Additionally, modern computer-controlled vehicles have strict voltage requirements, often needing around 11-12VDC to initiate the starting sequence. This means that the only reliable way to start these cars is by using jump cables.

Modern Challenges and Solutions

In recent years, push starting automatic cars has become even more challenging due to the reliance on engine RPM for the fluid pump. The torque converter in modern vehicles is not designed to drive the fluid pump manually. Therefore, attempting to push start a modern automatic car can lead to damage or even injury if attempted incorrectly.

For those facing a dead battery, a reliable solution is to carry jumper cables. Additionally, power packs or portable jump starters are highly recommended for emergency situations. These devices can provide the necessary boost to start your car without the need for another vehicle.

For cases where the starter has failed, it’s essential to replace it rather than attempting a push start. This can be more costly and dangerous than simply replacing the starter, especially if the failure is due to an electrical issue like leaving the lights on.

Other alternatives to consider include solar chargers, which can be useful if you are far from a power source. These devices charge the battery slowly but effectively.

Remember, the best practice is to maintain your vehicle’s battery and electrical systems to prevent such situations from arising in the first place. Regular maintenance, timely replacements, and understanding your vehicle’s systems can help you avoid the frustration of a dead battery or a malfunctioning starter.
