Transmission Troubleshooting: Vehicle Fails Or Delays Shifting Out Of Gear

A transmission that is acting up makes driving frustrating. It can also make driving dangerous. This, in addition to the fact that ignoring the early symptoms of a malfunctioning transmission system will leave you with a completely damaged transmission system, makes it imperative to not only detect, but also fix the source of these problems.

The following are tips that will come in handy in helping you fix a system that, even though it can go into gear, fails to get out of gear.

You are low on transmission fluid

Your vehicle's transmission is basically a hydraulic system. It relies heavily on the transmission fluid to transmit pressure from one end to the other. If there is less of the transmission fluid, the process of pressure transfer will be inefficient. This may then lead to shifting failures that may then rob you of a smooth driving experience.

Since the transmission fluid is usually reused in the system, low transmission complications arise in cases where there is a leak.

Leaks occur in vehicles that have loose seals such as the input and output shaft seals. If the lines that are transmitting the fluid develop tears, leaks will also occur. They are also easy to detect as they are usually accompanied by the pooling of the transmission fluid below the vehicle and directly beneath the leak area.

To solve this problem, start by first tracing the source of the leak. Repair the leak and then refill the transmission. When doing so, keep in mind that overfilling exposes the fluid to aeration, something that may then mess with the system's effectiveness.

You have malfunctioning vehicle sensors and controls

Your vehicle's transmission system is under the direct control of the Powertrain Control Module. This device manages the transmission system based on the feedback it gets from the speed sensor. Therefore, if the speed sensor malfunctions, it will give the wrong feedback to the Powertrain Control Module. And since this device will act on wrong information, the adjustments it makes will mess with the proper working of the system. This includes causing delays or failures when it comes to the gear-change process.

The transmission system will also act up when there is shorting of any of its controls. For example, if the control solenoid of the second gear is shorted, your vehicle will always experience failure when it is time to shift into the second gear.

In cases where the source of the transmission problem is sensor and control defects, replacing the defective parts is the only solution. For more information, contact companies like Karry's Automotive Service Center.
