Reasons why your transmission is failing


You understand your automobile well. So, you will realize when it starts behaving abnormally. Do you hear some sounds, or is there some odor coming from your car? In this case, the most essential is to diagnose the cause of these problems properly. After the diagnosis process, the expert will use high-quality Allison Transmission parts to solve the issues. Here are some of the signs that you might need a transmission repair.

Signs that your transmission has a problem

Allison is a reliable company when it comes to transmission repair, and they will use genuine Allison Transmission parts. What makes us stand out is our comprehensive diagnostic approach, together with expertise and knowledge to know the cause of the problems. You might be experiencing issues with your transmission if your automobile is showing anyone these signs.

Transmissions failing to engage or remain in gear

In case you engage your gear and the car fails to move, this might be an issue with lower transmission fluid caused by a leak, shifter cable, and shifter. Or it can be an issue in the valve body of the automatic transmission. Recent vehicles rely on a computer to direct the transmission when to go into gear, depending on your choice. So, you might need to have a computer system diagnosed for trouble codes.

Delayed shifts or missing gear

If the transmission takes a long duration to go into gear, you might have a lower transmission fluid issue due to a leak or contamination caused by lack of maintenance. This can also be caused by water intrusion during flooding or off-road conditions. Even though this might not seem serious, it can cause overheating that will destroy the internal transmission components. Another likelihood can be the engine-related issue that will make the computer prevent the transmission from shifting into high gears.

Transmission slipping or engine is revving higher

This state can be caused by lower transmission fluid, contamination because of lack of proper maintenance, or water intrusion. Other causes include internal wear and tear on internal transmission components. A higher revving engine is a common sign that the clutches are worn out, or other components inside the transmission are damaged.

Leaking of transmission fluid

The red liquid under the car is a great sign that the transmission fluid leaks from the cooler lines, seal, or gasket. At the same time, this is not good for transmission; it’s risky if the liquid leaks on a hot surface or pipe. Make sure you check the dipstick for the required fluid level and state. Bear in mind that not all transmission liquids are read, and not all fluid levels can be verified with the dipstick technique but need special equipment.

Presence of a burning smell

Typically, a burning odor is caused by a liquid leak or low fluid, making a burning clutch smell. If you notice a fluid leak on time, you might save the transmission from going bad. Check out the transmission dipstick to determine the condition and level.

Presence of clicking, buzzing or humming noise

A clicking, buzzing, roaring, or humming noise from the interior of the transmission is a sign of planetary gears damage, bad bearing or other interior issues. The noise can also originate from a bad interior sealing surface or low transmission liquid because of a leak.

The vehicle has no power

If the car has little or zero power and the engine runs perfectly, this would be caused by the internal transmission issues, dragging brakes because of the faulty caliper or brake hose, or the computer in the car restricting power due to a problem it has sensed to safeguard the engine. Get the car diagnosed for trouble codes to know the problem.

Check the engine light or overdrive lights is on

A check engine light is not designated for the engine only. Once you see a check engine light, just know there are problems with the transmission such as overheating, solenoid issues, slipping transmission, and speed detectors. Get the trouble codes removed to know what circuits and systems are showing the issue. Even though not all detector-related codes show the sensor is damaged or will fix the problem. It will help you know where to start.
