Being a car owner, we can understand how curious you are to know about Transmission Failure. The transmission being a complex mechanical system of your vehicle, because of the immense head and friction transmission wears out faster than most other parts of your vehicle. If you own a car, then you should know in and out of Transmission to fix the problems at the earliest. Transmission problems can be one of the most stressful and expensive issues to fix and to deal with for car owners.
When it comes to your transmission, the issues that cause problems can quickly add up unless you know what to look for and how to look for it. So, what are the most common transmission problems, and how do you identify them? Let’s go over some of the most common one’s for you.
The Following are the Major Signs of Transmission Failure:

We only ship and sell OEM-Quality dismantled parts. If your vehicle exhibits any of the following symptoms, you may be experiencing a transmission problem. Go through following points to know signs of Transmission Failure:
- Transmission Slipping: If your vehicle won’t move when you put it in gear, it could be a problem with low transmission fluid due to a leak, the shifter, shifter cable, or even a problem in the valve body of your automatic transmission. Newer vehicles rely on the computer to tell the transmission when to shift gears based on your selection, and the computer system may need to be checked for trouble codes.
- Whining, Humming and Clunking: Many manual transmissions can experience shaking and grinding gear shifts. This could be due to damage to the gear system, bearings, or a clutch problem. To avoid further damage, see a trusted technician as soon as you notice it.
- Maintenance Problem: The leading cause of transmission failure for all makes of vehicles is failure to follow the manufacturer’s maintenance recommendations for the engine and transmission, such as changing the fluid and filters at the proper mileage and time, especially if you are using the vehicle in harsh or stressful conditions such as towing or hilly areas.
- Missing Gears: If your transmission takes a long time to shift into gear, you may have low transmission fluid due to a leak, contamination from a lack of maintenance, or even water intrusion during off-road or flooding conditions. While this may not appear to be a serious problem, it can cause an overheating condition that can damage internal transmission parts. Another possibility is that the computer will not allow the transmission to shift into higher gears due to an engine problem.
- Leaking Transmission Fluid: A red fluid under the vehicle indicates a transmission fluid leak from one of the cooler lines, a gasket, or a seal. This is not only detrimental to the transmission but also dangerous if the fluid leaks onto a hot pipe or other surface. Check the fluid level and condition of your dipstick. Please keep in mind that not all transmission fluid is red, and not all levels can be verified with a dipstick method without the use of special tools.
- Continuous Burning Smell: A burning clutch smell is usually caused by a fluid leak or, in some cases, by a low fluid level. If you detect the fluid leak quickly, you may be able to save the transmission. Check the level and condition of your transmission dipstick according to the manufacturer’s instructions.
- Continuous Loss of Engine Power: If the vehicle has no or little power and the engine is running properly, this could be due to internal transmission problems, dragging brakes caused by a faulty caliper or brake hose, or your vehicle’s computer limiting power due to a problem it has detected in order to protect the engine. To isolate the problem, have the vehicle checked for trouble codes.
- Blinking Engine Light: A check engine light is not only for the engine. A check engine light can also indicate transmission problems such as overheating, solenoid issues, speed sensors, slipping transmission, and many others. Obtain the trouble codes to determine which systems and circuits are indicating a problem. While not all sensor-related codes indicate that the sensor is faulty or that the problem will be resolved, they will provide you with a starting point for your investigation.
- When Shifting, the Gears Grind: When your manual transmission grinds when shifting gears, it is usually due to the clutch not releasing, worn or broken shift synchronizer rings inside the transmission, or a shifter wear or adjustment issue. Transmission oil/fluid that is low, dirty, or the incorrect fluid can also contribute to this issue in manual transmissions.
- Insensitive Clutch Pedal: A very less responsive clutch pedal usually indicates a problem with the linkage or hydraulic system that operates the clutch. If there are no hydraulic leaks, a simple adjustment or bleeding may be sufficient. A clutch pedal that grabs very hard could be the result of an adjustment, or it could be a worn clutch disc and pressure plate.
- Torque Converter: Torque converters are devices that transfer torque from the engine to the transmission and then to the vehicle’s drive wheels. If you notice slipping, overheating, or shuddering, or if the check engine light comes on, this could be a contributing factor. Most transmission problems have overlapping symptoms, so make sure to check the entire system before blaming your torque converter. Instead, it could be something less expensive that controls the torque converter.
- Solenoid Issues: Solenoids are an important component that regulates upshifting and downshifting while driving. Faulty solenoids can damage transmission, gear shifting issues, pressure issues, and diagnostic codes in your computer.
- Uneasy Sound when in Neutral:If you hear an unusual sound coming from your transmission only when you’re in neutral and not moving, it’s a good bet that your transmission or engine is to blame. The following are some of the most common issues:
- Rusted bearings
- Internal components that are loose
- Exhaust system failure
- A problem with the engine
- Dragging Clutch: A dragging clutch is a symptom that occurs in manual transmissions when the clutch disk fails to disengage the flywheel when the clutch pedal is depressed. The clutch is still spinning with the engine, making changing gears difficult to impossible. This difficulty is accompanied by a grinding noise whenever you attempt to change gears.
- Sudden Acceleration or Deceleration: Sudden acceleration or deceleration in your vehicle can indicate serious transmission problems. When a car’s engine surges, you’ll notice the vehicle speeding up or slowing down despite constant pedal pressure. The RPMs will also change.
What Makes a Transmission Pump Fail?
A transmission pump can fail for a variety of reasons. Overheating is one of the most common causes, which can be caused by faulty cooling fins on the pump.
- If the transmission fluid level falls too low, the pump may overheat and fail.
- As a result, it is critical to check the fluid level on a regular basis and add more fluid as needed. Low fluid levels can also cause damage to other transmission components.
- A lack of lubrication is one of the most common causes of transmission pump failure.
- If there is too much friction inside the transmission, a pump can fail.
- This can be caused by worn-out gears or seals.
- If these items are not replaced when they should be, the pump will be overworked and will fail.
- Seized bearings, caused by water contamination or excessive heat, are another common cause of failure.
- Worn seals can also cause the pump to leak and eventually fail. Finally, a bad electric motor can cause the pump to fail.
- Finally, if a pump is not used frequently enough, it can fail. When the car sits for an extended period of time, the oil in the pump begins to degrade, and the pump eventually fails.
If you are having transmission or transmission pump problems, have it checked out by a mechanic as soon as possible. A faulty transmission pump can cause total gear breakdown, so it is critical to have it inspected before it causes further damage.
Types of Transmission Best Fitted to your Vehicle:
- Manual Transmission: A manual transmission requires the driver to manually select all gears by using a movable gear selector and a driver-operated clutch. This transmission is also referred to as a “stick shift” or a “standard” transmission. For more information, see Manual Transmission Fundamentals.
- Automatic Transmission: A torque converter, planetary gearset, and clutches or bands are used in this transmission to automatically shift through a vehicle’s forward gears. Some automatics give the driver a limited amount of manual control over the vehicle (aside from selecting forward, reverse, or neutral mode), such as controlling upshifts and downshifts with buttons or paddles on the steering wheel or the gear selector.
- Automated Manual Transmission: An automated manual also uses a mechanical clutch; however, the action of the clutch is controlled by electronic, pneumatic, or hydraulic controls rather than by the driver via the clutch pedal. This transmission, also known as a “Direct Shift Gearbox” (“DSG”) or a “Sequential Manual Gearbox” (“SMG”), allows for either fully automatic forward gear shifts or manual shifts via the gear selector or buttons or paddles on the steering wheel.
- Continuously Variable Transmission: This transmission uses belts, pulleys, and sensors rather than gears to maintain a constant acceleration curve with no pauses for gear changes. As a result, a CVT can keep the engine operating at its peak power, increasing efficiency and gas mileage. More information is available at CVT Enters the Mainstream.
How to Diagnose Transmission Failure?
Transmission being the most used car part in your vehicle and its lifespan & durability depends on the behavior of the driver also. Even the performance of your transmission depends on your region also, like in hilly terrain your vehicle is more exposed to wear and tear. Considering normal condition, on an average transmission can have a lifespan of 150,000 miles to 200,000 miles for car and 250,000 miles to 300,000 miles for trucks.
If you are observing any of the above mentioned symptoms means, go for service immediately. Otherwise, it may end-up with complete transmission replace
