Usually the manufacturer manual that comes with your car has the transmission service recommendation. However, it is advisable to service your transmission after every 30,000 to 60,000 miles. In fact, you should stick to 30,000 miles if you use your vehicle to carry heavy loads or to tow vehicles often.
Your transmission is one of the hardest working parts of your vehicle. It converts the engine output to torque and speed so it should always be in perfect condition. People usually skip transmission service. Here is what you should know. The wear and tear in your transmission can leave metal shavings in the transmission fluid. A contaminated fluid cannot lubricate your transmission properly. So, it may lead to a major breakdown. Besides, leaving contaminated fluid in your transmission longer than recommended can also shorten the lifespan of your transmission.
Apart from the presence of metal shavings, transmission fluid gets degraded with time. In addition, it is also necessary to check the level of transmission fluid regularly as you may have a leak somewhere. Once the level reduces, it is almost certain that there is a leak. Unlike engine oil, transmission fluid does not burn out.
Even if your vehicle has not hit 30,000 miles, you may need to service your transmission if you notice any of the following signs.
- If your transmission delays before shifting gears. It is a sign that all is not well with your transmission. You need to check it or be ready for a major repair or even replacement.
- If a manual transmission begins to pop out of gear while in motion, it is another common sign of transmission problem.
- If a manual transmission emits a burning smell whenever you try to change your gear, it is either your clutch plate is gone or your transmission fluid is overheating.
- A grinding noise while shifting gears means that your transmission fluid is low or inadequate.
In conclusion, how often you service your transmission will determine how long it will serve you. So, you need to follow your manufacturer’s recommendation or service it every 30,000 miles. It can never be too often.
