How to Preserve Car Transmission


The transmission is a vital component of a car, responsible for transferring power from the engine to the wheels. It allows the driver to change gears, which changes the car’s speed and torque. A well-maintained transmission will last for many years, but there are some things you can do to help preserve it and extend its lifespan.

1. Change the Transmission Fluid Regularly

The transmission fluid is a vital lubricant that helps to keep the transmission components moving smoothly. It also helps to dissipate heat and prevent wear and tear. The transmission fluid should be changed every 30,000 to 60,000 miles, depending on the type of transmission and the driving conditions.

2. Avoid Harsh Shifting

Harsh shifting can put stress on the transmission and cause damage to the gears and other components. When shifting gears, do so smoothly and gently. Avoid slamming the gearshift into place, as this can shock the transmission and cause premature wear.

3. Don’t Overload the Vehicle

Overloading the vehicle can put excessive strain on the transmission. When the vehicle is overloaded, the transmission has to work harder to move the heavier load. This can lead to overheating, wear and tear, and even transmission failure.

4. Avoid Towing Heavy Loads

Towing heavy loads can also put stress on the transmission. When towing a heavy load, the transmission has to work harder to move the additional weight. This can lead to overheating, wear and tear, and even transmission failure. If you need to tow a heavy load, be sure to use a vehicle that is properly equipped for the task.

5. Have the Transmission Inspected Regularly

A regular transmission inspection can help to identify any potential problems before they become serious. During an inspection, the mechanic will check the transmission fluid level and condition, the gears, and other components. The mechanic may also recommend some preventative maintenance, such as a transmission flush or filter change.

6. Drive in the Correct Gear

Driving in the correct gear can help to preserve the transmission. When driving, always select the gear that is appropriate for the speed and driving conditions. Driving in too high of a gear can put strain on the transmission, while driving in too low of a gear can lead to overheating.

7. Avoid Riding the Brake

Riding the brake can put stress on the transmission. When you ride the brake, the transmission has to work harder to keep the vehicle from moving. This can lead to overheating, wear and tear, and even transmission failure.

8. Park the Vehicle in Neutral

When parking the vehicle, always put it in neutral. This will help to prevent the transmission from being damaged if the vehicle is accidentally bumped or rolled.

9. Use a Transmission Cooler

A transmission cooler can help to keep the transmission fluid cool, which can extend the life of the transmission. A transmission cooler is a small radiator that is installed in the cooling system. It helps to dissipate heat from the transmission fluid, which can prevent overheating and premature wear.

10. Follow the Manufacturer’s Recommendations

The best way to preserve the transmission is to follow the manufacturer’s recommendations for maintenance and service. The manufacturer’s recommendations will include the recommended transmission fluid change intervals, as well as any other preventative maintenance that is necessary.


By following these tips, you can help to preserve your car’s transmission and extend its lifespan. A well-maintained transmission will provide years of trouble-free service, and it will help to keep your car running smoothly and efficiently.
