How To Check Transmission Fluid


Understanding Transmission Fluid and Its Importance
What Is Transmission Fluid?
Transmission fluid refers to a lubricant used in the vehicles to keep the transmission system's performance at its peak. It aids in the function of shifting gears, maintaining the temperature of the transmission, and preventing wear and tear. The transmission system plays a crucial role in a vehicle's performance, and it heavily relies on the quality and level of transmission fluid.
- It ensures smooth gear shifts
- Prevents damage to the system due to high temperature
- Keeps the components of the system clean
Why Is Checking Transmission Fluid Important?
Ensuring the correct level and quality of transmission fluid is vital for the vehicle's efficient performance and longevity. An underfilled or overfilled transmission can cause severe damage to the transmission, including gear slipping, overheating, and even complete failure.
- Timely checks can prevent costly repairs
- Ensuring the health of the transmission system
- Improving vehicle's fuel efficiency
Type of Transmission Fluid
Different vehicles require varying types of transmission fluid. It is essential to consult the vehicle's manual to understand the specific type your vehicle requires. The most common types include Dexron/Mercon, Hypoid Gear Oil, and Synthetic Oil.
- Dexron/Mercon is the most commonly used transmission fluid
- Hypoid Gear Oil is typically used for vehicles with high mileage
- Synthetic Oil is known for its excellent heat resistance and longer shelf-life
Step-by-Step Guide on How to Check Transmission Fluid
Prepare for the process
The checking process isn't complicated but needs careful execution. Place the vehicle on a level surface, and ensure the engine is warm. It's also crucial to have your parking brake on.
- Ensuring safety by engaging the parking brake
- A level surface gives accurate reading
- Warm transmission fluid expands and gives a correct measure
Locate the Dipstick
Much like checking the engine oil, vehicles have a dedicated dipstick for checking transmission fluid. The location of this dipstick varies from vehicle to vehicle, which makes consulting the vehicle manual a vital step before proceeding.
- The dipstick is usually marked with 'transmission'
- Some new models might not have a dipstick
- In cars without a dipstick, a plug hole or level indicator is available instead
Read the Fluid Level and Condition
After extracting the dipstick and cleaning it with a lint-free cloth, reinsert it and then pull it back out to read the level. The fluid should fall within the 'Hot' marking region. Also, assess the condition of the fluid. It should be red or pinkish and shouldn't smell burnt.
- A low level could mean leakage
- A high level might mean overfilling
- Dark or burnt smell fluid indicates a problem
