It’s widely known that regular maintenance is the best way to keep your vehicle running its best. Giving a quick check-up on your transmission fluid is one of the most basic yet most important maintenance responsibilities you can carry out to keep your vehicle running as it should. Transmission fluid guarantees your transmission operates correctly, no matter if it’s a manual or automatic transmission. When the fluid level gets too low or gets too contaminated, it can result in serious and expensive transmission issues.
The following is a guide on how to check your transmission fluid level.
Understanding the Duty of Transmission Fluid
Transmission fluid acts as a lubricant for the moving components inside your transmission, hindering overheating, decreasing friction, and maintaining the system’s cleanliness. In vehicles with an automatic transmission, it additionally functions as a hydraulic fluid, aiding in transferring power between parts. Maintaining the proper level and quality of transmission fluid guarantees smooth shifting, the ideal performance, and a longer service life for your vehicle’s transmission.
Degraded or low transmission fluid can lead to a multitude of noticeable issues like:
- Gear slippage
- Shifting delays
- Unusual noises such as clunking, whining, or grinding
- A smell of burning
- A warning light for increased transmission temperature
- Brown or red pools underneath the vehicle
Deal these symptoms sooner than later by checking the transmission fluid so you can prevent additional damage.
How to Check Your Transmission Fluid
Step 1: Find the Transmission Dipstick
To check your transmission fluid, begin by opening the hood of your vehicle and locating the transmission dipstick. It’s usually labeled with a bright handle, typically yellow, orange, or red, making it easily identifiable.
For vehicles with an automatic transmission, the dipstick is commonly found near the back of the engine bay near the firewall. If you’re driving a vehicle that has a manual transmission, you might not find a dipstick at all. Rather, manual transmissions usually require fluid levels to be checked via a fill plug located on the transmission’s housing.
If you’re uncertain where the dipstick or fill plug can be found, go over your vehicle owner’s manual for assistance.
Step 2: Check Transmission Fluid Levels
- With the vehicle’s engine running and the vehicle in “Park” (automatic) or neutral (manual), pull the dipstick out of the transmission tube.
- Wipe it clean with a paper towel or cloth to remove any remaining fluid, after that reinsert it completely back into the transmission tube.
- Pull the dipstick out once more to check the fluid level. You are going to see indicators on the dipstick, typically marked “Full” and “Add.” The fluid level is going to need to fall within this range for correct operation.
When the fluid level falls below the “Full” mark, you are going to need to add more transmission fluid.
Step 3: Add Transmission Fluid
When the transmission fluid level is low, use a funnel and pour the correct type of transmission fluid gradually, a little bit at a time. Be cautious not to overfill the system since too much fluid could cause foaming, overheating, and shifting issues.
After you’ve added fluid, re-check the level to verify it’s within the level that is recommended.
How to Decipher Transmission Fluid Color and Smell
The transmission fluids color and smell are perfect indicators of the general health of your transmission. Transmission fluid that is in good shape is going to be vividly red and clear, whereas older, oxidized fluid could turn brown or dark red. If the fluid appears black or smells like it’s been burnt, it indicates overheating or contamination, which could result in transmission damage. Under some circumstances, a milky appearance could suggest coolant or water contamination, which is going to be a more serious problem.
If you notice any of these indications, additional inspection is required and consider having the transmission fluid either flushed or replaced. If you’re not comfortable carrying it out yourself, have a skilled mechanic carry it out for you.
