Transmission fluid is an important part of keeping your car running smoothly. It lubricates the parts that move, cools the transmission and helps your car shift gears correctly. Low, dirty or contaminated fluid can cause poor fluid performance and costly repairs.
Learning how to check transmission fluid is an easy maintenance that can help extend the life of your car and avoid catastrophic transmission problems.
Transmission fluid does the following :
Lubricate parts of transmission
Do not over heat
Make sure gear change smoothly.

Checking the Transmission Fluid What You’ll Need Before Checking
Get these first before you begin:
Lint free cloth or paper towel.
Gloves
Vehicle’s Owner’s Manual
Funnel (for pouring liquids)
Some vehicles have specific procedures or sealed transmissions, so you'll need the owner's manual.
Park the car on level ground. Apply parking brake for safety.
A level surface will provide a more accurate reading of the fluid.
Most cars require checking transmission fluid with a hot engine.
Start the engine and idle it for about 5-10 minutes. Some manufacturers recommend a short drive before checking the automobile.
Leave the engine running unless your manual tells you otherwise.
Open the hood and locate the transmission dipstick.
Usually it is:
red, yellow, orange to the rear of the engine compartment
— Subtitled “Transmission”
Don't mix it up with the engine oil dipstick.
Some newer cars have sealed transmissions and do not use dipsticks.
Slowly pull out the dipstick.
Wipe the fluid really well with a clean cloth/paper towel.
This will remove old residue and give you a more accurate reading.
Push the dipstick all the way back down the tube.
Slowly pull it out to see how much fluid there is.
See what the dipstick says.
You will often see indicators such as:
Full Add Hot Chill
The fluid should be in the suggested range.
If the level is low, you may need to top up with the correct type of transmission fluid for your car.

Good Transmission Fluid
Bright Red or Pink
Great view
smell sweetish
Transmission fluid (smelly)
Color Black to brown dark
Smell of something burning.
polluted or dirty-looking
If the fluid appears dirty or smells burnt you may need to change your transmission fluid.
Adding Transmission Fluid To
Low on transmission fluid If you have:
Put a funnel in the dipstick tube
Add the proper fluid one small amount at a time
Recheck the level each time you add something
Don’t overstuff it
Always stick to the manufacturer’s recommendation, as using the wrong fluid may damage the gearbox.
Good rule of thumb is check transmission fluid.
Monthly Road trips Pre-trip During regular oil changes
Most cars require the gearbox fluid to be changed every 30,000 to 60,000 miles, but this depends on the model.
Sealed gearbox for vehicles
Many modern cars have sealed transmissions without a dipstick.
In the vehicles.
Fluid testing might need special equipment
May need to lift the car up
Fluid temperature may need to be observed
If you have a sealed system, see your professional mechanic or your owner’s manual.
What to Watch Out for When Checking Fluid on an Uneven Surface
This could lead to an incorrect reading.
Incorrect Transmission Fluid
Different cars require different fluids.
Transmission Overfill
Too much fill will cause pressure problems and destroy seals.
Dirty Fluid Bypass
Never ignore any dark or burnt fluid.
Benefits of Regular Transmission Fluid Checks
Maintenance can help in general:
Avoid a transmission breakdown
Improve vehicle performance
Extend transmission life
Lower maintenance costs
Make sure your gear changes are smooth
Just a few minutes of inspection can save you thousands in repairs later.
Yes, the gearbox fluid of most vehicles can be checked at home using the dipstick.
