Maintaining the correct transmission fluid level is essential for keeping your Honda’s transmission healthy, smooth, and long-lasting. Although some newer Hondas have sealed transmissions without a dipstick, many models still allow you to manually check the fluid. This guide explains everything you need to know step-by-step.
How to Check Honda Transmission Fluid Level
1. Warm Up the Engine
Start the vehicle and let it run for at least 5–10 minutes to bring the transmission fluid up to operating temperature. Warm fluid expands and provides a more accurate reading.
2. Shift Through All Gears
With your foot on the brake, slowly shift the gear selector through all positions, P, R, N, D, and lower gears, pausing for 1–2 seconds in each. This circulates the fluid throughout the transmission.
Return the gear selector to Park (P) for most Honda models, unless your owner’s manual specifies Neutral.
3. Leave the Engine Running (for Most Hondas)
Most Honda vehicles require the fluid to be checked with the engine idling, unlike some brands that recommend checking with the engine off.
However, always verify with your owner’s manual, especially for newer CVT Hondas.
4. Locate the Transmission Dipstick
On models that have one, the dipstick is usually:
- Near the front of the engine bay
- Marked with a yellow or orange handle
- Labeled “Transmission” or “ATF”
CVT-equipped Hondas often do not have a dipstick, and checking requires a fill/inspection plug underneath. In this case, the procedure should be done by a technician.

5. Remove and Clean the Dipstick
Pull out the dipstick carefully.
Use a clean cloth or paper towel to wipe it completely.
6. Reinsert the Dipstick Fully
Push the dipstick all the way in, making sure it seats properly. Wait a couple of seconds, then pull it back out to get an accurate reading.
7. Check the Fluid Level
Observe the markings:
- HOT / FULL – upper level marks for warm fluid
- LOW / ADD – lower marks
The fluid should be between the two HOT marks if the engine is running and warm.
If it is below the lower mark, the transmission is underfilled.
8. Inspect Fluid Color and Condition
Proper Honda ATF should be:
- Clear red or pinkish
- Smooth in texture
- Not burnt or dark brown
If the fluid smells burnt or is very dirty, a fluid change is recommended.

9. Add Transmission Fluid If Needed
If the level is low:
- Use only Honda ATF, such as Honda ATF-DW1 for conventional automatics or Honda HCF-2 for CVTs.
- Add small amounts at a time through the dipstick tube.
- Recheck the level after each small top-up.
Never overfill, as too much fluid can cause foaming, overheating, and transmission damage.
10. Reinstall the Dipstick and Clean Up
Make sure the dipstick is firmly reinserted to prevent leaks.
Wipe away any spilled fluid.
Signs Your Honda Transmission Fluid Needs Attention
Even if your fluid level is correct, other symptoms may indicate service is needed:
- Slipping between gears
- Shuddering or jerking
- Delayed shifting
- Whining or grinding noises
- Transmission overheating warning
- Dark or burnt-smelling fluid
Addressing these signs early can prevent major failures.

How Often Should You Check Honda Transmission Fluid?
Honda recommends checking transmission fluid every 6,000–10,000 miles, or at every oil change. If you tow, drive in heavy traffic, or live in very hot climates, check it more often.
For CVT models, check every 25,000–30,000 miles; however, note that many CVTs do not have a dipstick.
Can You Drive with Low Transmission Fluid?
You should avoid it. Low fluid leads to heat buildup and mechanical wear, which can quickly destroy a transmission. If the fluid is very low, do not drive until you top it up.
FAQs
Do you check Honda transmission fluid with the car running?
Yes, most Honda models require checking the transmission fluid with the engine running and warmed up. This gives an accurate reading because transmission fluid expands at operating temperature. Some CVT-equipped Hondas follow a different procedure, so always verify in your owner’s manual.
How can I tell if my transmission fluid is low?
Signs of low transmission fluid include delayed or rough shifting, slipping between gears, shuddering, jerking, overheating, or unusual whining noises. You can also confirm low fluid by checking the dipstick, if the level is below the lower HOT mark, your fluid is low.
Do you check transmission fluid when it’s hot or when it’s cold?
For Hondas, you typically check transmission fluid when it is hot, meaning the engine has been driven and is at normal operating temperature. Warm fluid expands and provides a more accurate reading. Cold readings are only used on rare models that include a cold level range.
How to check transmission fluid on 2018 Honda Civic?
The 2018 Honda Civic (especially CVT models) does not have a traditional dipstick. Instead, it uses a sealed transmission system with a fill/inspection plug underneath. To check the fluid level, the vehicle must be lifted, the fluid brought to the correct temperature range, and checked from the inspection plug. This is best done by a technician or dealership using proper tools and service procedures.
How to check Honda automatic transmission fluid level?
- Park on a level surface.
- Warm up the engine for 5–10 minutes.
- Shift through all gears, ending in Park.
- Leave the engine running (for most models).
- Locate and remove the transmission dipstick.
- Wipe it clean, reinsert, then pull it out again.
- Check that the fluid level is between the HOT marks.
- Add Honda ATF if needed, using small amounts.
Final Thoughts
Checking your Honda transmission fluid level is an essential part of routine maintenance that can help you avoid expensive repairs. With just a few minutes and simple tools, you can ensure your transmission operates smoothly and stays in good condition for the long term. Always use Honda-approved ATF, follow your owner’s manual, and inspect the fluid condition regularly.
If your Honda has a sealed transmission (especially newer CVT models), professional inspection is recommended, as these systems require specific procedures.
