    This article is applicable to all Honda cars with Automatic or CVT Transmission\gearboxes.

    The Background
    It is important to keep the transmission fluid at the correct level in automatic and CVT-transmissions.If the fluid is above the upper level of the dipstick, the fluid is agitated excessively, especially at high speeds.This can cause aeration or foaming, which can result in reduced lubrication, mis-shifting, fluid blow-out and early deterioration of the fluid due to excessive heating. If the fluid is below the lower level of the dipstick, this can result in reduced lubrication, mis-shifting, abnormal noises from the transmission and early deterioration of the fluid due to excessive heating.

    Please follow the following guidelines to make sure the transmission fluid is at the correct level.

    During production, the transmission is filled with an exact amount of transmission fluid. This amount
    guarantees that the level will be between the upper and lower mark on the dipstick.

    When inspecting the transmission fluid level, follow the procedure :

    1. Park the car on a level ground and run the engine to it's normal operating temperature (the fan comes on twice).

    2. Shut down the engine.

    3. Within 90 seconds, check the transmission oil level.

    4. It should be between the lower and upper marks.

    5. If it is, the fluid level is OK.

    6.Do not add any fluid to reach the upper mark ! If the fluid is above the upper mark, drain enough fluid to bring the level below the mark.

    Index
    A = Dipstick
    B = Upper level
    C = Lower level
    D = OK
    E = Oil level too high

    ATF\CVT fluid Replacement
    1. Drain the transmission oil.
    2. Refill the transmission with the recommended amount as shown in the shop manual and owner's manual.
    3. Perform the inspection procedure as described above.
    4. Make sure the fluid level is between the upper and lower level on the dipstick.
    5. Do not add any fluid to reach the upper mark ! If the fluid is above the upper mark,drain enough fluid to bring the level below the mark.
