Honda Manual Transmission Fluid (MTF)
Follow your vehicle's maintenance service timing of when to change manual transmission fluid. Do not attempt to check or change the manual transmission fluid yourself.
If Honda MTF is not available, you may use the API certificated SAE 0 W-20 or 5 W-20 viscosity motor oil as a temporary measure.
Replace with MTF as soon as possible. Motor oil does not contain the proper additives for the transmission and continued use can cause decreased shifting performance and lead to transmission damage.
