Honda Genuine Manual Transmission Fluid 08798-9031

Honda Genuine Manual Transmission Fluid (MTF) - Part #08798-9031

If you're changing the fluid in your Honda or Acura manual transmission, run the real stuff. This is Honda Genuine Manual Transmission Fluid, part number 08798-9031, the exact MTF Honda engineered for their own gearboxes. It's not a "compatible" aftermarket fluid and it's not a "meets spec" universal gear oil. Honda built their manual transmissions around a specific fluid chemistry, and they formulated this MTF to their own proprietary viscosity and additive spec that the generic stuff just can't match. So when you pour this in, you're putting in exactly what your transmission was designed to run. Your synchros shift clean, your gears stay protected, and you're not gambling on whether some universal fluid is close enough. Whether you're doing a routine fluid change on your daily, refreshing a B-series box, or filling up after a K-swap, this is the correct fluid with zero guesswork.

Why You Don't Want To Cheap Out With Universal Fluid

Here's the thing a lot of people learn the hard way. Your Honda manual transmission is engineered around this specific fluid, and running something else, even a fluid with "compatible" printed right on the bottle, can cost you. The wrong chemistry leads to notchy, crunchy shifts, and over time it wears your synchros and can damage your bearings. None of the universal MTFs on the market actually match Honda's factory spec, no matter what the label claims. That's a lot of money in transmission damage to save a few bucks on fluid. Running the genuine 08798-9031 keeps your synchros engaging smooth and protects the transmission to the tolerances Honda's engineers built it for. On a gearbox you actually care about, this isn't where you experiment.

What It Fits

This MTF goes in a huge range of Honda and Acura manual transmissions, so odds are good it's what your car needs. That covers the Civic across the EG, EK, EP3, and FD2 chassis with their D-series and K-series gearboxes, Acura Integra DC2 and DC5 with B-series and K20A3 transmissions, and the RSX Type-S DC5 with the K20A2/K20Z1 6-speed. It's also the fluid for the S2000 AP1 and AP2 close-ratio 6-speed, 6th and 7th gen Accord F-series manuals, 1st and 2nd gen CR-V manual variants, the Element 5-speed, and the Acura TSX CL9 K24 6-speed. That said, transmissions vary by model and year, so always confirm your specific transmission code against your owner's manual or your dealer before you service it. Better to check than to guess.
