2008 Honda Accord Transmission Fluid Type | DW-1 & MTL

The 2008 Honda Accord automatic transmission takes Honda ATF-DW1 fluid, while the manual version uses Honda MTL or 75W-80 GL-4 gear oil.

Use the correct 2008 Honda Accord transmission fluid type and the 4-speed automatic keeps shifting smooth for another 100,000 miles. The LX, EX, EX-L, and V6 trims all rely on the same traditional automatic that needs genuine Honda ATF-DW1. The Sport’s 5-speed manual is a different animal entirely and requires Honda MTL or a 75W-80 GL-4 synthetic gear oil. One wrong bottle at the auto parts store can turn a routine fluid change into a transmission rebuild—so getting the exact spec right before you jack the car up matters.

What Transmission Fluid Does A 2008 Honda Accord Take?

Every 2008 Accord automatic—whether 4-cylinder or V6—uses the same transmission: a 4-speed unit that originally shipped with ATF-Z1 from the factory. In 2011 Honda replaced Z1 with ATF-DW1 (part number 08200-9008) and officially confirmed that DW-1 is backward-compatible with all vehicles that previously called for Z1. So for the 2008 model, DW-1 is the current correct fluid. The manual transmission found in the Sport trim uses a completely different lubricant: Honda MTL or any 75W-80 GL-4 rated full synthetic gear oil.

Never substitute CVT fluid or any bottle labeled “ATF/CVT Combo” in the 2008 Accord. That car uses a geared automatic, not a continuously variable transmission, and the wrong fluid chemistry can cause hard shifts or internal damage within a few hundred miles.

How Much Fluid and Where To Get It

A standard drain-and-fill on the automatic replaces about 3.5 quarts. The total system capacity is roughly 7 quarts, but the torque converter traps about half that volume behind the transmission case—it never drains through the plug. So one drain-and-fill changes roughly half the old fluid. Many owners do the job two or three times over consecutive oil changes to fully refresh the system without needing a machine flush.

The manual transmission needs 2.5 to 3 quarts of GL-4 rated 75W-80 oil. This is not automatic transmission fluid, and pouring ATF into a manual gearbox ruins the synchronizers.

Genuine Honda ATF-DW1 is available at most auto parts stores and online. A single quart bottle runs $8 to $12 depending on the retailer. A four-pack of the genuine fluid costs more, while generic Dexron VI fluids labeled “compatible with Honda and Acura” can be a few dollars less per quart. Fram and O’Reilly both sell Dexron VI options that some owners use, but the factory-spec DW-1 removes all guesswork. For the manual, Red Line MTL 75W-80 is a common aftermarket choice that meets the GL-4 requirement.

How To Change The Fluid Yourself

Changing the automatic transmission fluid on a 2008 Accord is a one-hour driveway job with one catch that trips up first-timers: check the level with the engine off. Most cars want the engine running during the dipstick check. On this Honda, running the engine during the check gives a falsely high reading that leads to underfilling or overfilling.

1. Drain. Warm the car with a short drive. Park on a level surface and use jack stands. The drain plug under the transmission accepts a 3/8″ ratchet. Let the fluid drain completely. Replace the crush washer and torque the plug to 36 ft-lb.
2. Fill. Remove the dipstick—it is under the air snorkel, which requires removing one 10mm bolt. Use a long funnel to add 2.5 quarts through the dipstick tube. Wait 15 minutes for the fluid to settle, then add another 0.5 to 1 quart to reach 3.5 quarts total.
3. Check. With the engine off and the fluid hot, read the dipstick. The level should sit between the two dots. Drive the car through all gears, then re-check. Add small amounts if low; drain slightly if over-full. The iFixit ATF replacement walkthrough covers the full sequence with torque values and photos.

One more thing: drain-and-fill leaves old fluid in the torque converter, so the dipstick read at the end of step 3 may look darker than fresh ATF. That is normal. Repeating the process after a few thousand miles clears out the rest.

FAQs

Can I use ATF-Z1 instead of DW-1 in my 2008 Accord?

Yes—Z1 was the original factory fill and works fine in a 2008 Accord. But Honda superseded Z1 with DW-1 in 2011, and DW-1 is now the recommended fluid everywhere. If you still have Z1 on the shelf it will do the job, but DW-1 is easier to find and is the current standard for a reason.

Is it true that I check the fluid with the engine off on this car?

Yes, and it is the most common mistake owners make. The 2008 Accord automatic requires the engine to be off and the fluid hot for an accurate dipstick reading. Checking with the engine running gives a level that looks high even when the transmission is low, which leads to underfilling.

How often should I change the transmission fluid on a 2008 Accord?

Honda recommends inspecting the fluid every 30,000 miles and replacing it every 60,000 to 90,000 miles under normal driving conditions. If you tow a trailer or spend most of your time in stop-and-go city traffic, shift that interval closer to every 60,000 miles for the best protection.
