If your 2008 Honda Civic’s transmission is starting to hesitate, shudder, or shift harder than it used to, you are not alone — a delayed shift is often the first sign the fluid has lost its friction grip. The right fluid for a Civic of this vintage is either the genuine Honda DW-1 or a premium synthetic that meets the same H-Plus specification, and the difference between picking the right one and the wrong one shows up in how smoothly the car drives for the next 50,000 miles.
I’m Min Islam — the founder and writer behind Trending Car. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
This breakdown covers the three best automatic transmission fluids for your 2008 Civic, from a budget-friendly single quart to a complete service kit, so you can find the right 08 honda civic transmission fluid for your next drain and fill.
Our Picks at a Glance
How To Choose The Best 08 Honda Civic Transmission Fluid
Your 2008 Civic’s automatic transmission is a delicate piece of engineering that relies on specific friction characteristics to shift smoothly. Putting in a random brand of Dexron or Mercon fluid can cause shuddering or even damage over time, so stick to fluids that carry the Honda DW-1 or Idemitsu H-Plus specification. The three picks below all meet that standard, but they differ in how much you get and whether the kit includes the crush washer you need for the drain plug.
The DW-1 vs. H-Plus Difference
Honda originally filled your Civic’s transmission with ATF-Z1, then superseded it with DW-1. Idemitsu, the actual manufacturer of Honda’s factory fluid, sells its own version under the Type H-Plus name. Both fluids deliver the exact same frictional behavior and anti-shudder performance — the main difference is the bottle label and the price per quart.

In‑Depth Reviews
1. Idemitsu ATF Type H-Plus Automatic Transmission Fluid – 1QT
Our pick — over 4.5★ from 850+ verified ratings; the strongest balance of quality and price.
The synthetic H-Plus fluid from the same Japanese maker that supplies Honda’s factory fill.
Idemitsu is the actual manufacturer behind much of Honda’s branded ATF, so this Type H-Plus fluid is chemically very close to the genuine DW-1 you would buy from a Honda dealer. The key advantage here is cost: a single quart weighs just 1.9 pounds and costs significantly less per quart than the Honda-branded alternatives. This makes it a smart choice if you are topping off a low level rather than doing a full drain and fill, or if you plan to do multiple drain cycles on a tight budget.
Customers note using this fluid across multiple Honda and Acura vehicles for years, with one owner noting nearly 300,000 miles of smooth shifting across their fleet. The fluid is engineered for enhanced fuel economy, superior low-temperature flow, and excellent resistance to oxidation and thermal breakdown — all of which matter for a 2008 Civic that may see cold starts in winter and heat buildup in summer traffic. If you need a full service, you will need three or four of these bottles since one quart only covers about a third of what the transmission holds.
Reasons to pick it
- Made by Idemitsu, the same manufacturer that supplies Honda’s own DW-1 fluid
- At 1.9 pounds per quart, it is the lightest option for simple top-offs
- Proven long-term performance: reviewers point out 300K miles of trouble-free shifting
The drawback
- Single quart means you need to buy three or four for a full drain and fill on the Civic
Best for low-budget top-offs: If you just need to bring the fluid level back up between services, this single quart of Idemitsu is the most affordable way to do it with the correct H-Plus spec.
Not ideal for full service: For a complete drain and fill, the four-quart Honda kit above gives you enough fluid and a crush washer in one purchase.
2. Honda Genuine ATF DW-1 Automatic Transmission Fluid (4 Quarts) + 18 mm Drain Plug Washer
The no-guesswork kit that gives you every drop and the fresh crush washer your drain plug needs.
This is the simplest way to service a 2008 Civic transmission correctly on the first try. The kit includes four 1-quart bottles of genuine Honda ATF DW-1 (the exact fluid your car was designed for) plus one 18 mm aluminum drain plug washer (part number 90471-PX4-000). A standard drain and fill on a Civic takes about 3 to 3.5 quarts, so you have enough for the job plus a full quart left over for a top-off later — or enough to start a second drain cycle if you do the triple-cycle method.
Buyers report doing a complete triple cycle drain and fill on a Honda Fit with this kit, noting it is exactly what the car needs and the washer is a welcome inclusion. The official Honda formula ensures the transmission shifts smoothly because the friction modifiers are tuned specifically for Honda’s clutch pack design. At 7.5 pounds total, this kit is noticeably heavier than a single quart — but you are getting four times the fluid plus a part you would otherwise have to buy separately.
Why grab this kit
- Includes the 18 mm aluminum crush washer so you don’t have to hunt for one
- Four quarts cover a drain and fill with a full quart to spare
- Genuine Honda DW-1 formula matches the factory fill exactly
One thing to keep in mind
- At 7.5 pounds, it weighs more than a single quart of Idemitsu at 1.9 pounds — that is the weight of four bottles plus the washer, not a dealbreaker
Your best bet for a first service: If you are doing your first drain and fill on a 2008 Civic and want one order that includes everything, this kit saves you a second Amazon trip.
The trade-off to know: The price per quart is higher than buying a generic synthetic, but the included washer and OEM assurance justify the premium for most owners.
3. Genuine Honda 08200-9008 Automatic Transmission Fluid ATF DW-1 (ATF-Z1) 2 Quarts
The exact Honda fluid in a two-quart pack that is ideal for a partial drain or topping off after a service.
This is the same genuine Honda DW-1 fluid that the four-quart kit above contains, just in a smaller two-quart package. If you have already done a drain and fill and only need to top off after checking the level, or if you are doing a single drain (which typically yields about 3 quarts out), these two bottles give you enough fresh fluid to refill what came out. The fluid is the official replacement that superseded ATF-Z1, so it is backward compatible with your 2008 Civic’s original fill.
Buyers with high-mileage Honda vehicles report excellent results: one owner of a 2012 Odyssey with 140,000 miles says the transmission still runs like new after sticking with ATF-DW1. The two-quart format weighs 3.77 pounds, while the four-quart kit weighs 7.5 pounds, making it easier to handle if you only need a partial fill. Unlike the premium kit above, this package does not include a drain plug washer, so you will need to source a separate 18 mm washer (part 90471-PX4-000) if yours is worn.
What works well
- Genuine Honda DW-1 formulation for exact OEM shift quality
- Two quarts give you enough for a single drain-and-refill on the Civic
- Proven long-term track record — owners mention 140K+ miles with smooth shifting
Where the kit falls short
- No crush washer included, so you may need to buy one separately
Reach for this if: You already have a fresh crush washer and only need two quarts to complete a fluid change or top-off on your 2008 Civic.
Look elsewhere if: You want a single order that covers an entire service with a new washer — the four-quart kit makes more sense for first-timers.
Understanding the Specs
DW-1 vs. H-Plus: What Is the Difference?
DW-1 is the current Honda-spec automatic transmission fluid that replaced the older ATF-Z1 around 2012. It has a lower viscosity for better fuel economy and improved cold-weather flow. Idemitsu Type H-Plus is the same base formulation sold under the Idemitsu brand, since Idemitsu actually manufactures Honda’s ATF. For your 2008 Civic, both are fully compatible and interchangeable — the main difference is the bottle label and the price per quart.
How Many Quarts Does a 2008 Civic Need?
A standard drain-and-fill on a 2008 Honda Civic automatic transmission drains roughly 3 to 3.5 quarts of the roughly 7.5-quart total capacity. That means you replace less than half of the old fluid with each service. For a complete flush, you would need to do a triple-cycle drain (drain, fill, run through the gears, drain again, repeat). The four-quart kit gives you enough for one reliable drain and fill with a little left over. If you plan to do multiple cycles, you will need at least two of the four-quart kits or several single quarts of Idemitsu.

Final Thoughts: The Verdict
For most 2008 Civic owners, the best 08 honda civic transmission fluid choice is the Honda Genuine ATF DW-1 4-Quart Kit because it gives you the exact OEM fluid, enough volume for a full drain and fill, and a new crush washer in one order. If you already have a washer and just need to top off a low level, grab the Idemitsu ATF Type H-Plus Single Quart for the lowest per-quart cost. And for a middle-ground option that covers a partial service without the extra weight of a full kit, the Genuine Honda 2-Quart Pack is the right fit.
