Tools you need for transmission fluid on a 2018-2022 Honda Accord

Must-have tools
  1. 3/8 in drive ratchet (fits square drain plug)
  2. 17 mm socket, 3/8 in drive
  3. Fluid transfer pump with long hose
  4. Torque wrench, 3/8 in drive, 10-60 ft-lb
  5. Floor jack and 2 jack stands

The 10th-gen Accord dropped the transmission dipstick, so this job is a plug-out, plug-in exercise: drain from the bottom of the case, refill through a side port with a hand pump until fluid just weeps back out. Mechanically it is easy — the awkward parts are getting the splash shield off, reaching the fill port with a hose, and not overtightening plugs that thread into aluminum.

What changes by engine is the fluid and the level check. The 1.5T's CVT takes Honda HCF-2 and only HCF-2. The 2.0T's 10-speed and the hybrid's e-CVT take Honda ATF Type 2.0, and the 10-speed's level is verified in a specific fluid temperature window, which really wants a scan tool reading live data. The mistake people make most often is draining before checking that the fill plug will actually come out — do that step first, every time.

Complete tool and parts list

ItemType
Floor jack
2 ton minimum, low profile
Lifts the car level at the front subframe jack points.
Requiredshop
Jack stands
2 or 3 ton, pair
Supports the car; the vehicle must be level for an accurate fluid level check.
Safetyshop
Wheel chocks
Rubber pair
Blocks the rear wheels while the front is raised.
Safetyshop
Socket set
10 mm socket, 3/8 in drive
Removes the lower engine splash shield bolts for access.
Requiredshop
Trim clip pliers
Plastic push-pin removal tool
Pops the plastic fasteners in the splash shield without breaking them.
Recommendedshop
Ratchet
3/8 in drive, standard length
The drain plug on these transmissions uses a 3/8 in square recess on many units — the bare ratchet head drives it.
Requiredshop
Socket
17 mm 6-point, 3/8 in drive
Fits hex-head drain plugs and the fill/level check plug on the case.
Requiredshop
Breaker bar or short extension
3/8 in drive, 6 in extension
Gives leverage and clearance on a tight, torqued-down fill plug.
Recommendedshop
Drain pan
6 quart minimum, wide
Catches the old fluid; use a graduated pan to measure exactly what came out.
Requiredshop
Fluid transfer pump
Hand pump with 2-3 ft flexible hose, quart/gallon adapter
Pushes new fluid uphill into the side fill port; there is no dipstick tube to pour through.
Requiredshop
Torque wrench
3/8 in drive, 10-60 ft-lb range
Drain and fill plugs thread into aluminum and strip easily if overtightened.
Requiredshop
Drain plug crush washer
Honda sealing washer for ATF/CVT drain plug
One-time-use aluminum washer; reusing it invites a slow leak.
Partsshop
Honda HCF-2 CVT fluid
1.5T CVT only — approx 3.2-3.5 US qt for a drain and fill
The only fluid approved for the Accord CVT; generic 'CVT' fluid causes shudder and belt wear.
Partsshop
Honda ATF Type 2.0
2.0T 10-speed and hybrid e-CVT — approx 3.5-4.5 US qt (10AT), approx 2.5-3 qt (hybrid)
Required spec for the 10AT and the i-MMD hybrid transaxle; DW-1 is not a substitute.
Partsshop
OBD2 scan tool with live data
Reads transmission fluid temperature PID
The 10AT level check is done in a specific fluid temperature window.
Recommendedshop
Nitrile gloves and shop rags

ATF runs down your arm off the side fill port.
Consumablesshop
Brake parts cleaner
Aerosol
Cleans the case and plug area so you can spot a new leak later.
Consumablesshop
Safety glasses

Protects from hot fluid dripping while working under the car.

Differences within the 2018-2022 generation

1.5T: CVT, Honda HCF-2 fluid, roughly 3.2-3.5 quarts per drain and fill. 2.0T: 10-speed automatic, Honda ATF Type 2.0, roughly 3.5-4.5 quarts, with a temperature-dependent level check at the side plug. Hybrid: i-MMD e-CVT, Honda ATF Type 2.0, smaller capacity around 2.5-3 quarts — verify capacity in the service manual. Socket sizes are the same across all three: 10 mm for the shield, 17 mm or a bare 3/8 in drive for the plugs.

Torque specs

Transmission drain plug (CVT and 10AT)approx 36 ft-lb (49 Nm) — verify in the service manual
Transmission fill / level check plugverify in the service manual
Splash shield boltsapprox 7 ft-lb (9 Nm)

How the job goes

  1. Warm the transmission with a 5-10 minute drive so the fluid flows and carries debris out, then park on level ground, chock the rear wheels and let it cool enough to touch.
  2. Raise the front of the car at the factory jack points and set it on jack stands — keep the car level, because the fill port doubles as the level check.
  3. Remove the 10 mm bolts and push-pin clips holding the lower engine splash shield and set it aside.
  4. Locate and loosen the fill / level check plug on the side of the transmission case FIRST. If it will not come out, stop — you do not want an empty transmission you cannot refill.
  5. Position the drain pan, remove the drain plug on the bottom of the case (3/8 in square drive recess on most, 17 mm hex on some) and let it drain fully, 10-15 minutes.
  6. Measure the drained fluid. That volume, plus a small allowance, is what you put back in.
  7. Clean the drain plug, fit a new crush washer, reinstall and torque it to spec — do not guess, the case is aluminum.
  8. Pump new fluid into the fill port: HCF-2 for the 1.5T CVT, ATF Type 2.0 for the 2.0T 10-speed and the hybrid. Fill until fluid just begins to trickle back out of the port.
  9. For the 10AT: reinstall the plug, lower the car, start the engine and bring fluid temperature into the manufacturer's check window using a scan tool, then recheck the level at the check plug per the service manual procedure.
  10. Reinstall and torque the fill plug, clean the case with brake cleaner, refit the splash shield, lower the car.
  11. Start the engine, shift slowly through P-R-N-D-and back with the brake held, then drive gently and recheck for leaks at the plugs.
  12. On the 1.5T CVT, if your scan tool supports it, reset the CVT fluid deterioration/learn data, and reset the maintenance minder item.

Watch out

Fluid types and the general drain/fill-plug layout are solid for this generation, but plug head styles (3/8 square vs 17 mm hex), exact refill volumes and the 10AT temperature-window level check procedure vary — confirm plug torque and the level check steps in the Honda service manual for your specific year and transmission.

Frequently asked

Does the 2018-2022 Accord have a transmission dipstick?

No. All three drivetrains — 1.5T CVT, 2.0T 10-speed and hybrid e-CVT — check fluid level at a side plug on the transmission case with the vehicle level, not with a dipstick.

Can I use Honda DW-1 in my Accord CVT or 10-speed?

No. The 1.5T CVT requires Honda HCF-2 and the 2.0T 10-speed and hybrid require Honda ATF Type 2.0. DW-1 has the wrong friction characteristics and will cause shudder and accelerated wear.

How often should I change the fluid?

Honda's maintenance minder will call for it, but many owners on the CVT do a drain and fill every 25,000-30,000 miles and the 10AT every 30,000-50,000 miles, sooner for towing, heavy traffic or hot climates.

How much fluid comes out on a drain and fill?

Typically about 3.2-3.5 quarts from the 1.5T CVT, 3.5-4.5 from the 2.0T 10-speed and around 2.5-3 from the hybrid. Measure what drains out and put back the same amount, then confirm with the fill-port level check.
