Know This Transmission Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this transmission family:
A quick look at your own vehicle makes sure the right transmission shows up:
- Confirm VIN 10th digit is H (2017 model year).
- Confirm VIN 4th, 5th, and 6th digits are CR6 (9th generation Accord Hybrid).
- Confirm engine is the 2.0L 4-cylinder Hybrid (LFA1).
- Locate the barcode/metal tag on the existing transmission and verify the 4-character code is MM5E.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- High-voltage safety equipment (Class 0 insulated gloves rated for 1,000V, safety glasses)
- Engine support bar or hoist
- Transmission jack
- OBD2 scan tool with Honda-specific diagnostic software (Honda i-HDS)
Budget for these consumables at install:
- Honda Genuine ATF DW-1 fluid (do NOT use standard CVT fluid)
- Main oil filter (Part Number: 25420-5Y4-003)
- Drain plug crush washer (18mm)
- Replacement axle seals (left and right side)
- Professional transmission cooler-line flush
What your vehicle’s computers will need after the swap:
What’s involved: Automatic Resolver Offset Calibration / Start Clutch Feedback Learn
Because this transmission contains two high-power electric motors, the PCM/TCM must be calibrated to the physical position of the new resolvers and clutch engagement points using a Honda Diagnostic System (HDS) or compatible bidirectional scan tool.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- High-Voltage Safety: Must disable the high-voltage system by removing the service plug and waiting 10 minutes before starting work.
- No Torque Converter: Unit bolts directly to the engine's flywheel/flexplate via a dampener plate; ensure correct alignment.
- Fluid Leveling: No dipstick is present. Fluid level must be checked via the check-bolt hole on the side of the transmission with the vehicle level.
- Subframe Removal: Many procedures require lowering the subframe for adequate access.
Easy to get right once you know them:
- Using incorrect fluid: Buying standard CVT fluid (like Honda HCF-2) instead of the required Honda ATF DW-1.
- Ordering for the wrong year or model: Attempting to install this unit in a 2018+ Accord Hybrid or a non-hybrid Accord.
- Skipping the electronic relearn/calibration procedure after installation.
- Failing to disable the high-voltage battery before beginning work.
- Not flushing the transmission cooler lines to clear out debris from the previous failed unit.
Not issues with the units on this page — the manufacturer documented these for every transmission of this family, wherever you buy one. Handy for your installer:

- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance

This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included

Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion

- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
