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 the vehicle is All-Wheel Drive (AWD).
- Verify the 7th digit of the VIN is 'H'.
- Confirm the engine is a 3.5L V6 (J35Y6).
- Locate the barcode label on top of the current transmission case and verify the 4-character prefix is 'Q5EZ'.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support fixture
- Subframe adapter/jack
- Professional OBD2 scan tool with Honda i-HDS capability
- Digital thermometer or scan tool to monitor transmission fluid temperature
Budget for these consumables at install:
- Honda Genuine ATF Type 3.1 (Part numbers 08200-9017 or 08268-P99-4EDAD) or ZF Lifeguardfluid 9
- Input shaft / torque converter seal
- Front axle seals
- Transmission cooler-line flush
- Honda HGO-1 (Hypoid Gear Oil) or equivalent SAE 75W-85 / 80W-90 gear oil for the PTU (approx. 0.45 quarts)
- One-time use fill, drain, and level-check plugs/washers
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn / Quick Learn procedure and TCM/PCM Software Update
The replacement transmission requires clearing old TCM adaptive values and performing a Quick Learn procedure using a dealer-level scan tool (Honda i-HDS). It must also be checked for the latest software updates per TSB 20-029. Skipping this will cause extremely harsh shifting, potential internal damage, or limp mode.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Must be fully seated (three distinct clicks) before bolting to the engine to avoid cracking the internal oil pump gear.
- Fluid Level Check Procedure: No dipstick. Must be checked via the level-check plug on the side of the case only when fluid temperature is between 104°F and 122°F (40°C and 50°C) with the vehicle perfectly level.
- Subframe Alignment: Dropping the subframe requires marking alignment or using alignment pins to prevent steering pull.
- Dog Clutch Shift Characteristics: Uses physical dog clutches for 4-5 and 7-8 shifts, causing a brief, normal hesitation that is a design characteristic, not a defect.
Easy to get right once you know them:
- Ordering the wrong drivetrain variant (FWD Q5EY vs AWD Q5EZ).
- Using incorrect fluid (such as standard Honda ATF-DW1 or generic multi-vehicle fluids) instead of Honda ATF Type 3.1.
- Skipping the TCM software update and adaptive relearn procedure, leading to immediate harsh shifting and false warranty claims.
- Improper torque converter seating resulting in a cracked pump during installation.
- Skipping the transmission cooler flush, which recirculates debris from the failed unit and voids the warranty.
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:
🔎 Recommended at install: Inspect or replace the transmission warmer/cooler assembly during a swap to prevent coolant and ATF cross-contamination.
🔎 Recommended at install: Update the TCM software with an improved version.
🔎 Recommended at install: Update the ECU/TCM software and perform a triple transmission fluid flush.
🔎 Recommended at install: Replace torn transmission end cover sealing gasket.
🔎 Recommended at install: TCM/PCM calibration updates; subject of Moore v. Honda Class Action.

Policies, in plain English.
Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- 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
120-Day Warranty
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
- Warranty covers defects — not installation errors, misuse, or damage after installation
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
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- 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.
