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:
- Verify the transmission code on the white barcode label reads PYKA.
- Check the 5th and 6th digits of the VIN are TC2 (representing AWD chassis).
- Confirm the vehicle has the 2.0L Turbocharged engine (K20C4).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar or hoist
- Subframe adapter and transmission jack
- Professional bidirectional diagnostic scan tool (Honda i-HDS or equivalent)
Budget for these consumables at install:
- Acura/Honda Genuine ATF Type 2.0 (Service fill: 4.5 - 5.1 qts, Dry fill: 9.3 qts)
- External canister transmission filter (OEM Part: 25450-P4V-013) and O-ring (OEM Part: 91305-PN4-003)
- Warmer assembly O-rings (OEM Parts: 25564-5LJ-A01 and 25565-5LJ-A01)
- Axle/driveshaft seals
- Professional-grade transmission cooler line flush solvent
- Acura/Honda HGO-1 Hypoid Gear Oil (approx. 0.45 qts, if reusing transfer assembly)
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn / Reset
A TCM adaptive memory reset is strictly required using a professional-grade scan tool to clear old wear patterns and write new solenoid flow rates. Manual pedal-press resets are unreliable for a physical swap.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Ensure the converter is fully engaged into the fluid pump before bolting to the engine to avoid cracking the pump gear.
- The Level Check Trap: Fluid level must be checked via the side check bolt on a perfectly level surface with the engine warmed up (104°F-113°F) after cycling through all gears.
- Subframe Alignment: Mark alignment points or use alignment pins when lowering the subframe to prevent steering misalignment and tire wear.
- Adaptive Learning Reset: Must clear TCM memory and perform a varied drive cycle post-install to prevent shift shock and internal damage.
Easy to get right once you know them:
- Ordering the FWD version (PYLA) for an AWD vehicle (PYKA).
- Using incorrect or universal fluid instead of Acura Genuine ATF Type 2.0.
- Skipping the transmission cooler line flush, which recirculates debris from the failed unit.
- Skipping the electronic TCM adaptive memory relearn procedure.
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 torque converter lock-up piston for cracks; update vehicle software to prevent future piston stress.
🔎 Recommended at install: Flash vehicle modules (ECM/TCM) with the latest Acura software updates.
🔎 Recommended at install: Replace affected front driveshaft if improperly heat-treated.
🔎 Recommended at install: Perform TCM adaptive learning reset or software update.

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.
