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 ID code on the B-pillar door jamb placard matches TR580DD1AA or TR580DD1BA.
- Verify the engine is a 2.0L naturally aspirated unit via the emissions label under the hood or the 8th digit of the VIN.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar or hoist
- Professional transmission jack
- Torx T-70 bit (for front differential drain)
- 8mm Hex/Allen socket (for front differential fill/check plug)
- OBD-II scan tool with Subaru-specific software
Budget for these consumables at install:
- Genuine Subaru CVTF-II (Part # SOA427V1660) or High-Torque Lineartronic CVT Fluid (HT-CVT) - sources differ on exact spec, confirm with us before install
- 75W-90 Synthetic Gear Lube (API GL-5 spec) for front differential (approx. 1.3 to 1.4 quarts)
- Torque converter seal (front pump seal)
- Axle seals
- Transmission filter and pan gasket
- Dedicated transmission cooler flush solvent
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn (Clear AT Learning Value and execute AT Learning Mode)
A Transmission Control Module (TCM) adaptive relearn is mandatory to calibrate the replacement unit's solenoids and pulleys. Can be performed with SSM4 or advanced aftermarket scan tools (e.g., Autel MaxiSYS, OTOFIX, Launch X431, Xtool).
Pro tips for a smooth first start-up — hand them to whoever does the install:
- CVT vs. Front Differential Fluid Mix-Up: The front differential and CVT are separate chambers. Do not pump gear oil into the CVT ports or vice versa.
- Torque Converter Seating: Ensure the torque converter is fully seated (feeling 2-3 distinct clicks/drops) before bolting to the engine to avoid cracking the oil pump gear.
- Fluid Level Temperature Window: Fluid level must be checked only when fluid temperature is between 95°F and 113°F (35°C to 45°C) with the engine idling and vehicle level.
- Dowel Pin Alignment: Ensure alignment dowels are clean and in place so the transmission slides onto the engine block smoothly.
Easy to get right once you know them:
- Ordering for a 2.5L engine model (Crosstrek Sport/Limited/Wilderness or Impreza RS).
- Reusing the old contaminated torque converter.
- Skipping the TCM adaptive relearn procedure.
- Using generic multi-vehicle CVT fluid instead of Genuine Subaru fluid.
- Failing to flush the transmission cooler lines before installation.
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 existing driveshafts during swap; replace if cracked or if recall has not been performed.
🔎 Recommended at install: Replace valve body with updated design kit (Part # 31825AA055) to resolve codes P2757/P2762 and acceleration shudder.
🔎 Recommended at install: Inspect and repair wiring harness contact with bracket to prevent loss of drive power.
Researched from factory recalls, TSBs and OEM service data (reference unit 400.SU1O25-5427199). Unit-specific details — mileage, condition, warranty, freight — are covered in the checkout interview.
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.
