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 passenger-side B-pillar plate matches TR580DD1BA or TR580DD1AA.
- Confirm the vehicle has the 2.0L engine (Base or Premium trims) and is not a 2.5L model.
- Check the color of the current CVT fluid (should be blue CVTF-III).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Heavy-duty transmission jack
- Engine support bar/brace
- Bi-directional OBD2 scan tool (Subaru Select Monitor SSM4, Autel MaxiSYS, or Launch X431)
- Fluid transfer pump
- Torque converter alignment tool
Budget for these consumables at install:
- Subaru Certified CVTF-III (Blue/Opaque fluid, OEM Part Number: K0415Y0700) - 10.8 to 13.0 Quarts
- Subaru Extra MT 75W-90 or GL-5 spec 75W-90 gear oil (for front differential) - 1.2 to 1.4 Quarts
- Torque Converter Seal (OEM Part Number: 806730100)
- Axle Seals
- High-quality RTV silicone (ThreeBond 1217H or equivalent)
- Cooler Line Flush Agent
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn / AT Learning Mode
sources differ: Arm 1 states dealer tool is required to trigger AT Learning Mode, while Arm 2 states high-end aftermarket scan tools can perform it but dealer-level SSM is recommended. Cautious value selected: dealer tool recommended to ensure all learning procedures complete correctly.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Must click and drop into place three distinct times. If not fully seated, bolting the bellhousing will crack the oil pump housing.
- The Two Plugs Mix-Up: Do not confuse the front differential cavity with the CVT fluid cavity. Draining one and overfilling the other will destroy the unit.
- Precise Fluid Level Check: Must be checked with engine running, vehicle level, and fluid temperature strictly between 95°F and 113°F (35°C to 45°C).
- Bellhousing Dowel Alignment: Ensure alignment dowel pins are not doubled up in the same hole, which will crack the aluminum bellhousing.
- Do Not Use a Power Flush Machine: Pressurized flushing can dislodge debris and clog sensitive valve body passages.
Easy to get right once you know them:
- Ordering the wrong engine-size variant (2.5L instead of 2.0L) which has mismatched final drive ratios.
- Using aftermarket or incorrect CVT fluid instead of genuine Subaru CVTF-III (Blue).
- Failing to perform the TCM adaptive relearn after installation.
- Forgetting to flush the CVT cooler lines, introducing debris from the failed unit into the replacement.
- Assuming 'Lifetime Fluid' means the replacement unit does not need to be filled upon installation.

Researched from factory recalls, TSBs and OEM service data (reference unit 400-11824-5017078). 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.
