Subaru Transmissions We Cover

Real transmissions from our warehouse, VIN-matched and ready to ship. Every modern Subaru is AWD except the BRZ — and the Boxer engine + symmetrical AWD platform means Subaru transmissions have a distinctive longitudinal transaxle layout not shared with any other Japanese brand.

TR690 Lineartronic CVT

Outback, Legacy, Tribeca, Ascent (2010+). Subaru's larger CVT — paired with FB25 and EZ36. Highest volume in modern Subaru inventory.

TR580 Lineartronic CVT

Impreza, Forester, Crosstrek (2012+). Compact CVT — paired with FB20 exclusively. Not cross-installable with TR690.

TY75 5-Speed Manual (AWD)

Impreza, Forester, Legacy, Outback (2000s–2010s). Standard AWD 5-speed transaxle — simple, rebuildable, plentiful.

TY856 6-Speed Manual (WRX STI 2008–2021)

WRX STI (2008–2021). Heavy-duty AWD 6-speed with DCCD center differential. High enthusiast demand. NOT interchangeable with 2004–2007 TY750.

4EAT 4-Speed Automatic (AWD)

Legacy, Outback, Forester, Impreza (1990s–2000s). Classic NA-application 4-speed automatic AWD transaxle — proven workhorse.

5EAT 5-Speed Automatic (AWD, turbo)

Outback XT, Legacy GT, Tribeca, WRX (2005–2014). Heavy-duty 5-speed automatic for turbo and EZ30 applications — different torque converter and gearsets than 4EAT.

Aisin TR-6060 6-Speed Manual (BRZ, RWD)

BRZ, Toyota 86, Scion FR-S (2013–2020). RWD-only Aisin 6-speed — Toyota/Subaru JV unit, NOT interchangeable with any AWD Subaru.

TY750 6-Speed Manual (WRX STI 2004–2007)

2004–2007 WRX STI only. Pre-TY856 6-speed with different center diff and gear ratios — collector demand, rebuilder favorite.

TR580H Hybrid CVT

Crosstrek Hybrid (2014–2018). Hybrid CVT with integrated electric motor — year-locked and non-interchangeable with standard TR580.

Phase 1 4EAT 4-Speed (Early 90s)

Early 1990s Legacy, Impreza, Forester first gen. Original 4EAT with Phase 1 mounting — NOT interchangeable with post-2000 Phase 2 units.

Phase 1 5-Speed Manual (Early 90s)

Early 1990s Legacy, Impreza. Classic Phase 1 AWD 5-speed transaxle — restoration-grade, limited supply.

Why Buy a Used Subaru Transmission from Auto Power Source

Subaru transmissions are unlike any other Japanese OEM's. The symmetrical AWD platform and longitudinally-mounted Boxer engine mean Subaru transaxles are their own family — the TR690 and TR580 Lineartronic CVTs, the TY75 5-speed, the TY856 and TY750 STI 6-speeds, the 4EAT and 5EAT automatics all share a distinct architectural DNA with a front differential integrated into the transmission case. That does two things for sourcing: it makes Subaru transmissions non-cross-fittable with any other brand (a Nissan CVT will not fit a Forester), and it means the STI 6-speeds (both TY750 pre-2008 and TY856 2008+) are specifically calibrated to the DCCD center differential and not interchangeable with each other or with any non-STI Subaru manual.

Every Subaru transmission we sell has been pulled from a low-mileage donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse. Each unit went through our six-step inspection — VIN-matching, ASE Shift-Testing through every gear under load, noise & smoke verification, full visual inspection of the case and front differential, multi-angle photography, and palletized shipping. Our ASE-certified technicians pay specific attention to CVT valve-body condition on TR580/TR690, DCCD center-diff function on STI 6-speeds, and torque converter condition on 5EAT turbo applications. Rejected units never reach the buyer.

You pay a fraction of dealer-new pricing for identical Subaru engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get 30 days from delivery to return for any reason — no restocking fees. Up to a 3-year warranty covers you if anything goes wrong after install. Across 100,000+ engines and transmissions shipped, we hold a 0% fitment-related return rate.

Subaru Transmission Buying Guide

Subaru's Boxer + symmetrical AWD layout means transmission fitment is stricter than most brands. Five things to verify before buying a used Subaru transmission:

1. Every modern Subaru is AWD except the BRZ. The BRZ uses the Aisin TR-6060 6-speed manual (shared with Scion FR-S and Toyota 86) — RWD-only, longitudinal, will NOT drop into any WRX, STI, Impreza, Forester, or Outback. Confirm your vehicle is the BRZ before ordering an Aisin TR-6060, and confirm it is NOT the BRZ before ordering any other Subaru unit.
2. CVT variants are engine-displacement-locked. The TR690 Lineartronic CVT pairs with FB25 and EZ36 (larger applications: Outback, Legacy, Ascent, Tribeca). The TR580 pairs with FB20 exclusively (compact applications: Impreza, Forester, Crosstrek). These are NOT interchangeable — the case and torque converter are sized to the engine. The TR580H Hybrid unit is additionally locked to the Crosstrek Hybrid platform 2014–2018.
3. STI 6-speed TY750 and TY856 are NOT interchangeable. The 2004–2007 WRX STI shipped with the TY750; the 2008–2021 STI shipped with the TY856. Both are AWD with DCCD center differentials, but gear ratios, center-diff calibration, and mounting differ. Sourcing the wrong generation results in incorrect ratios, DCCD control faults, and mounting incompatibilities.
4. Turbo vs NA calibration matters for automatics. The 5EAT 5-speed automatic is the turbo/high-torque unit (Outback XT, Legacy GT, WRX auto, EZ30 Tribeca) — different torque converter, different valve body, different gearsets than the 4EAT. Sourcing a 4EAT for a turbo application will result in slippage and premature failure.
5. Phase 1 (early 1990s) is a different architecture. Original Phase 1 Legacy, Impreza, and Forester (early 1990s) used a different transmission mounting and case design. Post-2000 Phase 2 units will NOT bolt to a Phase 1 chassis. Restoration builds should verify Phase 1 vs Phase 2 before ordering.

Our ASE-certified technicians verify every one of these points against your VIN before any transmission ships.
