TR580FHEAA TRANSMISSION CODE

The most important identifier for Item 254615 is:

TR580FHEAA

The exact serial identification is:

TR580FHEAA 061594

Use the complete TR580FHEAA code throughout:

• Product title
• H1
• Short description
• Product specifications
• Image ALT text
• Image titles
• FAQ
• Structured data
• Inventory records

Do not identify this transmission as:

TR580DHACA

The physical product data on Item 254615 identifies it as:

TR580FHEAA

That should be the primary code everywhere on the page.

TR580FHEAA VS. TR580DHACA

TR580FHEAA and TR580DHACA are different Subaru transmission codes.

Do not combine them on the same product page.

Although both belong to Subaru’s TR580 Lineartronic family, differences may involve:

• Final-drive ratio
• Valve body
• Sensors
• Solenoids
• Electrical connectors
• Internal calibration
• AWD configuration
• Vehicle application
• Production specification

Therefore:

TR580FHEAA does not automatically equal TR580DHACA.

Item 254615 should be indexed and marketed using its actual physical code:

TR580FHEAA

LINEARTRONIC CVT – NOT A 5-SPEED AUTOMATIC

The TR580FHEAA is a:

Subaru Lineartronic Continuously Variable Transmission

It is not a conventional 5-speed automatic.

Therefore, remove:

Gears: 5

from the WooCommerce product specifications.

A CVT continuously varies its operating ratio rather than shifting through five fixed mechanical forward gears.

Recommended product data:

Type: Lineartronic CVT

Gears: CVT / Variable Ratio

Drivetrain: AWD

FB25 2.5L ENGINE APPLICATION

This transmission targets compatible vehicles equipped with Subaru’s:

FB25 2.5L Naturally Aspirated Boxer Engine

Use the complete:

FB25

engine code throughout the page.

This provides a stronger product identity than simply:

Subaru 2.5L transmission

However, FB25 alone does not establish transmission interchange.

Always verify:

FB25 + TR580FHEAA + AWD + 3.70 Final Drive

2013 SUBARU LEGACY 2.5L

Item 254615 targets compatible:

2013 Subaru Legacy 2.5i AWD

applications using the correct TR580FHEAA configuration.

Verify:

• FB25 2.5L engine
• TR580FHEAA transmission configuration
• AWD
• 3.70 final drive
• Rear differential ratio
• Valve body
• Sensors
• Electrical connectors
• Mounting configuration

2014 SUBARU LEGACY 2.5L

Item 254615 also targets compatible:

2014 Subaru Legacy 2.5i AWD

applications after complete code verification.

Confirm:

• Original transmission code
• FB25 engine
• AWD configuration
• 3.70 final drive
• Rear differential
• Electrical connectors
• Valve body
• Sensors
• Solenoids
• Mounting configuration

Do not rely solely on model year.

IMPORTANT – REMOVE 2015–2017 FROM THIS PAGE

Do not automatically extend Item 254615 to:

2015–2017 Subaru Legacy

simply because those vehicles also use a 2.5L engine and Lineartronic CVT.

Subaru changed drivetrain specifications across generations and model years.

Therefore, this individual TR580FHEAA listing should remain tightly targeted to the verified:

2013–2014 Subaru Legacy 2.5L AWD

application unless later fitment is independently confirmed for this exact transmission configuration.

IMPORTANT – REMOVE OUTBACK FROM THE PRIMARY FITMENT

Do not automatically advertise Item 254615 as a direct:

2013–2014 Subaru Outback

replacement.

Legacy and Outback vehicles can use different drivetrain ratios even when they share:

• FB25 engine
• TR580 transmission family
• AWD
• Similar model years

The complete transmission code and final-drive ratio must match.

Therefore, keep this page focused on the verified:

Legacy + TR580FHEAA + 3.70

relationship.

3.70 FINAL DRIVE

The verified application final-drive ratio for this transmission is:

3.70

This specification is one of the most important fields on the product page.

For Subaru AWD applications, the front and rear drivetrain ratios must be compatible.

The correct product identity is:

TR580FHEAA + 3.70 Final Drive + Matching Rear Differential

Do not install a different-ratio transmission simply because it physically bolts to the FB25 engine.

MATCHING REAR DIFFERENTIAL REQUIRED

Before installation, verify the vehicle’s rear differential ratio.

The replacement drivetrain must maintain compatible front-to-rear gearing.

Check:

• Transmission code
• Transmission final drive
• Rear differential identification
• Rear differential ratio
• AWD configuration
• Tire circumference

Operating an AWD Subaru with incompatible front and rear ratios may cause:

• Drivetrain binding
• Transfer-system stress
• Excessive heat
• Front differential damage
• Rear differential damage
• CVT damage

AWD CONFIGURATION

The TR580FHEAA is an:

AWD Lineartronic CVT

for the applicable Subaru Legacy platform.

The transmission contains the integrated front differential and AWD transfer components.

Therefore, drivetrain verification is just as important as engine compatibility.

TR580FHEAA VS. TR580FHDAA

TR580FHEAA and TR580FHDAA should not automatically be treated as the same transmission.

Although both belong to the TR580 family and can appear in related Subaru Legacy applications, suffix differences can identify application-specific variations.

Before substituting one for the other, verify:

• Complete transmission code
• Subaru part number
• Model year
• Final-drive ratio
• Valve body
• Sensors
• Solenoids
• Electrical connectors
• Wiring
• Case configuration
• Mounting

Never purchase a Subaru CVT based only on:

TR580

JDM-TO-USDM FITMENT

Japanese-market and U.S.-market Subaru transmissions may have differences even when they belong to the same basic transmission family.

Before installation, place Item 254615 next to the original transmission.

Compare:

• Complete transmission code
• Subaru OEM part number
• Transmission case
• Bellhousing
• Torque converter
• Valve body
• Solenoids
• Sensors
• Electrical connectors
• Wiring harness
• Front differential
• AWD transfer section
• Axle openings
• Cooler fittings
• Transmission mounts
• External brackets
• Shift linkage

Transfer compatible original components only when required and verified.

VALVE BODY VERIFICATION

TR580 variants can use different valve-body configurations.

Before installation, compare:

• Valve-body part number
• Solenoid configuration
• Pressure-control components
• Electrical connectors
• Harness
• Sensors

Do not automatically transfer the valve body.

Likewise, do not assume another TR580 valve body is interchangeable simply because the transmission case appears similar.

ELECTRICAL CONNECTORS AND SENSORS

Compare:

• Main transmission connector
• Connector shape
• Connector pin count
• Harness routing
• Speed sensors
• Pressure sensors
• Temperature sensors
• Solenoid connectors

Electronic compatibility is essential for correct CVT operation.

TORQUE CONVERTER

Verify torque-converter inclusion from the actual Item 254615 inventory photographs before advertising it as included.

If supplied, inspect:

• Converter hub
• Splines
• Pilot
• Seal surface
• Mounting points
• Overall physical condition

Most importantly, fully seat the torque converter before mating the transmission to the engine.

Never use bellhousing bolts to pull the transmission against the engine.

Improper torque-converter installation can damage the transmission pump.

USE THE CORRECT SUBARU CVT FLUID

Use the Subaru-specified CVT fluid for the exact TR580FHEAA and target vehicle application.

For applicable later TR580 service procedures, Subaru CVTF-II may be specified.

However, verify the correct fluid specification by:

• VIN
• Transmission code
• Subaru service information
• Applicable service bulletin

before filling the transmission.

Do not use:

• Conventional ATF
• Subaru ATF-HP
• Gear oil
• Generic universal ATF
• Unverified universal CVT fluid

FRONT DIFFERENTIAL FLUID IS SEPARATE

The front differential and CVT hydraulic circuits use separate lubricants.

Do not put CVT fluid in the front differential.

Likewise, never put differential gear oil into the CVT.

During installation:

• Drain and inspect the front differential.
• Inspect for contamination.
• Refill with the correct Subaru-approved gear oil.
• Verify the proper fluid level.
• Inspect axle seals.

FLUSH THE CVT COOLER AND LINES

Before operating Item 254615, thoroughly flush the transmission cooler and cooler lines.

A failed CVT may leave:

• Metal particles

• Contaminated CVT fluid
• Sludge

inside the cooler circuit.

Connecting the replacement transmission to contaminated lines can immediately expose the replacement unit to debris.

Therefore:

• Flush the CVT cooler.
• Flush cooler lines.
• Confirm unrestricted flow.
• Remove contaminated fluid.
• Replace a cooler that cannot be properly cleaned.

INSPECT ACCESSIBLE SEALS

While the transmission is outside the vehicle, inspect:

• Torque-converter / input seal
• Front axle seals
• Cooler-line seals
• Selector-shaft seal
• Case sealing surfaces

Replace questionable accessible seals before installation.

KEEP THE ORIGINAL TRANSMISSION

Do not discard the original CVT until Item 254615 has been:

• Brackets
• Mounts
• Cooler fittings
• Shift linkage
• External hardware

TCM INITIALIZATION / CVT RELEARN

After installation, perform all applicable Subaru:

• TCM initialization
• CVT learning
• Relearn
• Adaptation procedures

Use a Subaru-capable diagnostic scan tool whenever possible.

Depending on the vehicle, the process may include:

• Clearing CVT DTCs
• TCM memory reset
• CVT learning
• Calibration
• Road-learning procedure
• Software-update verification

Do not assume the CVT is ready for unrestricted driving immediately after installation.

CHECK FOR ECM / TCM SOFTWARE UPDATES

Before completing the repair, check the target VIN for applicable:

• TCM software updates
• ECM updates
• Subaru Technical Service Bulletins
• CVT service procedures
• Campaigns

Software differences can affect operation even when the mechanical transmission fits.

MATCH ALL FOUR TIRES

Subaru AWD systems are sensitive to differences in tire circumference.

Before road testing, verify:

• Tire size
• Tread depth
• Tire circumference
• Inflation pressure

All four tires should be closely matched according to Subaru specifications.
