TR580DD7AA TRANSMISSION CODE

The most important transmission identifier for Item 254596 is:

TR580DD7AA

Do not shorten the product identity to simply:

TR580

Subaru produced many TR580 variants with differences in:

• Final-drive ratio
• Valve body
• Solenoids
• Sensors
• Wiring
• TCM calibration
• AWD transfer control
• Vehicle application
• Production range

Therefore, matching the complete code provides a much stronger starting point for fitment.

Use TR580DD7AA consistently throughout:

• Inventory records

LINEARTRONIC CVT – NOT A 5-SPEED AUTOMATIC

The TR580DD7AA is a:

Subaru Lineartronic Continuously Variable Transmission

It is not a conventional 4-speed, 5-speed, or 6-speed automatic.

Therefore, WooCommerce should show:

Type: Lineartronic CVT

Do not list:

Gears: 5

as though the CVT has five fixed mechanical gears.

The transmission continuously varies its operating ratio. Applicable driver-controlled modes may simulate stepped ratios, but those should not be described as conventional fixed gears.

FB20 2.0L ENGINE APPLICATION

This transmission targets compatible Subaru vehicles equipped with the:

FB20 2.0L DOHC Naturally Aspirated Boxer Engine

The FB20 identification should be included prominently because it provides stronger search and fitment relevance than simply saying:

Subaru 2.0L

However, engine code alone is not sufficient.

For accurate fitment, verify:

FB20 + TR580DD7AA + AWD + 3.70 Final Drive

2012–2013 SUBARU IMPREZA APPLICATION

Primary applications include compatible:

• 2012 Subaru Impreza 2.0L FB20 AWD CVT
• 2013 Subaru Impreza 2.0L FB20 AWD CVT

Before purchasing, verify the original transmission identification.

Do not assume that every FB20 Impreza CVT uses the same TR580 code.

Subaru used multiple TR580 variants across different years and markets.

2013 SUBARU XV CROSSTREK APPLICATION

This TR580DD7AA also targets compatible:

2013 Subaru XV Crosstrek 2.0L FB20 AWD

models equipped with Lineartronic CVT.

The 2013 XV Crosstrek CVT uses a:

3.70 final-drive ratio

which is an important fitment specification.

Always verify the transmission identification and rear differential ratio before installation.

3.70 FINAL DRIVE RATIO

The verified final-drive ratio for this application is:

3.70

This specification is extremely important on a Subaru AWD vehicle.

Use:

TR580DD7AA + 3.70 Final Drive + Matching 3.70 Rear Differential

Do not install a transmission with a different front final-drive ratio against an incompatible rear differential.

An incorrect front-to-rear ratio can cause drivetrain binding and potentially damage:

• CVT
• Transfer section
• Rear differential
• Driveshaft
• Axles
• Tires

MATCHING REAR DIFFERENTIAL REQUIRED

Before installation, verify that the vehicle has the correct:

3.70 rear differential ratio

to match the transmission.

Never assume the rear differential is correct merely because the vehicle uses an FB20 engine.

Check:

• Original transmission code
• Original final-drive ratio
• Rear differential identification
• Rear differential ratio
• Tire size
• Tire circumference

Subaru AWD systems depend on correct front-to-rear drivetrain matching.

AWD CONFIGURATION

The TR580DD7AA is an:

AWD Lineartronic CVT

for the applicable Subaru vehicles.

Do not advertise this transmission as FWD.

The unit incorporates Subaru’s AWD transfer system and integrated front differential.

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

JDM-TO-USDM FITMENT

Japanese-market and U.S.-market Subaru transmissions may differ even when they belong to the TR580 family.

Before installation, place the original CVT next to Item 254596 and compare:

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

Transfer compatible original components only when required.

OEM PART NUMBER VERIFICATION

TR580DD7AA has been cross-referenced in international Subaru inventory with OEM number:

31000AJ450

However, the physical Subaru part number on Item 254596 should be photographed and verified before adding 31000AJ450 as an absolute product-data field for this individual unit.

Use the transmission code:

TR580DD7AA

as the primary identifier until the actual part-number label is confirmed.

VALVE BODY VERIFICATION

Different TR580 variants can use different valve-body and electronic configurations.

Before installation, compare:

• Valve body
• Solenoids
• Pressure-control components
• Electrical connectors
• Wiring
• Sensors
• Calibration requirements

Do not automatically transfer the valve body unless the configuration requires it.

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

ELECTRICAL CONNECTORS AND SENSORS

Compare all electrical components with the original transmission.

Inspect:

• Main connector
• Connector pin count
• Speed sensors
• Pressure sensors
• Solenoid connections
• Harness routing
• TCM-related components

The replacement transmission should match the target vehicle’s electronic configuration.

TORQUE CONVERTER

Verify torque-converter inclusion from the actual Item 254596 inventory before promising it as part of the sale.

If included, inspect:

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

Most importantly, fully seat the torque converter before mating the CVT 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 LINEARTRONIC CVT FLUID

Use the Subaru-specified Lineartronic CVT fluid for the exact transmission and vehicle application.

For 2012–2013 Impreza and early XV Crosstrek TR580 applications, the factory-era specification is associated with Subaru’s original CVT Fluid for Lineartronic, rather than conventional ATF.

Do not use:

• Subaru ATF-HP
• Conventional automatic transmission fluid
• Gear oil
• Generic universal ATF
• An unverified universal CVT fluid

Most importantly, verify the factory fluid specification for the exact VIN and transmission before filling the unit.

FRONT DIFFERENTIAL FLUID IS SEPARATE

The front differential and CVT fluid circuits are separate.

Do not fill the front differential with CVT fluid.

Likewise, do not fill the CVT section with differential gear oil.

During installation:

• Drain and inspect the front differential.
• Refill it separately with the correct Subaru-approved gear oil.
• Verify the fill and drain plugs carefully.
• Confirm the correct fluid level before road testing.

Using the wrong fluid in either circuit can cause serious drivetrain damage.

FLUSH THE CVT COOLER AND LINES

Before operating the replacement CVT, thoroughly flush the transmission cooler and cooler lines.

A failed CVT can leave:

• Metal particles
• Bearing material
• Friction debris
• Contaminated CVT fluid
• Sludge

inside the cooling circuit.

Consequently, reconnecting a replacement transmission to contaminated lines can immediately expose it to debris from the failed unit.

Before startup:

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

Do not skip this step.

INSPECT ACCESSIBLE SEALS

While the transmission is outside the vehicle, inspect:

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

Replacing questionable accessible seals before installation can save substantial labor later.

KEEP THE ORIGINAL CVT

Do not discard the original transmission immediately.

Keep it until Item 254596 has been:

• Installed
• Filled
• Initialized
• Relearned
• Heat-cycled
• Road-tested
• Verified for correct operation

The original transmission may still provide compatible:

• Valve body
• Sensors
• Wiring
• Solenoids
• Brackets
• Mounts
• Cooler fittings
• Shift linkage
• External hardware

TCM / CVT RELEARN AND ADAPTATION

After installation, complete the applicable Subaru:

• TCM initialization
• CVT learning
• Relearn
• Adaptation procedures

as required for the vehicle.

Use a Subaru-capable diagnostic scan tool.

Depending on the vehicle and components transferred, procedures may include:

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

Do not assume the transmission is ready for normal operation immediately after installation.

CHECK FOR TCM SOFTWARE UPDATES

Before completing the job, check whether Subaru has released applicable:

• TCM calibration updates
• ECM updates
• CVT service campaigns
• Technical service information

for the target VIN.

Software and calibration differences can affect operation even when the physical transmission fits correctly.

INSTALLATION CHECKLIST

Before installation:

• Confirm 2012–2013 Impreza or 2013 XV Crosstrek application.
• Confirm FB20 2.0L engine.
• Confirm AWD drivetrain.
• Confirm TR580DD7AA transmission code.
• Confirm 3.70 final-drive ratio.
• Confirm matching 3.70 rear differential.
• Verify Subaru part number where available.
• Compare original and replacement transmissions.
• Compare bellhousing.
• Compare torque converter.
• Compare valve body.
• Compare solenoids.
• Compare sensors.
• Compare connectors.
• Compare wiring harness.
• Compare front differential.
• Compare AWD transfer section.
• Compare axle openings.
• Compare cooler fittings.
• Compare mounting brackets.
• Inspect accessible seals.

MULTIPLE HEAT CYCLES

Run several controlled heat cycles after installation.

The CVT fluid level changes with temperature, and the cooler circuit continues filling after startup.

During each cycle:

• Monitor CVT fluid temperature.
• Recheck fluid level using the proper Subaru procedure.
• Inspect cooler connections.
• Inspect axle seals.
• Confirm Reverse and Drive engagement.
• Check for leaks.

Once the CVT fluid level remains stable, proceed with a conservative road test.

INITIAL ROAD TEST

Begin with light throttle.

Monitor:

• Reverse engagement
• Drive engagement
• Initial takeoff
• Acceleration
• CVT ratio changes
• RPM stability
• Torque-converter lockup
• Shudder
• Slipping
• Hesitation
• Abnormal vibration
• AWD binding
• Warning lights
• Transmission noise
• Fluid leaks

After the road test, scan the vehicle again for stored or pending transmission-related diagnostic codes.
