Subaru TR580DHMAA Transmission Specifications

The TR580 belongs to Subaru’s Lineartronic continuously variable transmission family.

Unlike a conventional automatic transmission with fixed forward gears, the TR580 continuously adjusts its operating ratio according to vehicle speed, throttle position, and engine load.

As a result, the CVT can keep the FB25 engine within an efficient operating range while providing smooth acceleration.

Technical Specifications

Transmission Code: TR580DHMAA
Transmission Type: Lineartronic CVT
Engine Application: 2.5L FB25
Engine Configuration: Naturally Aspirated 4-Cylinder Boxer
Drivetrain: AWD
Final Drive: 3.70
Condition: Used OEM/JDM
Origin: Japan

Most importantly, this transmission uses a 3.70 final-drive configuration. Always confirm the matching drivetrain ratio before installation.

Why the 3.70 Final Drive Matters

Subaru’s AWD system depends on correctly matched drivetrain gearing.

This TR580DHMAA uses a 3.70 final-drive ratio. Therefore, the rear differential must use the correct compatible ratio.

Do not assume another TR580 transmission will work simply because the case looks similar.

Different Subaru CVTs can use different:

• Final-drive ratios
• Valve bodies
• Sensors
• Electrical connectors
• Internal calibrations
• Transmission cases
• Mounting components

Consequently, installing an incorrectly matched transmission can create AWD binding, abnormal drivetrain operation, or component damage.

Always verify the complete transmission configuration before installation.

Vehicle Compatibility

This TR580DHMAA targets compatible:

2011 Subaru Forester 2.5L

Compatible applications use:

• 2.5L FB25 engine
• Naturally aspirated configuration
• AWD
• Lineartronic CVT
• Matching 3.70 final drive

2012 Subaru Forester 2.5L

Compatible 2012 Forester applications may use the same TR580DHMAA configuration.

However, compare the original transmission code and final-drive ratio before ordering.

2013 Subaru Forester 2.5L

This JDM CVT also targets compatible 2013 Forester 2.5L AWD applications with the matching TR580DHMAA configuration.

Again, verify the complete transmission code rather than purchasing only by model year.

FB25 Engine Application

This transmission pairs with compatible 2.5L FB25 naturally aspirated Forester applications.

The FB25 is Subaru’s chain-driven DOHC 2.5L boxer engine used in this generation of Forester.

Do not confuse this transmission with a turbocharged Forester XT transmission.

Turbo applications can use different CVT specifications, fluid requirements, final-drive configurations, and control strategies.

Therefore, engine configuration remains an important part of fitment verification.

TR580DHMAA vs. Other TR580 Codes

Subaru transmission suffixes matter.

For example, J-Spec also stocks or has stocked:

• TR580DHNAA
• TR580FHEAA
• Other TR580 variants

Although these transmissions belong to the same general family, you should not automatically treat them as interchangeable.

Differences can involve:

• Final-drive ratio
• Model application
• Valve body
• Sensors
• Wiring
• Connectors
• AWD configuration
• Transmission control calibration
• Production revisions

For that reason, compare the entire transmission code before ordering.

JDM-to-USDM Fitment

This transmission came from a Japanese-market drivetrain application.

Although the core TR580DHMAA can serve as a replacement for compatible U.S.-market Foresters, some external differences may exist.

Before installation, place the JDM transmission next to the original USDM unit.

Compare:

• Complete transmission code
• Transmission case
• Bellhousing
• Valve body
• Electrical connectors
• Sensors
• Solenoids
• Wiring connections
• Transmission mounts
• Axle connections
• Driveshaft connection
• Cooler fittings
• Range switch
• Torque converter
• Final-drive configuration

When necessary, transfer compatible external components from the original USDM transmission.

Most importantly, do not force connectors or modify the replacement CVT until you confirm compatibility.

Important CVT Installation Procedure

Correct installation plays a major role in the life of any replacement Subaru CVT.

Contaminated fluid, a restricted cooler, incorrect drivetrain gearing, unresolved electrical problems, or improper setup can damage the replacement transmission.

Therefore, diagnose the original failure before installing the JDM CVT.

Diagnose the Original CVT Failure

First, determine why the original transmission failed.

Possible causes include:

• Internal chain or pulley wear
• Valve-body problems
• Solenoid faults
• Torque-converter problems
• Bearing damage
• Overheating
• Fluid deterioration
• Cooler restrictions
• Sensor faults
• Wiring problems
• Incorrect fluid level
• Transmission control problems

Correcting the original cause helps protect the replacement transmission.

Confirm the Final-Drive Ratio

Before installation, verify that the vehicle uses the correct 3.70 drivetrain configuration.

Do not assume the rear differential is correct simply because the transmission physically fits the vehicle.

An incorrect final-drive match can create drivetrain binding and damage Subaru’s AWD system.

For that reason, confirm the ratio before operating the vehicle.

Flush the Transmission Cooler and Lines

Thoroughly flush the CVT cooler and cooler lines before connecting the replacement transmission.

A failed CVT can circulate metal particles, friction material, and contaminated fluid throughout the cooling circuit.

Consequently, debris left in the cooler can enter the replacement transmission shortly after startup.

Clean the complete cooling circuit before installation.

If a cooler cannot be properly cleaned, replace it.

Do not skip this step.

Use the Correct Subaru CVT Fluid

Use the correct Subaru-specified Lineartronic CVT fluid for this TR580 application.

For naturally aspirated TR580 applications, Subaru’s current service-material guidance identifies Subaru CVTF-II.

Do not use conventional automatic transmission fluid.

Likewise, do not assume every Subaru CVT uses the same fluid.

The correct CVT fluid provides the friction characteristics, lubrication, cooling, and hydraulic operation required by the chain-and-pulley system.

Do Not Reuse Old CVT Fluid

Always use fresh, correct-specification CVT fluid.

Old fluid from the failed transmission may contain:

• Metal particles
• Bearing material
• Friction debris
• Dirt
• Other contamination

As a result, reusing contaminated fluid can shorten the life of the replacement CVT.

Service the Front Differential Separately

The TR580 includes a front differential that uses separate gear oil.

Do not confuse the front differential lubricant with CVT fluid.

Before startup:

• Drain and inspect the front differential oil.
• Refill with the correct Subaru-specified gear lubricant.
• Check the drain and fill plugs.
• Inspect the axle seals for leakage.

Using the wrong fluid in either section can cause serious damage.

Inspect the Torque Converter

Next, inspect the torque converter and confirm compatibility.

Make sure the converter fully seats inside the transmission before installation.

Improper seating can damage the transmission pump during initial startup.

Therefore, never use the bellhousing bolts to pull the transmission forcefully against the engine.

Inspect Accessible Seals

Check accessible transmission seals while the CVT remains outside the vehicle.

Pay particular attention to:

• Axle seals
• Torque-converter seal
• Output areas
• Cooler fittings
• Case sealing surfaces

If you find leakage or deterioration, replace the affected seal before installation.

Doing this work now can prevent unnecessary labor later.

Inspect Engine and Transmission Mounts

Worn drivetrain mounts can cause excessive movement, vibration, or harsh engagement.

Therefore, inspect the engine and transmission mounts before installing the replacement CVT.

Replace any mount that shows cracking, separation, or excessive movement.

Scan the Vehicle Before Removing the Original CVT

Use Subaru-compatible diagnostic equipment before removing the failed transmission.

Record all stored diagnostic trouble codes.

Pay close attention to:

• CVT codes
• Valve-body codes
• Solenoid codes
• AWD codes
• Engine codes
• ABS/VDC codes
• Communication faults

Do not simply clear stored codes.

Instead, diagnose any fault that could affect the replacement transmission.

CVT Relearn and Initialization

After installing a replacement TR580, the vehicle may require CVT initialization, learning, or adaptation procedures.

Depending on the repair, Subaru-compatible diagnostic equipment may be necessary.

Therefore, follow the proper Subaru service procedure after installation.

Do not assume the mechanical installation alone completes the repair.

Verify the CVT Fluid Level Correctly

Correct fluid level remains essential.

After installation, add the proper Subaru CVT fluid according to the factory procedure.

Next, operate the transmission through the required selector positions.

Then verify the fluid level under Subaru’s specified temperature and operating conditions.

Finally, inspect the cooler fittings, axle seals, and transmission case for leaks.

Never guess the CVT fluid level.

Initial Startup Checklist

Before road testing:

• Confirm the 3.70 final-drive configuration.
• Verify CVT fluid level.
• Verify front differential fluid level.
• Check all electrical connectors.
• Inspect cooler-line connections.
• Check axle seals.
• Confirm Drive engagement.
• Confirm Reverse engagement.
• Check for warning lights.
• Listen for abnormal noises.
• Scan for diagnostic trouble codes.
• Inspect for fluid leaks.

If anything appears abnormal, diagnose the problem before driving.

Initial Road Test

Begin with a gentle road test.

During the drive, monitor:

• Drive engagement
• Reverse engagement
• Smooth acceleration
• Engine RPM behavior
• CVT response
• AWD operation
• Transmission temperature
• Shuddering
• Vibration
• Bearing noise
• Warning lights
• Fluid leaks

Avoid aggressive acceleration until you confirm normal operation.

Afterward, scan the vehicle again and inspect the CVT for leaks.

Common Signs of Subaru TR580 CVT Problems

A failing TR580 CVT may produce:

• Shuddering
• Delayed Drive engagement
• Delayed Reverse engagement
• CVT slipping
• RPM flare
• Whining noise
• Bearing noise
• Jerking
• Overheating
• AWD warning lights
• Transmission warning lights
• Fluid leaks
• Diagnostic trouble codes

However, these symptoms do not always mean the complete transmission has failed.

For example, valve-body problems, solenoids, torque-converter faults, incorrect fluid level, wiring problems, or electronic issues can produce similar symptoms.

Therefore, diagnose the vehicle properly before replacing the CVT.
