JDM 2013–2016 Subaru BRZ / Scion FR-S / Toyota GT86 6-Speed Manual RWD Transmission – FA20 2.0L

Replace your grinding, noisy, damaged, or failed gearbox with a low-mileage JDM Subaru BRZ / Scion FR-S / Toyota GT86 6-speed manual transmission from J-Spec Auto Sports.

This genuine OEM Japanese-market 6MT targets compatible 2013–2016 Subaru BRZ, Scion FR-S, and Toyota GT86 models equipped with the naturally aspirated 2.0L FA20 engine and rear-wheel drive.

The current inventory unit was imported directly from Japan with approximately 60,000 miles. In addition, J-Spec Auto Sports provides actual product photos so buyers can compare the transmission with their original gearbox before purchase.

Subaru’s factory specifications confirm that the BRZ 6-speed manual uses six forward gears with a 4.100 final-drive ratio.

Because multiple versions of the BRZ/86 drivetrain exist across different production years, always verify the complete transmission configuration before installation.

BRZ / FR-S / GT86 6-Speed Manual Transmission Specifications

The first-generation BRZ, FR-S, and GT86 share the same basic rear-wheel-drive sports-car platform.

Subaru and Toyota paired the platform with the naturally aspirated 2.0L FA20 / 4U-GSE boxer engine and a close-ratio 6-speed manual gearbox.

Factory 6-Speed Manual Gear Ratios

• 1st Gear: 3.626
• 2nd Gear: 2.188
• 3rd Gear: 1.541
• 4th Gear: 1.213
• 5th Gear: 1.000
• 6th Gear: 0.767
• Reverse: 3.437
• Final Drive: 4.100

Subaru’s official 2016 BRZ specifications confirm these ratios and the 4.10 final drive.

The relatively close gear spacing supports responsive acceleration and keeps the FA20 within its useful RPM range during spirited driving.

Important: This Is a 6-Speed Manual Transmission

This product is a 6-speed manual gearbox, not an automatic transmission.

The manual transmission uses a conventional clutch and driver-operated gear selection.

Therefore, customers should verify:

• Clutch configuration
• Flywheel
• Release bearing
• Clutch fork
• Slave cylinder
• Shifter assembly
• Driveshaft
• Transmission mount
• Sensors and switches

before installation.

2013–2016 Toyota GT86

Compatible Japanese and international Toyota GT86 applications use the same basic FA20/4U-GSE rear-wheel-drive platform.

However, always compare the replacement gearbox with the original before installation.

Important 2013–2016 vs. 2017+ Difference

I recommend keeping this product focused on 2013–2016.

Later 2017+ BRZ and Toyota 86 manual drivetrain configurations received revisions, and replacement-transmission references distinguish those later units from the earlier 2013–2016 version.

Therefore, do not automatically advertise this specific transmission as fitting 2017+ vehicles.

Keeping the listing tightly focused on 2013–2016 also helps prevent it from competing with your separate 2013–2017 transmission listing.

FA20 2.0L Engine Application

This transmission pairs with compatible naturally aspirated FA20 2.0L boxer-engine applications.

Toyota identifies its version of the engine as the 4U-GSE, while Subaru uses the FA20 designation.

Because the BRZ, FR-S, and GT86 share this drivetrain architecture, customers often search using either engine name.

However, engine compatibility alone does not guarantee direct transmission interchange.

Always verify the gearbox configuration before installation.

ZN6 6MT Product Identification

The current J-Spec product page uses:

Product Code: ZN6 6MT

This is a useful platform-based identifier because ZN6 refers to the Toyota 86/GT86 chassis family.

However, if the actual Subaru transmission identification label or OEM part number remains visible, I recommend adding that specific number to the Details section as well.

A specific transmission number gives buyers and search engines stronger fitment information than “ZN6 6MT” alone.

Transmission Identification

Replacement references commonly identify the early BRZ/FR-S manual transmission as an Aisin AZ6-family 6-speed gearbox, with Subaru/Toyota-specific configurations.

Do not assume another AZ6-family gearbox from a Mazda, Nissan, Lexus, or other vehicle will interchange.

Different applications can use different:

• Bellhousings
• Tail housings
• Shifter positions
• Gear ratios
• Mounting locations
• Driveshaft connections
• Sensors
• Internal components

Therefore, always source the gearbox by complete vehicle application.

Factory 4.10 Final Drive

The factory manual drivetrain uses a 4.10 final drive.

Subaru confirms a 4.100 final-drive ratio for the 2016 BRZ 6-speed manual.

This ratio refers to the rear differential gearing.

Therefore, if this product includes a matching rear differential, it should also be identified as 4.10.

Important: Confirm Whether the Rear Differential Is Included

This specific Item ID 44768 page does not currently state that the rear differential comes with the transmission. It only lists Final Drive: 4.1 in the Details section.

Meanwhile, your separate Item ID 411 product specifically says that its package includes the 6-speed transmission and 4.1 rear differential.

Therefore, do not copy the “rear differential included” claim from Item 411 onto Item 44768 unless the actual inventory photos confirm it.

For Item 44768, I recommend:

Factory Final Drive: 4.10

instead of:

Includes 4.10 Rear Differential

unless the differential is physically part of the sale.

What Is Included?

The sale includes the actual 6-speed manual transmission represented in the current product photographs.

Depending on the components shown with the individual inventory unit, attached parts may include:

• 6-speed manual transmission assembly
• Transmission housing
• Internal geartrain
• Shifter-related components when pictured
• Sensors or switches that remain attached
• Brackets when pictured

Do not automatically assume the sale includes:

• Rear differential
• Clutch
• Flywheel
• Driveshaft
• Axles
• Starter
• Slave cylinder
• Shifter assembly
• Mounts

unless the actual photographs or product Details specifically state otherwise.

JDM-to-USDM Fitment

This transmission came from a Japanese-market drivetrain application.

Although the basic gearbox can work with compatible U.S.-market BRZ and FR-S applications, always compare the replacement transmission with the original unit.

Check:

• Transmission case
• Bellhousing
• Transmission identification
• Shifter configuration
• Reverse-light switch
• Neutral switch
• Sensors
• Electrical connectors
• Transmission mount
• Driveshaft flange
• Clutch release components
• Starter location

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

Most importantly, do not modify the gearbox before confirming fitment.

Recommended Maintenance Before Installation

A manual transmission replacement provides an excellent opportunity to service several wear items.

Doing this work while the transmission remains outside the vehicle can save substantial labor later.

Replace the Transmission Fluid

First, drain the existing transmission lubricant.

Next, inspect the drained oil for:

• Metal particles
• Bearing debris
• Discoloration
• Water contamination
• Unusual material

Then refill the gearbox with the correct manufacturer-specified manual transmission lubricant.

Fresh fluid provides a known service baseline for the replacement gearbox.

Inspect the Clutch

Since the transmission is already removed, inspect the complete clutch assembly.

Check:

• Clutch disc
• Pressure plate
• Flywheel
• Release bearing
• Pilot bearing
• Clutch fork
• Pivot
• Slave cylinder

If the clutch has substantial mileage or shows wear, replacing it now can prevent another transmission removal later.

Inspect the Flywheel

Examine the flywheel surface carefully.

Look for:

• Heat spots
• Cracks
• Grooves
• Excessive wear
• Warping
• Damaged ring-gear teeth

Resurface or replace the flywheel according to the clutch manufacturer’s requirements.

Inspect the Release Bearing

A worn release bearing can produce noise whenever the clutch pedal is depressed.

Therefore, replace an old or questionable bearing while the transmission is already out.

This inexpensive step can save considerable labor later.

Inspect the Pilot Bearing

Check the pilot bearing or pilot support components.

A damaged pilot bearing can cause:

• Noise
• Difficult shifting
• Input-shaft vibration
• Premature clutch wear

Replace worn parts before installation.

Inspect Transmission Seals

Check accessible seals before installing the replacement gearbox.

Pay close attention to:

• Input shaft area
• Output shaft seal
• Shifter seals
• Case sealing surfaces

Replacing a leaking seal now is significantly easier than removing the gearbox again later.

Inspect the Rear Main Seal

Transmission removal exposes the engine rear-main-seal area.

Therefore, inspect the engine for oil leakage before reinstalling the gearbox.

If the rear main seal leaks, address the problem while access remains easy.

Inspect the Transmission Mount

A worn transmission mount can cause:

• Drivetrain movement
• Clunking
• Vibration
• Poor shift feel
• Excessive driveline shock

Inspect the mount and related hardware before installation.

Inspect the Driveshaft

Check the driveshaft and related connection points.

Look for:

• Excessive play
• Damaged splines
• Worn joints
• Damaged flange surfaces
• Missing hardware

A worn driveline component can create vibration that may incorrectly appear to be a transmission problem.

Inspect the Rear Differential

If you plan to reuse the existing rear differential, inspect it before road testing.

Check:

• Gear oil condition
• Input flange
• Axle seals
• Bearings
• Excessive backlash
• Abnormal noise
• Fluid leaks

For a stock 2013–2016 manual drivetrain, verify the correct 4.10 final-drive configuration.

Installation Checklist

Before installation:

• Confirm vehicle year.
• Verify 6-speed manual configuration.
• Compare the JDM and original transmissions.
• Confirm transmission identification.
• Inspect clutch disc.
• Inspect pressure plate.
• Inspect flywheel.
• Replace worn release bearing.
• Inspect pilot bearing.
• Check transmission seals.
• Inspect rear main seal.
• Inspect transmission mount.
• Verify driveshaft fitment.
• Confirm shifter configuration.
• Replace transmission fluid.
• Inspect the rear differential.
• Verify all electrical switches.
• Torque all fasteners correctly.

Initial Startup and Road Test

Before driving, operate the clutch and shifter while the vehicle remains stationary.

Confirm smooth engagement into:

• Reverse
• First
• Second
• Third
• Fourth
• Fifth
• Sixth

Next, begin with a gentle road test.

Monitor:

• Clutch engagement
• Shift quality
• Gear noise
• Transmission whine
• Driveshaft vibration
• Differential noise
• Fluid leaks
• Gear pop-out

Avoid aggressive driving until you confirm normal operation.

Afterward, inspect the gearbox again for leaks.

Common Signs of BRZ / FR-S Manual Transmission Problems

A worn manual transmission may produce:

• Gear grinding
• Difficult shifting
• Synchronizer problems
• Gear pop-out
• Transmission whine
• Bearing noise
• Fluid leaks
• Shifter vibration
• Abnormal drivetrain noise

However, not every shifting complaint means the transmission itself has failed.

For example, worn clutch components, shifter bushings, transmission mounts, or incorrect lubricant can create similar symptoms.

Therefore, diagnose the complete drivetrain before replacing the gearbox.
