What Is an MFKA Transmission?

MFKA identifies a Honda automatic transmission used with certain K24-series 2.4L front-wheel-drive applications.

This transmission features a conventional 5-speed automatic transaxle design with a torque converter.

For Google, Bing, and AI search engines, the primary product relationship should be:

Honda Accord / Acura TSX → K24-Series 2.4L → MFKA → 5-Speed Automatic → FWD

Using this structure provides stronger technical context than simply calling the product a “K24 transmission.”

Honda Accord Compatibility

This MFKA transmission targets compatible:

2003 Honda Accord 2.4L

2004 Honda Accord 2.4L

2005 Honda Accord 2.4L

2006 Honda Accord 2.4L

2007 Honda Accord 2.4L

The live J-Spec Applications field specifically lists 2003–2007 Honda Accord 2.4L.

However, compatibility should still be verified using the original transmission identification and physical configuration.

Before ordering, compare:

• Transmission code
• VIN
• Bellhousing
• Electrical connectors
• Sensors
• Solenoids
• Torque converter
• Mounts
• Axle openings
• Cooler fittings

Acura TSX Compatibility

This MFKA transmission also targets compatible:

2004 Acura TSX 2.4L

2005 Acura TSX 2.4L

2006 Acura TSX 2.4L

2007 Acura TSX 2.4L

2008 Acura TSX 2.4L

The live Applications field correctly identifies the TSX range as 2004–2008 Acura TSX 2.4L.

Therefore, the current page title and description should not say 2003–2007 Acura TSX.

Instead, use:

2004–2008 Acura TSX 2.4L

throughout the product page.

Important: K24-Series Engine Wording

The current page uses K24A 2.4L as a general application description.

For a page covering both Accord and TSX applications, I recommend using:

K24-Series 2.4L

as the primary engine-family designation.

For TSX-specific search terms, you can additionally reference:

K24A2 2.4L

This approach gives you useful K24A/K24A2 keyword coverage without incorrectly suggesting every Accord application uses exactly the same K24 engine variant.

MFKA vs. MGTA vs. MCTA

Honda used several automatic transmission codes across related K24-powered vehicles.

Consequently, do not automatically assume:

MFKA = MGTA = MCTA

A transmission may appear physically similar while differences exist in:

• Internal gearing
• Final-drive configuration
• Valve body
• Shift solenoids
• Pressure-control solenoids
• Sensors
• Electrical connectors
• Torque converter
• Case revisions
• Electronic calibration

Always compare the replacement unit with the vehicle’s original transmission before installation.

5-Speed Automatic Transmission

The live listing correctly identifies this MFKA as:

Type: Automatic
Gears: 5

Keep both specifications.

This is a conventional 5-speed automatic transmission, not a CVT.

Front-Wheel Drive

This MFKA uses a front-wheel-drive configuration. The current description already identifies the drivetrain as FWD.

I recommend adding:

Drivetrain: FWD

to the structured Details section so customers and search engines can identify it immediately.

JDM-to-USDM Fitment

Because this transmission came from a Japanese-market application, some external components may differ from the original U.S.-market transmission.

Before installation, place the replacement MFKA beside the original transmission and compare both units carefully.

Check:

• Complete transmission code
• Bellhousing
• Transmission case
• Torque converter
• Electrical connectors
• Shift solenoids
• Pressure-control solenoids
• Speed sensors
• Pressure switches
• Range switch
• Cooler fittings
• Transmission mounts
• Mounting brackets
• Axle openings
• Wiring connections

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

Most importantly, keep the original transmission and all external components until the replacement unit has been successfully installed and road-tested.

What Is Included?

The sale includes the actual MFKA automatic transmission shown in the J-Spec Auto Sports product photographs.

Depending on what remains attached to this individual unit, the transmission may include:

• MFKA 5-speed automatic transmission assembly
• Transmission case
• Internal transmission components
• Valve-body components
• Factory sensors that remain attached
• Solenoids that remain attached
• Electrical connectors
• Torque converter when shown or specifically stated
• External brackets when pictured

Only components shown in the actual product photos or specifically listed should be considered included.

Actual Product Photos

Use the actual product photographs to compare the replacement transmission with the original unit.

Pay particular attention to:

• MFKA identification
• Serial number
• Bellhousing
• Torque converter
• Electrical connectors
• Sensors
• Solenoids
• Axle openings
• Mounting locations
• Cooler fittings
• Case configuration

Actual inventory photography also helps customers verify exactly which physical transmission they are purchasing.

RECOMMENDED INSTALLATION PROCEDURE

Diagnose the Original Transmission Failure

Before installing the replacement MFKA, determine why the original transmission failed.

Possible causes include:

• Internal clutch wear
• Valve-body problems
• Shift-solenoid faults
• Pressure-control problems
• Torque-converter failure
• Overheating
• Low ATF
• Contaminated ATF
• Restricted cooler
• Wiring faults
• Sensor problems
• Worn engine or transmission mounts

Correcting the underlying problem can help protect the replacement transmission.

Flush the Transmission Cooler and Lines

Thoroughly clean the transmission cooler and cooler lines before installing the replacement unit.

A failed automatic transmission can circulate:

• Metal particles
• Clutch material
• Friction debris
• Contaminated ATF

As a result, contamination left inside the cooling system can immediately enter the replacement transmission.

Flush the complete cooling circuit. If the cooler cannot be properly cleaned, replace it.

Do not skip this step.

Use the Correct Honda / Acura ATF

Fill the transmission with the correct Honda/Acura automatic transmission fluid specified for the vehicle and transmission application.

For current service applications, verify the use of:

Honda / Acura ATF DW-1

Do not use CVT fluid or gear oil in this transmission.

Furthermore, avoid using an unspecified universal ATF without confirming that it meets the correct Honda application requirements.

Never Reuse Old Transmission Fluid

Never reuse ATF drained from the failed transmission.

Old fluid can contain:

• Metal particles
• Clutch debris
• Friction material
• Oxidized fluid
• Other contaminants

Instead, start the replacement transmission with fresh, correct-specification ATF.

Inspect the Torque Converter

Compare the replacement torque converter with the original converter.

Check the:

• Hub
• Splines
• Mounting points
• Seal surface
• Overall configuration

Most importantly, fully seat the torque converter inside the transmission before installation.

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

Doing so can damage the transmission pump or converter.

Inspect Accessible Seals

Before installation, inspect:

• Axle seals
• Torque-converter/front seal
• Cooler fittings
• Shift-shaft areas
• Case sealing surfaces

Replacing questionable seals while the transmission remains outside the vehicle can save considerable labor later.

Inspect Sensors and Solenoids

Compare all external electrical components with the original transmission.

Inspect:

• Shift solenoids
• Pressure-control solenoids
• Speed sensors
• Pressure switches
• Range-related components
• Electrical connectors

Look for corrosion, bent pins, damaged wiring, or physical damage.

When necessary, transfer compatible original USDM components.

Inspect Engine and Transmission Mounts

Check the mounts for:

• Cracks
• Separation
• Excessive movement
• Damaged brackets
• Loose hardware

Worn mounts can cause clunking, vibration, or harsh engagement that may incorrectly appear to be a transmission problem.

Inspect the Front Axles

Check both front axles and CV joints.

Look for:

• Damaged splines
• Torn CV boots
• Excessive joint play
• Grease leakage
• Bent components

An axle problem can create vibration or noise that may be mistaken for transmission failure.

Scan the Vehicle Before Removing the Original Transmission

Record all diagnostic trouble codes before removing the failed transmission.

Pay particular attention to:

• Shift-solenoid codes
• Pressure-control codes
• Gear-ratio codes
• Torque-converter codes
• Speed-sensor codes
• Engine codes
• Communication faults

Do not simply erase the codes.

Instead, use them to diagnose external problems that could affect the replacement transmission.

PCM / Transmission Relearn

After installation, complete any applicable Honda or Acura PCM reset, transmission initialization, or relearn procedure.

Use Honda-compatible diagnostic equipment when required.

INITIAL STARTUP CHECKLIST

Before road testing:

• Confirm MFKA transmission code.
• Confirm the physical serial number.
• Verify the vehicle application.
• Confirm K24-Series 2.4L application.
• Verify FWD configuration.
• Fill with fresh, correct Honda/Acura ATF.
• Verify ATF level.
• Check all electrical connectors.
• Inspect sensors and solenoids.
• Verify cooler-line connections.
• Inspect axle seals.
• Check shift linkage.
• Confirm Park engagement.
• Confirm Reverse engagement.
• Confirm Drive engagement.
• Check warning lights.
• Scan for trouble codes.
• Inspect for fluid leaks.

INITIAL ROAD TEST

Begin with a gentle road test.

Monitor:

• Reverse engagement
• Drive engagement
• 1–2 shift
• 2–3 shift
• 3–4 shift
• 4–5 shift
• Downshifts
• Torque-converter lockup
• Shift flare
• Slipping
• Shudder
• Vibration
• Abnormal noise
• Warning lights
• Fluid leaks

Avoid aggressive acceleration until normal transmission operation has been confirmed.

Afterward, inspect for leaks and verify the ATF level again.

Common Signs of Accord / TSX Transmission Problems

A failing automatic transmission may cause:

• Delayed Drive engagement
• Delayed Reverse engagement
• Harsh shifting
• Slipping
• Shift flare
• Shudder
• Failure to upshift
• Torque-converter problems
• Abnormal noises
• Burnt ATF
• Warning lights
• Transmission-related diagnostic codes

However, these symptoms do not always indicate complete transmission failure.

Solenoids, sensors, wiring, pressure switches, torque-converter problems, fluid issues, and worn mounts can create similar symptoms.

Therefore, diagnose the vehicle before replacing the complete transmission.
