Acura RL MJBA Transmission for Sale

Looking for an Acura RL MJBA transmission? J-Spec Auto Sports offers this low-mileage JDM 5-speed automatic SH-AWD transmission for compatible 2005–2008 Acura RL 3.5L applications.

This individual transmission is identified as:

JDM Transmission Code: MJBA
Item ID: 17501
SKU: MT36
Engine: J35A8 3.5L V6
Transmission Type: 5-Speed Automatic
Drivetrain: SH-AWD

Therefore, customers should compare this JDM MJBA unit with their original transmission before purchasing.

2005–2008 Acura RL 3.5L Transmission

The 2005–2008 Acura RL uses a 3.5L V6 engine, 5-speed automatic transmission and Super Handling All-Wheel Drive system.

For this JDM unit, the primary product relationship is:

2005–2008 Acura RL → J35A8 3.5L V6 → MJBA JDM Transmission → 5-Speed Automatic → SH-AWD

As a result, this page should remain tightly focused on the 2005–2008 3.5L generation.

Most importantly, do not include the 2009 Acura RL in the primary fitment because the 2009 model changed to the 3.7L J37A1 powertrain configuration.

Acura RL J35A8 3.5L V6 Application

The J35A8 3.5L V6 is an important search and fitment identifier for the 2005–2008 Acura RL.

Therefore, buyers searching for an Acura RL 3.5L transmission, J35A8 transmission or 2005–2008 RL automatic transmission can find this product through multiple relevant search terms.

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

Consequently, customers should also verify transmission identification, electronics, case configuration and SH-AWD compatibility.

MJBA vs USDM Acura RL Transmission Codes

This JDM transmission carries the MJBA identification.

However, U.S.-market 2005–2008 Acura RL transmissions are commonly referenced with a different transmission designation, including MRJA.

Therefore:

JDM Replacement Unit → MJBA

USDM Original → Commonly MRJA

should be treated as an interchange comparison rather than proof that the two codes are automatically identical.

Before installation, compare the transmission case, bellhousing, torque converter, electrical connectors, sensors, solenoids, range switch, transfer assembly, mounts, cooler fittings and axle connections.

Additionally, compatible original USDM external components may need to be retained or transferred depending on the exact application.

Acura RL SH-AWD Transmission

The Acura RL uses Honda/Acura’s Super Handling All-Wheel Drive (SH-AWD) system.

Therefore, this transmission should not be described simply as a generic Honda 5-speed automatic.

Instead, SH-AWD compatibility is an important part of the product identity.

Before ordering, verify the transmission’s transfer assembly interface and all related AWD drivetrain connections.

Furthermore, make sure the replacement configuration matches the vehicle’s original SH-AWD drivetrain.

2005–2008 Acura RL Transmission Fitment

This JDM MJBA transmission primarily targets compatible:

2005 Acura RL 3.5L SH-AWD Automatic

2006 Acura RL 3.5L SH-AWD Automatic

2007 Acura RL 3.5L SH-AWD Automatic

2008 Acura RL 3.5L SH-AWD Automatic

Nevertheless, exact interchange should be verified before ordering.

Do not automatically extend this fitment to 2009–2010 Acura RL 3.7L applications.

MJBA 5-Speed Automatic Transmission

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

Additionally, the transmission works as part of the RL’s SH-AWD drivetrain.

For that reason, buyers should compare more than the engine and bellhousing.

In particular, verify:

• Transmission identification
• Electrical connectors
• Sensors
• Solenoids
• Range switch
• Torque converter
• Transfer assembly
• SH-AWD interface
• Mounting points
• Axle connections
• Cooler fittings

Most importantly, compare Item 17501 directly with the original transmission before installation.

Acura RL Transmission Installation

Proper installation is essential when replacing an Acura automatic transmission.

First, thoroughly flush the transmission cooler and cooler lines. A failed transmission may leave clutch material, metal particles and contaminated ATF inside the cooling circuit.

Therefore, make sure the cooler system is clean before operating the replacement transmission.

Next, inspect accessible seals while the transmission is outside the vehicle.

In particular, inspect the torque-converter/front seal, axle seals and related drivetrain seals.

Additionally, verify whether the torque converter is included with Item 17501.

If included, make sure the torque converter is completely seated before mating the transmission to the engine.

Most importantly, never use the bellhousing bolts to force the engine and transmission together.

Acura RL Transmission Fluid

Use Honda/Acura Genuine ATF DW-1 unless current VIN-specific Acura service information specifies otherwise.

Additionally, use fresh transmission fluid rather than reusing contaminated ATF from the failed transmission.

After installation, verify the proper ATF level according to the applicable Acura service procedure.

Furthermore, inspect and service related SH-AWD drivetrain fluids separately according to the applicable factory maintenance procedures.

Transmission Relearn and Road Test

After installation, scan the vehicle for engine, transmission and SH-AWD diagnostic trouble codes.

Next, perform applicable reset, initialization or learning procedures.

Then, complete a controlled road test.

Verify Reverse and Drive engagement, all five forward shifts, downshifts and torque-converter lockup.

Additionally, verify proper SH-AWD operation and check for warning lights.

Afterward, inspect for fluid leaks, delayed engagement, slipping, harsh shifting or abnormal noises.

Finally, keep the original transmission until Item 17501 has been successfully installed and road-tested.
