Depending on the exact unit, related applications may include certain:

• INFINITI M37
• INFINITI Q40
• INFINITI Q50 3.7L
• INFINITI Q60 3.7L

For example, INFINITI offered the 2014–2015 Q60 3.7L with a 7-speed automatic and either RWD or AWD. Likewise, official INFINITI parts data shows separate Q50 3.7L RWD and AWD transmission assemblies.

Therefore, the fact that two vehicles use a 7-speed automatic does not guarantee direct interchangeability.

Always verify the exact transmission before purchase.

Important RWD vs. AWD Warning

This transmission is intended for RWD applications.

RWD and AWD transmission configurations differ.

Therefore, do not assume that a RWD transmission will replace an AWD unit.

If your G37, Q50, Q60, M37, or related vehicle is AWD, contact J-Spec Auto Sports before ordering.

Important Transmission-Code Verification

Transmission identification matters more than the basic engine code alone.

Before ordering, compare:

• Transmission identification code
• ID tag
• Case markings
• Electrical connectors
• Sensor locations
• Cooler fittings
• Bellhousing
• Output shaft
• Mounting points

Whenever possible, send us clear photos of your original transmission tag and connectors.

That step can help prevent costly fitment problems.

RE7R01A / JR710E Transmission Family

Many Nissan and INFINITI longitudinal 7-speed RWD applications belong to the RE7R01A / JATCO JR710E transmission family.

However, several vehicle-specific versions and internal revisions exist.

Therefore, do not purchase based only on the RE7R01A or JR710E family name.

Confirm the actual unit code and vehicle application first.

What Is Included?

The primary item for sale is the JDM 7-speed RWD automatic transmission assembly shown in the product photos.

Some attached parts may remain with the transmission.

However, unless J-Spec Auto Sports specifically states that a component is included and covered, consider attached components convenience items.

Possible attached items may include:

• Torque converter
• Sensors
• Wiring
• Brackets
• Cooler fittings
• Transmission mounts

Therefore, review the actual product photos carefully before ordering.

Is the Torque Converter Included?

If a torque converter appears in the actual product photos, confirm its inclusion before purchase.

In addition, inspect the converter before installation.

If the original transmission suffered severe internal failure, do not automatically reuse a contaminated torque converter.

Determine Why the Original Transmission Failed

Before installing a replacement transmission, determine the cause of the original failure.

Common causes may include:

• Internal clutch damage
• Valve-body problems
• Solenoid failure
• Low fluid
• Contaminated fluid
• Torque-converter damage
• Overheating
• Restricted cooler
• Wiring problems
• Control-module issues

Therefore, replacing the transmission without correcting the original cause may damage the replacement unit.

Flush or Replace the Transmission Cooler System

If the original transmission suffered internal damage, metal particles or clutch material may remain inside the cooler and cooler lines.

Therefore, inspect and properly clean the transmission cooling system before installing the replacement transmission.

Check:

• Transmission cooler
• Cooler lines
• Cooler hoses
• Fittings
• Radiator-integrated cooler where applicable

If contamination cannot be removed safely, replace the affected components.

Otherwise, debris may enter the replacement transmission.

Inspect the Torque Converter

Inspect the torque converter for:

• Metal contamination
• Damaged splines
• Hub wear
• Leakage
• Abnormal play
• Physical damage

If the original transmission suffered catastrophic failure, replace or professionally service the converter as appropriate.

Use the Correct Automatic Transmission Fluid

Always use the exact fluid specified for the vehicle and transmission application.

Do not assume that every Nissan or INFINITI 7-speed transmission uses identical service procedures.

Your installer should verify the correct fluid specification and level-setting procedure before installation.

Set the Fluid Level Correctly

Modern automatic transmissions require a specific fluid-level procedure.

Therefore, your technician should:

1. Fill the transmission with the correct fluid.
2. Follow the proper warm-up procedure.
3. Monitor fluid temperature when required.
4. Cycle through the appropriate gear positions.
5. Check fluid level according to service procedures.
6. Correct the level before road testing.

Both overfilling and underfilling can cause transmission problems.

ECU / TCM Programming May Be Required

Electronic programming or relearn procedures may be necessary after installation.

Depending on the vehicle, this may include:

• TCM initialization
• ECU/TCM relearn
• Diagnostic reset
• Adaptation
• Programming
• Calibration

Therefore, do not assume that the vehicle will shift correctly immediately after mechanical installation.

A properly equipped Nissan/INFINITI repair facility may need to complete the required procedures.

Do Not Swap Valve Bodies Without Verification

Do not automatically transfer the old valve body or control electronics into the replacement transmission.

Transmission revisions and calibrations may differ.

Therefore, compare part numbers, connector configuration, and service information before transferring internal components.
