For example, INFINITI lists the 2014–2015 Q60 3.7L with a 7-speed automatic and either RWD or AWD configurations.

However, sharing a 7-speed transmission family does not guarantee direct interchangeability.

Therefore, contact J-Spec Auto Sports before purchasing this transmission for anything other than the primary advertised application.

Important RWD vs. AWD Warning

This transmission is intended for rear-wheel-drive applications.

A RWD automatic transmission should not be assumed to interchange with an AWD transmission.

The AWD drivetrain uses additional components and a different output arrangement.

Therefore, confirm your vehicle is RWD / 2WD before ordering.

If you have an AWD G37, Q50, Q60, M37, or related application, contact us for the correct transmission.

Important Transmission-Code Verification

Transmission fitment depends on more than:

• Engine code
• Displacement
• Number of gears
• Vehicle model

The exact transmission identification is extremely important.

Before ordering, compare:

• Transmission code
• ID tag
• Case markings
• Electrical connectors
• Sensor locations
• Oil cooler connections
• Bellhousing
• Output shaft
• Mounting locations

Whenever possible, send us clear photographs of the original transmission identification label.

This step can significantly reduce installation and fitment problems.

RE7R01A / JR710E Transmission Family

Many rear-wheel-drive Nissan and INFINITI 7-speed automatic applications use the RE7R01A, also known by JATCO as the JR710E.

This transmission family uses seven forward gears and a longitudinal layout for rear-wheel-drive applications.

However, several revisions and vehicle-specific versions exist.

Therefore, do not assume that any transmission labeled RE7R01A or JR710E will automatically work in every Nissan or INFINITI application.

Most importantly, verify the code on the actual transmission being purchased.

What Is Included?

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

Some additional components may remain attached.

However, unless J-Spec Auto Sports specifically lists those parts as included and covered, consider attached components convenience items.

Possible attached items may include:

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

Therefore, review the actual product photographs carefully before ordering.

Is the Torque Converter Included?

If a torque converter appears with the transmission in the actual product photos, it may remain attached to the unit.

However, buyers should confirm torque-converter inclusion before purchase.

In addition, your installer should inspect the converter before installation.

A contaminated or damaged torque converter can cause problems even when the replacement transmission itself is serviceable.

Inspect the Original Transmission Failure

Before installing a replacement transmission, determine why the original unit failed.

For example, failure may result from:

• Internal clutch damage
• Valve-body problems
• Solenoid problems
• Low fluid
• Contaminated fluid
• Torque-converter failure
• Transmission overheating
• Cooler restriction
• Electrical problems
• TCM-related issues

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

Transmission Cooler and Cooler-Line Service

This is one of the most important steps during transmission replacement.

If the original transmission suffered an internal failure, metallic debris or clutch material may remain inside the transmission cooler and cooler lines.

Therefore, inspect and properly flush the cooler system before connecting 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 component.

Otherwise, debris from the failed transmission may enter the replacement transmission.

Inspect the Torque Converter

Before installation, inspect the torque converter.

Check for:

• Contamination
• Abnormal play
• Damaged hub
• Damaged splines
• Leakage
• Metal debris

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

Instead, replace or professionally service the converter as appropriate.

Use the Correct Automatic Transmission Fluid

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

Do not select fluid simply because another Nissan or INFINITI transmission uses it.

The installer should verify the correct fluid specification through the appropriate Nissan/INFINITI service information for the vehicle.

In addition, follow the correct temperature-based fluid-level procedure.

Improper fluid type or fluid level can cause poor shifting and transmission damage.

Check Fluid Level Correctly

Modern sealed automatic transmissions require a specific fluid-level procedure.

Therefore, do not simply add a predetermined amount of fluid and assume the level is correct.

The installer should:

1. Fill the transmission with the correct fluid.
2. Follow the proper warm-up procedure.
3. Monitor transmission-fluid temperature as required.
4. Cycle the shifter through the appropriate gear positions.
5. Check the 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

The current listing correctly warns that electronic reprogramming may be necessary.

Depending on the application, the vehicle may require:

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

Therefore, do not assume that every replacement transmission will operate correctly immediately after mechanical installation.

A qualified Nissan/INFINITI technician or properly equipped repair facility may need to complete programming or relearn procedures.

Do Not Swap Valve Bodies Without Verification

Some installers attempt to transfer the original valve body or TCM when dealing with compatibility issues.

However, do not automatically swap valve bodies, control modules, or internal electronics without confirming compatibility.

Transmission revisions can differ.

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

Inspect Rear Main Seal While Transmission Is Out

Transmission removal provides access to areas that are normally difficult to reach.

Therefore, inspect the engine rear main seal while the transmission is removed.

If the seal shows leakage, address it before installing the replacement transmission.

This preventive step may save considerable labor later.

Inspect Transmission Mount

Inspect the transmission mount for:

• Cracking
• Separation
• Oil saturation
• Excessive movement
• Damaged hardware

Replace a worn mount before installation.

A damaged mount can create vibration, movement, and driveline noise.

Inspect Driveshaft and Related Components

Before reinstalling the drivetrain, inspect:

• Driveshaft
• Flex coupling where applicable
• U-joints where applicable
• Center support where applicable
• Differential input area
• Transmission output seal
• Driveshaft flange
• Hardware

As a result, you can address driveline problems while the transmission remains out of the vehicle.

Replace Accessible Seals

Before installing the replacement transmission, inspect:

• Front pump seal
• Torque-converter seal
• Output-shaft seal
• Cooler-line seals
• Electrical connector seals
• Other accessible external seals

If a seal shows leakage or damage, replace it while access remains easy.
