RE7R01A Transmission Control Module

The RE7R01A Transmission Control Module is an electronic control unit used with the JATCO JR710E seven-speed automatic transmission found in selected Nissan and Infiniti rear-wheel-drive and all-wheel-drive applications. Nissan service information for the RE7R01A identifies the TCM as part of the control valve and TCM assembly inside the automatic transmission. The TCM works together with transmission speed sensors, temperature sensing, pressure-control solenoids and other hydraulic components to manage gear changes and clutch operation.

This product is intended for professional transmission workshops, electronic repair specialists, rebuilders, distributors and wholesalers. Because several TCM hardware and software revisions exist for the RE7R01A family, customers should compare the complete number on the original module before ordering.

RE7R01A Transmission Control Module Function

The RE7R01A Transmission Control Module receives operating information from the transmission and vehicle systems and uses that information to control the hydraulic circuits required for shifting. The RE7R01A uses multiple clutch and brake elements, and the TCM commands the related solenoids to regulate pressure according to engine load, vehicle speed, selected range and transmission operating conditions.

The TCM is also involved in diagnostic monitoring and communication with other vehicle control modules. A module or control-system problem may contribute to transmission warning lights, communication faults, abnormal shifting, fail-safe operation or pressure-related diagnostic trouble codes.

These symptoms do not automatically confirm that the TCM itself is defective. Wiring faults, damaged connectors, solenoid problems, valve-body wear, speed-sensor faults, low hydraulic pressure or internal transmission damage can produce similar symptoms. Professional diagnosis is recommended before replacement.

JR710E and RE7R01A Identification

The RE7R01A is the Nissan designation for the JATCO JR710E seven-speed automatic transmission. Technical transmission documentation identifies JR710E as RE7R01A and lists it in Nissan 370Z and multiple Infiniti applications.

This distinction is useful because transmission parts may be marketed under either RE7R01A or JR710E. For SEO and product matching, both names can be included, but they should not be confused with the related JR711E / RE7R01B transmission.

Customers should confirm the transmission model and original TCM label rather than relying only on the vehicle name.

TCM Versions and Reference Matching

There is not one universal control-module reference for every RE7R01A application. Current specialist transmission suppliers list several Hitachi TCM versions, including ETC94-100N, ETC94-110N and ETC96-200N, depending on the valve-body design and application.

For example, specialist parts catalogs identify ETC94-100N with one RE7R01A valve-body configuration and ETC94-110N with another configuration. ETC96-200N also appears in current RE7R01A TCM listings. These references should therefore be treated as version-specific TCM identifiers rather than one universal OE for the entire transmission family.

For accurate matching, customers can provide:

• Complete TCM label number
• Transmission model
• Original module photos
• Valve-body casting or configuration
• Connector photos
• Vehicle information
• Required quantity

Clear label photos are especially important when the transmission has already been repaired or the valve body has previously been replaced.

TCM and Valve Body Relationship

On the RE7R01A, Nissan service information shows the control valve and TCM as an integrated transmission assembly. The service manual also lists the TCM, speed sensors, transmission-fluid temperature sensor, range switch and multiple solenoid valves as components within this control-valve-and-TCM section.

This means a RE7R01A TCM should not be confused with an external standalone engine-style ECU. Depending on the product being sold, the customer may be purchasing only the electronic control module, a TCM plate or module attached to the valve body, or a complete valve body and TCM assembly.

The product photos and package contents should clearly show which configuration is supplied.

Programming and Replacement Considerations

A replacement RE7R01A Transmission Control Module may require programming, configuration, initialization or other vehicle-specific procedures after installation. The exact process depends on the module version, vehicle and repair method.

A replacement module should not be advertised as universally plug-and-play unless it has been prepared specifically for the target vehicle. Matching the original TCM reference and hardware revision before installation can reduce compatibility problems.
