Replaces the nine shift, pressure, and lockup solenoids in the Nissan/Infiniti RE7R01A seven-speed automatic on the 370Z, G37, Pathfinder and Titan.
If your Nissan 370Z or Infiniti G37, EX37, M37 or FX with the seven-speed automatic has started banging into gear, flaring between shifts, shuddering at highway cruise or dropping into a fail-safe gear with solenoid codes, this nine-piece kit replaces the electrical control side of the RE7R01A, also known by its Jatco codes JR710E and JR711E. It is the lower-cost repair when testing points at the solenoids and the valve body castings themselves are still healthy.
The RE7R01A is a rear-drive seven-speed, and every one of its shifts is a clutch-to-clutch handoff controlled by the transmission module. The module does not move clutches directly; it drives linear solenoids on the valve body that meter oil to each clutch apply circuit, along with the solenoids that set line pressure and control torque converter lockup. Because one clutch must release at the same instant another applies, a solenoid that responds slowly or delivers a little less pressure than commanded shows up immediately as a flare, a tie-up or a harsh shift. In the photo you can see the layout of the kit: eight solenoids share one body style with a mounting ear and a black nose, and one has a different light-colored nose, matching the mixed solenoid types on the valve body.
Scan for transmission codes and check the fluid condition and level first; low or burnt fluid causes the same complaints. Next, check each solenoid's circuit. Our guide to testing solenoids without a factory scan tool covers resistance and activation checks, and bench testing solenoids covers them once the valve body is out. Also know the competing failure: Sonnax documents that on the JR710E, JR711E, JR712E and RE7R01A, wear in the pilot valve bores lets oil escape and starves the control solenoids, causing delayed engagement, erratic shifts and linear solenoid codes. If your solenoids test good but those symptoms remain, the casting is worn and a complete RE7R01A valve body with solenoids is the right part. If the complaint is only highway shudder, read our converter clutch shudder guide before ordering anything.
This kit is listed for the RE7R01A family from about 2008 on. The standard-duty RE7R01A appears in the Nissan 370Z, the Infiniti G (2008 and later), M, EX37 and the 3.7-liter FX/QX70. The heavy-duty RE7R01B variant was used behind the V8 in the FX50, Armada and the Infiniti QX56/QX80 line, and the listing also names the Titan. The listing mentions Pathfinder too, but most North American Pathfinders used other transmissions, so verify yours. Nissan revised parts during this run, so match the part numbers printed on your old solenoids, or send us your year, model and VIN and we will confirm before it ships. Our transmission parts page lists the rest of our catalog.

The 2008-and-later G models with the seven-speed automatic use the RE7R01A, which this kit is listed for. Compare the part numbers on your old solenoids with the kit or send us your VIN and we will confirm.
Those use the heavy-duty RE7R01B version. The listing names RE7R01B among its part numbers, but because Nissan revised parts during production, send your VIN so we can confirm before it ships.
If testing shows one or more bad solenoids and the valve body bores are healthy, this kit is the economical fix. If solenoids test good but you still have delayed engagement and erratic shifts, the pilot valve bores are likely worn and a complete valve body is the better repair.
Nissan Matic S, or an equivalent fluid that is approved for Matic S applications. Do not substitute a generic multi-vehicle fluid.
Yes. Clear the codes and run the transmission adaptive learn with a scan tool that supports it, then road test. Shifts can feel uneven until the module has relearned clutch fill times.
