RE5R05A Solenoid Kit 2005-2021, new and ready to install. Fits the RE5R05A. Ships fast from the USA.
This is a new RE5R05A solenoid kit for the 2005-2021 production years of Nissan's five-speed rear-drive automatic, the transmission behind the Frontier, Xterra, Pathfinder, Titan, Armada and Infiniti QX56 of that era. If your truck or SUV is throwing shift solenoid codes, flaring between gears, engaging hard into drive or sitting in limp mode, a full solenoid set is the most direct repair once the fluid and wiring check out.
On the RE5R05A every shift is decided electronically. The control module energizes solenoids on the valve body, and those solenoids route oil to the input and direct clutches, the front brake band, the low coast brake, the high and low/reverse circuits, the converter clutch and the line pressure regulator. A solenoid is a small coil and plunger; with miles and heat the coil resistance drifts and the seat wears, so it leaks oil when it should hold or responds late. The computer has no way to see that, so it keeps commanding shifts the hydraulics can no longer deliver.
The 2005-and-later window matters for this unit. Sonnax notes that Nissan has always used the high resistance low coast solenoid, about 20-40 ohms, while Infiniti valve bodies built before August 2005 used a 10-15 ohm version. A kit for 2005-2021 is aimed at the high resistance era, which covers the large majority of Nissan trucks and SUVs on the road.
Pull the codes and note whether they are circuit faults or performance faults. Circuit faults with a clean harness point at a coil; performance faults can also come from worn valve body bores. Measure each solenoid's resistance at the valve body connector and compare it with the published spec for that solenoid type. Check the fluid for burnt smell or a milky, pink look, since a failed radiator cooler puts coolant into the RE5R05A and ruins solenoids fast. The RE5R05A transmission service guide covers the code list, fluid spec and the pilot valve wear that can mimic a bad solenoid.
The listing covers RE5R05A applications from 2005 through 2021. Solenoids for this unit were made by Bosch, Nachi and Mitsubishi, and a single vehicle can carry more than one style, so compare the kit photo with the solenoids on your valve body and check connector shape and mounting tab before you install. If you have an early-2005 Infiniti QX56, measure your old low coast solenoid: a 10-15 ohm reading means you need the early low-resistance part, not this set. Send us your year and VIN if you are unsure. The RE5R05A collection lists every solenoid kit we carry; 2004 owners should look at the 2004 RE5R05A solenoid kit instead.
If shift feel is still firm or soft after new solenoids, the valve body itself may be worn. A RE5R05A shift kit or a complete valve body is the next step rather than a second solenoid set.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Nissan used it in the Frontier, Xterra, Pathfinder, Titan and Armada, and Infiniti used it in the QX56, among others. Match your existing solenoids to the kit rather than going by model name alone.
Possibly. Infiniti valve bodies built before August 2005 used a 10-15 ohm low coast solenoid. Measure your old one; if it reads 20-40 ohms this high resistance set is the right type.
Sonnax states the high resistance solenoids from those makers can be interchanged as long as resistance matches, which is why checking resistance matters more than the brand.
At minimum a new filter and pan gasket. Replace the internal harness if it is heat-cracked, and replace the radiator or cooler if you find coolant in the fluid.
Genuine Nissan Matic S ATF, with Matic J as the approved alternative. Check the level at operating temperature after the relearn drive.
