Full master rebuild kit for the Nissan RE5R05A/JR507E 5-speed: 32 frictions, 34 steels, seals, gaskets and rings for Titan, Armada, Frontier and Pathfinder.
High-mileage Nissan Titans and Armadas are the most common trucks to need this kit. The 5.6L VK56 makes a lot of torque, many of these trucks tow, and the RE5R05A five-speed (Jatco JR507E) eventually burns its direct and high clutches. If your truck is flaring on the 2-3 or 3-4 shift, holding a gear, or setting slip codes, this master rebuild kit carries the plates and the full gasket and seal set to overhaul the unit on the bench: 32 friction plates, 34 steel plates, plus seals, gaskets, rubber rings, sealing rings and thrust washers.
The RE5R05A uses several clutch packs and a front brake band, applied in combinations by the valve body under TCM control. In a Titan or Armada the heaviest load lands on the clutches that make the upper gears, and once their frictions glaze, every shift into those gears gets longer until the TCM flags a ratio error. Cleaning or reusing those plates is a false saving. This kit replaces every friction and steel along with the sealing parts, so each pack applies with full pressure and the factory clearance. The included sealing rings matter here: the rotating rings on the drums and support are what carry apply oil to the clutches.
Scan for codes, then look at the fluid. Electrical faults and solenoid problems are common on the RE5R05A too, and Sonnax publishes solenoid identification data and resistance specs so you can test before tearing anything down. If the fluid is clean and the problem is a single harsh shift, our RE5R05A service guide covers pressure and solenoid checks. If the fluid is burnt or milky and the clutches are gone, this kit is the right starting point.
This kit is listed for the Nissan RE5R05A / Jatco JR507E five-speed across 2004-2014: Titan and Armada 5.6L, Frontier 2.5L and 4.0L, Pathfinder and Xterra, the 350Z, the Infiniti QX56 and the Suzuki Equator. That is a broad list, and the RE5R05A did change during production, including three valve body designs and a solenoid resistance change in Infiniti applications in August 2005. Confirm your transmission is an RE5R05A from the case tag, and send us your year and VIN if you want the kit matched before it ships. Every RE5R05A part we stock is on the RE5R05A collection page. Owners of the 4.0L Pathfinder, Xterra or Frontier can also compare the 2006-2011 4.0L master kit.
Professional installation is recommended for this bench rebuild.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
32 friction plates and 34 steel plates, along with seals, gaskets, rubber rings, sealing rings and thrust washers.
Neither is listed. Add the RE5R05A filter and pan gasket kit, and inspect the band during teardown.
Yes. JR507E is Jatco's name for the unit Nissan calls the RE5R05A.
Not necessarily. Check the support sealing ring lands and the valve body first. ATRA documented a harsh 1-2 on an RE5R05A caused by worn ring lands, not by the clutches.
