RE5R05A Master Rebuild Kit, new and ready to install. Fits the RE5R05A. Ships fast from the USA.
When a Nissan Frontier, Xterra, Pathfinder, Titan or Armada, or an Infiniti QX56, has an RE5R05A five-speed that slips in gear, flares on the shifts, smells burnt, or came back from a radiator cooler failure with pink, milky fluid, the cure is a full overhaul rather than a patch. This RE5R05A master rebuild kit gives you the soft parts for that overhaul in one box: the friction plates and steel plates for the clutch packs, plus the gasket and seal sets that reseal the case, pump and pistons.
The RE5R05A is a rear-wheel-drive Jatco five-speed that first went into the 2002 Infiniti Q45 and was used across Nissan's body-on-frame trucks and SUVs for more than a decade. Its gears are applied by a set of multi-plate clutches and a band, each fed through rotating sealing rings from the valve body. Over time the frictions glaze or burn, the piston and ring seals harden, and the unit loses holding pressure. A master kit lets you renew every friction surface and every seal in the same job, so a fresh clutch pack is not being fed by a tired seal next to it.
Check fluid level and condition first; a valve body or solenoid fault on this transmission can feel like slipping without the clutches being burnt. Pull the pan and look at what is on the magnet and in the filter. If the fluid is clean and there is no friction debris, read our RE5R05A service guide and test the RE5R05A solenoids before committing to an overhaul. If coolant got into the fluid, budget for the rebuild and a new radiator: Sonnax reports roughly half of the cores it sees have water intrusion from failed coolers.
This kit is listed for the RE5R05A without a specific year range. The unit was built from 2002 into the late 2010s and was revised along the way, including three different valve body designs that Sonnax notes should not be interchanged. Kit contents can vary between early and late builds and between the 2WD and 4WD trucks, so before ordering, send us your year, model, engine and VIN, or compare the kit to your teardown. Other RE5R05A parts, including hard parts and valve bodies, are on the RE5R05A parts page.
Inspect the drums, bushings, pump and planetary carriers before you build; a kit cannot fix scored or worn hard parts, and a cracked RE5R05A input drum is worth replacing while the unit is apart. Pay special attention to the sealing ring lands on the support. GEARS Magazine documented a rebuilt 2007 Frontier with a harsh 1-2 shift that came back three times; the cause was ring land wear of 0.018 inch against an expected 0.005 inch, which starved the direct clutch. Measure every land with a new ring, and air check each clutch with no more than 50 psi of regulated air. Soak new frictions in fluid, set clutch clearances to the factory specification, and prime the pump on assembly. Refill with Nissan Matic S ATF, flush or replace the cooler and lines, and if the truck had coolant contamination, replace the radiator before the rebuilt unit goes back in.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Nissan Frontier, Xterra, Pathfinder, Titan and Armada and the Infiniti QX56 are the common ones, along with earlier Infiniti models starting with the 2002 Q45. Send your VIN to confirm your build before ordering.
Coolant attacks the friction bonding, so the frictions must be replaced, which this kit covers. Also replace the radiator with its built-in cooler, flush the lines, and check the torque converter, or the rebuilt unit can be contaminated again.
Nissan specifies Genuine Nissan Matic S ATF for these transmissions. Check your owner's manual for the exact capacity of your model.
A known cause is wear in the sealing ring lands on the support, which lets direct clutch pressure leak. Measure ring clearance with new rings during the rebuild and air check the clutch before assembly.
No. A master kit covers soft parts such as frictions, steels, seals and gaskets. Drums, planetaries, solenoids and valve bodies are sold separately if your inspection shows they are worn.
