Full overhaul kit for the Nissan and Infiniti RE5R05A 5-speed automatic: clutch frictions, steels, gaskets, seals and filter to rebuild the trans in one box.
The RE5R05A is not only a truck transmission. The same Jatco five-speed sits behind the VQ V6 in the Infiniti G35, FX35 and EX35, behind the V8 in the FX45 and Q45, and in the Nissan Titan, Armada, Frontier, Xterra and Pathfinder. If yours has started flaring on the 3-4 shift, banging into gear, or setting pressure and solenoid codes, and the fluid on the dipstick or drain plug is dark and burnt, the unit needs new soft parts and clutches. This master rebuild kit puts the clutch friction plates, steel reaction plates, gasket and seal set, rubber and metal-clad seals, and the pan filter in one box.
A standard RE5R05A rebuild keeps the hard parts, meaning the drums, shafts, planetaries, pump and valve body, and renews everything that wears or seals. The frictions and steels in each drum are what actually hold a gear. The piston seals and metal-clad seals keep apply oil in each piston so the pack clamps hard and fast. The gaskets and pan filter close up the case and clean the fluid. On a high-mileage unit those parts wear out together, so doing them all in one teardown is the rebuild that lasts. This kit is that parts list, assembled for the RE5R05A, so the bench job is not stalled waiting on one missing seal.
Several RE5R05A complaints that look like clutch failure are really electrical or hydraulic. Infiniti models are a good example: Sonnax notes that Infiniti used a 10-15 ohm low coast solenoid until August 2005 and the 20-40 ohm part after that, so a meter reading that looks bad on an early G35 or FX can be normal for that build. Test the solenoids against the right specification, check line pressure, and look hard at the fluid. Our Nissan and Infiniti RE5R05A service guide covers the pressure and solenoid checks in order. If the fluid is burnt and the pan holds clutch debris, the clutches are gone and an overhaul is the fix.
This kit is listed for the RE5R05A five-speed rear-wheel-drive automatic in the Nissan Titan, Armada, Frontier, Xterra and Pathfinder, and the Infiniti FX35, FX45, G35, EX35 and Q45. The listing does not narrow that to specific years, and the RE5R05A saw running changes through its production, so a 2004 Titan drum stack is not identical to a later Pathfinder. Confirm the unit is an RE5R05A on the transmission tag, not the older four-speed RE4R01A or a CVT, and check your clutch plate counts against the service manual. If you want the kit checked against your vehicle before it ships, send us the year and VIN. Every RE5R05A part we carry is on the RE5R05A collection page.
Expect a full day on the bench for this job with a service manual for clearances.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the RE5R05A in the Infiniti FX35, FX45, G35, EX35 and Q45. Confirm the transmission tag reads RE5R05A, since the listing does not narrow fitment by year.
Clutch friction plates, steel plates, gaskets, seals including rubber and metal-clad seals, and the pan filter.
Not automatically. A standard rebuild reuses the drums, shafts, pump and valve body. Replace any that show scoring, cracks or wear during teardown.
Possibly not. Sonnax notes that Infiniti used a 10-15 ohm low coast solenoid until August 2005 and a 20-40 ohm solenoid after that. Test against the specification for your build date.
Nissan Matic-S ATF, with Matic J as the approved alternative. Set the level hot by the check procedure.
