Master overhaul kit for the RE5R05A 5-speed behind the 4.0L V6 in 2006-2011 Pathfinder, 2007-2011 Xterra and 2006-2010 Frontier trucks.
This master rebuild kit is for one specific group of trucks: the 2006-2011 Nissan Pathfinder 4.0L, the 2007-2011 Xterra 4.0L and the 2006-2010 Frontier 4.0L. All three put the Jatco RE5R05A five-speed (Jatco code JR507E) behind the VQ40DE V6. If yours is slipping in 4th and 5th, slamming into gear, or has the strawberry-milkshake fluid that follows a radiator cooler failure, this kit renews the internals so the unit can go back in service instead of being swapped for a used core of unknown history. Transmission part number reference: 31728-97X00.
On these 4.0L trucks the RE5R05A works hard. Many of them tow, and the VQ40 makes plenty of torque low in the rev range, so the clutch packs carry a heavy load on every upshift. A master kit replaces the wear and sealing parts of a full overhaul: the frictions and steel plates that make each gear, and the gaskets and seals that hold line pressure in every circuit. Renewing all of it in one teardown means each clutch pack applies at the same rate the TCM expects, which is what brings shift quality back.
The coolant question comes first on these years. The Frontier and Pathfinder of this era are well known for the transmission cooler inside the radiator failing and mixing coolant into the ATF. Transmission Digest has documented RE5R05A converter shudder showing up after a cooler failure was repaired, because the contamination had already done its damage. Pull the pan: pink or milky fluid means overhaul. Clean fluid with a shift complaint sends you toward solenoid and valve body tests instead. Our RE5R05A transmission service guide covers the fluid, pressure and solenoid checks in order.
Listed fitment: Nissan Pathfinder 4.0L 2006-2011, Nissan Xterra 4.0L 2007-2011 and Nissan Frontier 4.0L 2006-2010, all with the 3954cc VQ40DE V6 and the RE5R05A in rear-drive or four-wheel-drive form. It is not listed for the 2.5L four-cylinder Frontier or for the 5.6L Titan and Armada. Sonnax documents three different RE5R05A valve body designs that should not be interchanged, which is a good reminder that this transmission changed over its life. Check the tag on the case against the 31728-97X00 reference or send us your year and VIN. You can also compare every part we carry on the RE5R05A collection page. If you want the brake band included, see the RE5R05A master kit with brake band and filter.
This is a bench rebuild. Professional installation is recommended if you do not have the tools to measure clearances.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is listed only for the 4.0L V6 in the 2006-2010 Frontier, 2006-2011 Pathfinder and 2007-2011 Xterra. Send your VIN if you are unsure what is in your truck.
The listing does not include a band. If your band is glazed or worn, our RE5R05A master kit with brake band and filter covers the same 4.0L trucks with those items added.
Coolant that got into the ATF before the repair can leave the frictions and converter damaged. Transmission Digest has documented exactly that on the RE5R05A, and a full overhaul is the usual fix.
Nissan Matic-S ATF, the fluid Nissan specifies for this transmission.
Not always. Inspect and test it. On coolant-damaged units or units with solenoid codes, replacing or rebuilding the valve body during the same job avoids a second removal.
