RE5R05A Clutch Drum 2007, used and ready to install. Fits the RE5R05A. Ships fast from the USA.
A 2007 Nissan Armada that bangs into second, slips on the 1-2 shift, or came apart with a cracked or heat-damaged drum needs a replacement hard part before any rebuild kit will hold. This is a used, original-equipment RE5R05A direct clutch drum with the high-low clutch section, sold loaded with its clutch pack as shown in the photos. It was removed from a 2007 Armada LE and carries a 1-year warranty, so you can replace a damaged drum without paying for a complete core transmission.
The RE5R05A builds its five forward gears by applying combinations of clutches and brakes around its planetary gearsets. The direct clutch is the element that comes on for the 1-2 upshift, so the quality of that shift depends on how quickly and cleanly this drum's piston strokes and clamps the pack. Apply oil reaches the spinning drum through sealing rings that ride in steel ring lands on the support. On a high-mileage Armada, three things go wrong here: the drum itself cracks or its piston bore scores, the clutch pack burns from towing heat, or the ring lands wear so pressure leaks before it reaches the piston. ATRA's Gears Magazine documented an RE5R05A with a harsh 1-2 shift that took 70 psi of regulated air just to move the direct clutch, compared with 50 psi once the leak was fixed.
Start with the basics outlined in our RE5R05A service guide: correct fluid level, fluid condition and any stored codes. The Armada, like other RE5R05A trucks, runs its fluid through a cooler inside the radiator, and Sonnax reports that about half the cores it sees have water contamination from a failed cooler, which destroys clutches fast. On the bench, air check the direct clutch with no more than 50 psi of regulated air, inspect the drum for cracks and bore scoring, and measure each sealing ring against its land. Gears Magazine expects about 0.005 inch of clearance and found a worn land at 0.018 inch. If the drum is the damaged piece, this is the replacement.
This drum came out of a 2007 Nissan Armada LE with the 5.6L V8 and RE5R05A 5-speed automatic. Nissan used the RE5R05A across many trucks, SUVs and cars, and drum revisions differ between applications, so compare the drum, spline count and clutch stack against the part you removed before you install it, or send us your year and VIN and we will check it. If you are working on a 2003-2005 car unit instead, see the 2003-2005 RE5R05A input drum stack. All parts for this transmission are on the RE5R05A collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is the used direct clutch drum with the high-low clutch section, shipped loaded as shown in the photos. We still recommend new frictions, steels and seals from a rebuild kit when you install it.
It was removed from a 2007 Armada with the 5.6L V8. Other RE5R05A applications may use the same drum, but revisions vary, so compare it with your old drum or send us your year and VIN to check before ordering.
The direct clutch applies on the 1-2 shift, so a damaged drum, a leaking piston seal or worn sealing ring lands can all cause it. Software and valve body faults can too, which is why you should check codes and fluid first.
Nissan specifies Genuine Nissan Matic S ATF for its RE5R05A trucks. Check your owner's manual for your exact model and fill to the hot level.
If the fluid shows any milky or pink contamination, yes. Water from a failed radiator cooler is one of the most common ways these transmissions are ruined, and it will damage new parts the same way.
