RE4F04A Valve Body 1999-2013, remanufactured and ready to install. Fits the RE4F04A. Ships fast from the USA.
This remanufactured RE4F04A valve body is listed for 1999-2013, a span that takes in the Nissan Altima, Maxima, Sentra SE-R 2.5L and Quest, the Infiniti I30 and I35, and the Mercury Villager. Buyers usually find it after one of the classic RE4F04A complaints: the car falls out of gear at a stop when hot, there is no third gear after a kickdown, the 1-2 and 2-3 shifts swing between harsh and mushy, or the lockup will not engage. The most important thing to know about this listing is that its year range crosses Nissan's switch between two different valve body designs, so the fitment section below matters more than usual.
The RE4F04A, later renamed JF403E by Jatco, is a front-drive electronic four-speed. The pump supplies oil, and the valve body turns it into regulated line pressure, then sends it through a separator plate and steel checkballs to each clutch and to the band. Shift solenoids pick the gear, a pressure control solenoid shapes how firmly each shift applies, and a separate circuit runs torque converter lockup. The 1-2 regulator valve is the known weak spot. Its edge strikes a partition in its bore, deforms the bore and the valve starts to stick. A sticking regulator can produce runaway line pressure, and TransGo warns that this is how clutch drums blow out and planetaries fail.
Read the fluid before anything else. Our ATF color and smell chart shows how to tell normal wear from burnt clutches; heavy friction debris means the clutches are already damaged and a valve body alone will not save the unit. Next, check the electrical side. Shift, pressure control and lockup solenoids can be tested at the case connector with a meter, as shown in our solenoid testing guide. If they pass and the shift complaints remain, the hydraulics in the valve body are the most likely cause.
TransGo's identification sheet splits the RE4F04A into A and V bodies and B bodies. A and V bodies were used in the 1992-1999 Maxima, 1993-1999 Altima, 1995-1999 Infiniti I30 and the 1993-2002 Quest and Villager, plus the 2004 Maxima SL and some 2004-2006 Quest trims. B bodies went into the 2000-2003 Maxima, 2000-2006 Altima, 2000-2006 Sentra SE-R 2.5L, 2000-2001 I30 and 2002 I35. The two are not interchangeable: they use different lockup control, and on the outside the A and V harness passes out through the case while the B harness stays inside. On the casting, A and V bodies have two holes in the identifying area and B bodies have one. Even the shared parts can mislead; Sonnax notes both types use the same manual valve, so a matching manual valve proves nothing. The years past 2006 come from the listing itself, not from the TransGo chart, so before you order, compare your old body with the photos or send us your year, model and VIN. B-body Maxima and I35 owners should also look at our RE4F04B valve body for the Maxima and I35, and earlier cars at the 1992-2000 RE4F04A valve body.
The valve body is reached by dropping the pan with the transaxle in the vehicle. Unplug the solenoid harness, note where each checkball and bolt length goes, and lower the body straight down so the manual valve clears its link. Torque the bolts gradually and evenly. Replace the filter and pan gasket, flush out as much old fluid as you can, and refill with the Nissan Matic-type ATF your owner's manual specifies, since the recommended fluid changed over these model years. If the solenoids are original, a RE4F04A solenoid kit is worth adding while everything is apart, and a weak lockup on the road test points to the RE4F04A TCC solenoid.

A 2004 Altima uses the B body RE4F04A. Make sure the body you receive matches yours: the B harness stays inside the case and the casting has one hole in the identifying area. Send your VIN and we will confirm.
No. The A or V body and the B body differ in casting, harness routing and lockup control, so use the same type that came out of your transmission.
That is a classic sign of 1-2 regulator valve and bore wear in the valve body. Fix it early, because runaway line pressure can damage the clutch drum and planetary.
A filter and pan gasket every time, and the solenoids if they are original or testing out of range. A lockup complaint after the swap points to the TCC solenoid.
It uses Nissan Matic-series ATF, and the specification changed across these model years. Use the fluid listed in your owner's manual or on the dipstick.
