RE4F04A Valve Body, remanufactured and ready to install. Fits the RE4F04A. Ships fast from the USA.
If your Nissan Altima, Maxima, Sentra SE-R 2.5L, Quest, or Infiniti I30/I35 is shifting harsh, flaring between gears, hunting or surging at steady highway speed, or dropping into limp mode with a stored code, the RE4F04A valve body is one of the first places to look. This listing is a remanufactured, bench-ready valve body for the RE4F04A, built to go in as a known-good unit instead of you chasing individual bores, solenoids, and springs on the bench.
The RE4F04A is Nissan's electronically controlled four-speed front-wheel-drive automatic, and the valve body is its hydraulic control center. It routes pressurized fluid from the pump through a maze of spool valves and separator plates to apply and release each clutch pack and band on command, and it carries the shift solenoids and torque converter clutch (TCC) solenoid that the transmission control unit fires based on throttle position, vehicle speed, and gear selector input. When the bores wear, a separator plate warps, or a solenoid sticks, the whole shift strategy degrades even though the clutches themselves may still be good.
None of these codes prove the valve body itself is bad on their own — a sticking solenoid, a wiring fault, or a worn speed sensor can set the same codes. That is why the next step matters before you buy.
Pull the stored codes and watch live data for shift-solenoid and TCC-solenoid duty cycle while you drive it, since a solenoid that never actuates points at the valve body or its wiring rather than a mechanical clutch problem. Our guide to reading transmission live data walks through which parameters to watch. If the TCC symptom is a shudder rather than a hard code, our torque converter clutch shudder diagnosis guide covers how to tell a converter problem from a valve body or fluid problem before you spend money on the wrong part.
This valve body fits the RE4F04A as used across the Nissan Altima, Maxima, Sentra SE-R 2.5L, Quest, and Infiniti I30/I35 lineup. Sources differ on the exact model-year cutoffs for this transmission, and Nissan used more than one valve body casting over the RE4F04A's production run — the two are not interchangeable, and a kit or valve body built for one will not correct shifts on the other. If your vehicle falls in the 1993-2000 range, see our RE4F04A Valve Body 1993-2000 listing, built specifically around that earlier casting. Otherwise, compare the bore pattern and mounting-bolt count on your old valve body against this one, or send us your year, make, model, and VIN before ordering so we can confirm the casting matches.
Change the fluid and filter at the same time you install this valve body so metal and clutch debris from the old unit's failure does not immediately contaminate the new one. Torque the valve body bolts down in sequence to spec rather than cranking them corner to corner, since an uneven bolt pattern can warp the separator plate and bring the same symptoms right back. On this electronically controlled unit, run the transmission control unit's adaptive relearn after the install — our adaptive relearn guide covers the procedure. If the solenoids or pump are original-mileage, pair this valve body with our RE4F04A Solenoid Kit or RE4F04A Pump rather than bolting a new valve body to worn electrical or hydraulic components.

They are different codes with a different internal valve layout, and parts built for one are not a direct swap onto the other. Confirm which code your transmission carries from the tag on the case before ordering, since the two are easy to mix up in parts listings.
Usually, but not always. Those codes point at the TCC solenoid circuit and the pressure control solenoid respectively, both of which live in the valve body, but a wiring fault or a bad connector can set the same code. Check the harness and connector at the valve body before you rule that out.
Nissan changed its Matic-fluid specification across this platform's long production run, so confirm the correct type for your exact year from the underhood fluid label or your owner's manual rather than assuming one spec covers the whole range.
Yes. The RE4F04A's transmission control unit adapts shift feel over time, and that learned data should be reset after a valve body swap so the new unit isn't fighting old adaptive values. See our adaptive relearn guide linked above for the steps.
At minimum, the filter and pan gasket. If the solenoids or pump are original to the vehicle, replacing them alongside the valve body avoids paying for labor twice when one of them fails a few months later.
