RE4F04A Valve Body 1993-2000, remanufactured and ready to install. Fits the RE4F04A. Ships fast from the USA.
Early-production RE4F04A automatics in 1993-2000 Nissan Altima and Maxima models develop a specific set of shift complaints as the valve body wears: hard or soft shifts on the 1-2 and 2-3 change, slipping out of gear at a stop, and a hunt or surge at steady highway speed. This listing is a remanufactured valve body built specifically for the 1993-2000 RE4F04A, not a universal part reused across every year this transmission was built.
In the 1993-2000 RE4F04A, the valve body is the hydraulic and electronic control hub bolted to the underside of the transmission. It takes pressurized fluid from the pump and directs it through spool valves and a separator plate to apply each clutch pack and band in sequence, while the shift solenoids and torque converter clutch (TCC) solenoid mounted on it fire based on commands from the transmission control unit. Everything about how this transmission shifts — firm or soft, on time or late — runs through this one assembly.
A workshop note on this exact valve body generation also warns against swapping in a firmer pilot-valve spring as a quick fix — that modification is documented for the later RE4F04B layout and is not a safe substitute repair on this earlier RE4F04A casting, so don't let a shop talk you into it as a shortcut.
Scan for stored codes first, then watch shift-solenoid and TCC-solenoid duty cycle on a live-data stream while driving, since a solenoid that never actuates points to the valve body or its wiring rather than worn clutches. Our guide to reading transmission live data covers which parameters matter here. If the main complaint is a shudder rather than a logged code, check our torque converter clutch shudder diagnosis guide before assuming it's the valve body.
This valve body is built for the RE4F04A as installed in 1993-2000 Nissan Altima and Maxima models. Nissan revised this transmission's valve body more than once over its full production run, and sources vary on exactly where the cutoffs between castings fall, so a 1993-2000 label is not a guarantee against every build variation inside that window. Compare the bolt pattern and bore layout on your old valve body against this one before installing, or send us your year, make, model, and VIN so we can confirm fitment. If your vehicle falls outside this 1993-2000 range, see our general RE4F04A Valve Body listing instead.
Drop the pan and change the fluid and filter at the same time as the valve body so contamination from the old failure doesn't carry over. Torque the valve body bolts in the correct sequence and to spec rather than corner to corner, since uneven torque can warp the separator plate and bring the same shift complaints right back. Run the adaptive relearn procedure afterward — see our adaptive relearn guide — so the control unit isn't still applying old learned shift values to the freshly rebuilt hydraulics. If you're doing a fuller repair, pair this valve body with our RE4F04A Overhaul Kit or RE4F04A Sprag Clutch.

It fits the RE4F04A as built for these model years, but Nissan made internal revisions during this span. Compare the bore layout and bolt pattern on your old valve body against this listing, or send your VIN, before you install it.
No. That fix is documented for the later RE4F04B valve body layout, not this earlier RE4F04A casting. Using it here has been linked to converter lock-up and stalling issues rather than a cleaner shift.
P0740 (torque converter clutch circuit) tied to a hunt or surge at speed, and P0745 (pressure control solenoid) tied to harsh shifting, are the two most commonly reported on this platform.
Yes. The transmission control unit stores adaptive shift values, and those should be reset after the valve body is replaced so the computer isn't still compensating for the old, worn hydraulics.
At minimum the filter and pan gasket. If you're already into the transmission for a valve body swap, our overhaul kit or sprag clutch listing covers the other wear items worth doing at the same time rather than pulling the pan twice.
