RE4F04A Shift Kit 1993-02, new and ready to install. Fits the RE4F04A. Ships fast from the USA.
A 1990s Nissan Maxima, Altima or Quest, Mercury Villager or Infiniti I30 with the four-speed RE4F04A that drops out of gear when it is hot at a stop, loses third after a kickdown, or keeps burning up its 3-4 clutches has a well-known hydraulic problem, and it is one a valve body repair kit was designed to solve. This is the TransGo SK RE4F04A for the 1993-2002 A and V model valve bodies. It corrects the pressure faults behind those failures and upgrades the seals that leak in the direct clutch.
The RE4F04A (Ford calls the Villager version the 4F20E) is a Jatco front-drive four-speed with solenoid-controlled shifts and an electronic pressure control solenoid. Its weak spots are well documented in TransGo's instructions. The 1-2 regulator valve sticks because its edge hits a partition in the bore and deforms it. Accumulator end plugs creep and upset line pressure, and runaway line pressure can blow out a clutch drum or damage the planetaries. Meanwhile the direct (third) clutch inner piston seal wears flat from rotating force, so third slips and the 3-4 clutches burn. The kit supplies new springs, the correct steel check balls, separator plate drilling, high-temperature low-shrink sealing rings and an upgraded direct clutch inner seal, which together fix the pressure control and the leaks.
Check fluid level and condition first. TransGo notes that the factory level is too low in cold weather and recommends a hot level about 1/4 to 3/8 in above the full mark. Then scan for codes and watch the shifts with live data; our guide on reading transmission live data explains what to look for. If you suspect a shift solenoid, test it with a meter before buying anything. A flare on the shift is a pressure or seal problem the kit can fix, while slipping in every gear usually is not; the shift flare vs slip guide shows how to tell them apart.
This listing fits the 1993-2002 RE4F04A A and V models. TransGo's application list for this kit covers the Maxima and Altima 1992-99, Quest 1993-2002, Mercury Villager 1993-2002 and Infiniti I30 1995-99, plus some later Maxima SL and Quest trims. The later B models, including the 2000-03 Maxima and 2000-06 Altima, take a different kit. To check yours, look at the internal solenoid harness. On A and V models the wires extend outside the case; on B models they stay inside. The valve body casting also differs, with A and V bodies showing two holes in the area TransGo marks and B bodies one. TransGo says to use only the kit that matches the valve body, so send us your year and VIN if you are not sure. Our related RE4F04A parts are linked below and on the RE4F04A solenoid kit page.
TransGo strongly advises a new EPC solenoid on any repair, noting these units get in trouble around 70,000 miles, so add our RE4F04A pressure control solenoid. If the clutches are already burnt, do the job with the RE4F04A overhaul kit.

Probably not. TransGo lists the 2000-06 Altima and 2000-03 Maxima as B models, which take a different kit. Check whether the internal solenoid harness extends outside the case, or send us your year and VIN.
On A and V models the internal solenoid wires extend outside the case; on B models they do not. The casting also differs, with two holes in the marked area on A and V bodies and one on B bodies.
That is one of the main complaints TransGo designed this kit to correct, along with no third after a kickdown and repeated 3-4 clutch burn-up.
Yes. TransGo recommends a new EPC solenoid on any overhaul or repair of this transmission and warns against reusing the old one.
Yes, the valve body work is done in the car. The ring and direct clutch seal upgrades need the transmission out, so do those during a rebuild.
Use the fluid your owner's manual specifies. TransGo notes the factory level is too low in cold weather and suggests a hot level about 1/4 to 3/8 in above the full mark.
