RE4F04A Overhaul Kit 1991-2003, new and ready to install. Fits the RE4F04A. Ships fast from the USA.
When a Nissan Maxima, Altima or Quest, an Infiniti I30 or a Mercury Villager with the four-speed RE4F04A starts dripping from the pan, falls out of gear at a stop once it is hot, or loses third after a kickdown, the problem is very often a hardened seal rather than a burnt-out clutch. This RE4F04A overhaul kit is the soft-parts set for resealing the transmission during a teardown: new gaskets, lip seals, O-rings and the plastic and Teflon sealing rings that feed the rotating clutch drums. It is a new kit catalogued as T83002B and K63900G, built by Toledo Trans-Kit or Precision International depending on stock.
The RE4F04A is Jatco's large-case front-drive four-speed. Its clutches are applied by pistons sealed with rubber lip seals, and the oil that reaches those pistons has to pass from the stationary case into spinning drums through sealing rings. As the unit ages, the rubber shrinks and hardens and the rings wear their grooves, so apply pressure bleeds off before it can clamp the plates. TransGo singles out the third (direct) clutch inner piston seal on this transmission: it leaks, wears or opens up from rotating force, and the result is a car that falls out of gear at a stop when hot or has no third after a 3-2 or 4-2 kickdown. Resealing every circuit at once is how you stop chasing those leaks one at a time.
If the frictions are glazed or burnt, a seal kit alone will leave you with a sealed transmission that still slips. In that case our RE4F04A master rebuild kit adds the friction plates.
Check the fluid first. Clean red fluid with no lining on the magnet points to a sealing problem that this kit fixes; dark, burnt fluid with debris means the clutches are worn too. A pressure gauge on the line tap tells you whether a single circuit is leaking, and our transmission pressure testing guide explains how to read the numbers by range. If the car slips under load rather than dropping out of gear, compare what you see against our slipping diagnosis guide before deciding between a reseal and a full rebuild.
This kit is listed for the RE4F04A, RE4F04V and the 4F20E version used in the Villager. TransGo's identification sheet groups the A and V units as the 1992-99 Maxima, 1993-99 Altima, 1993-2002 Quest, 1995-99 Infiniti I30 and 1993-2002 Mercury Villager, with some later Maxima SL and Quest trims. On A and V transmissions the internal solenoid wires come out through the case; on the later RE4F04B (2000-up Maxima, 2000-06 Altima, I35 and others) the harness stays inside, and the B may need a different kit. The small-case RE4F03 in the Sentra and 200SX is a different transmission. Look at the solenoid wiring before you order, and send us your year, make, model and VIN if you are not sure. More rebuild parts are in our rebuild kits category.

No. It is a gasket and seal kit only. Frictions, steels, filter, band, bushings and hard parts are not included. Choose the master rebuild kit if your clutches are worn.
Not reliably. The kit is listed for RE4F04A, RE4F04V and 4F20E units. On A and V models the solenoid wires exit the case; on B models the harness stays inside. If yours is a B unit, send us your VIN so we can check before you order.
TransGo lists the 1992-99 Maxima, 1993-99 Altima, 1993-2002 Quest, 1995-99 Infiniti I30 and 1993-2002 Mercury Villager as A and V applications, plus some later Maxima SL and Quest trims.
Replace the EPC solenoid, the filter and any friction plates that are glazed or burnt, and flush the cooler. TransGo recommends a new EPC solenoid on every overhaul because these units are sensitive to line pressure control.
A common cause is a leaking third (direct) clutch inner piston seal. As the seal hardens or opens up from rotating force, pressure leaks away when the fluid thins out hot. A full reseal with this kit addresses it.
