RE4F04A Overhaul Kit, new and ready to install. Fits the RE4F04A. Ships fast from the USA.
When a Nissan Altima, Maxima or Quest, an Infiniti I30, or a Mercury Villager with the four-speed automatic starts slipping on the upshifts, slides into gear late when cold, or leaks from the pan and case, the RE4F04A inside usually needs to come apart. This RE4F04A overhaul kit is for a full out-of-car teardown: it is listed under Transpeed code T10500A, which combines the T10502A gasket and seal overhaul kit with the T105080A friction kit and the T105081A steel kit, so one box covers the sealing and the clutch plates. The photo shows the gasket and seal portion of the set.
The RE4F04A, also catalogued by Jatco as the JF403E, is a transverse four-speed with a lockup converter. Each gear is made by applying a combination of multi-plate clutches and a band, with oil fed through the case and into rotating drums by sealing rings, and held in each piston by rubber lip seals. Frictions and steels wear and glaze with heat; seals harden and shrink with age. Once enough pressure bleeds past a seal, a clutch slips, the slip makes heat, and the heat ruins the next clutch. Replacing the gaskets, piston seals, O-rings, sealing rings, frictions and steels together resets every clutch circuit instead of curing one leak and leaving tired plates behind.
Check the fluid level hot and inspect the pan magnet and filter. Clean fluid with a stored solenoid code points to an electrical problem, not worn clutches; the RE4F04A solenoid kit covers that. Our transmission slipping diagnosis guide shows how to tell a pressure loss from glazed clutches, and a gauge on the line pressure tap, as covered in the pressure testing guide, tells you whether the pump and valve body are doing their part. Normal pressure with slipping still present means the clutch packs and seals are the job, and this kit is the right box.
This listing carries no year range. The kit is made for the RE4F04A and RE4F04V family (JF403E), commonly found in the 1993-2006 Altima, 1992-2002 Maxima, 1993-2002 Quest and Mercury Villager, and 1995-1999 Infiniti I30. TransGo splits the large-case units into A and V models through 1999 and B models from 2000, with different harness routing and valve bodies, and the small-case RE4F03 in the Sentra, 200SX and G20 is not covered. Clutch counts and plate thickness can change between revisions, so compare the pan gasket and your old plates to the kit, or send us the year, model and VIN and we will confirm it before it ships. For 2000-up B models also see our RE4F04B master rebuild kit; if you only need seals and gaskets, the RE4F04A 1993-2006 overhaul kit is the lighter option.

It is listed under Transpeed code T10500A, which is the T10502A gasket and seal overhaul kit plus the T105080A friction kit and T105081A steel kit. The photo shows the gasket and seal portion. Ask us for a packing list if you need to check a specific piece.
The large-case Nissan four-speed is found in the 1993-2006 Altima, 1992-2002 Maxima, 1993-2002 Quest and Mercury Villager, and 1995-1999 Infiniti I30, among others. Send your VIN and we will confirm.
No. Those cars use the small-case RE4F03 family, which is a different transmission.
A band is not listed in the T10500A breakdown. Inspect the old band and replace it if the lining is worn, glazed or flaking.
Use the Nissan ATF specified in your owner's manual and check the level hot after the cooler has been flushed.
The filter, the EPC solenoid (TransGo recommends a new one on every overhaul), and any worn bushings, pump parts or cracked drums you find on teardown.
