Master overhaul set for the Ford and Mazda CD4E four-speed: friction plates, steels, bonded pistons, pump bushing, seals and gaskets for a bench rebuild.
A Ford Escape, Mazda Tribute, Mercury Mariner Hybrid, Mazda 626 or Ford Probe with the CD4E that slips into third or fourth, flares between shifts or has gone dark and burnt on the dipstick usually needs more than seals. This master rebuild kit is built for that job: friction plates and steels for the clutch packs, bonded pistons, the pump bushing, and the full seal, O-ring and gasket set, cross-referenced to OE kit numbers KP7000V, KP7000A, 112901 and 112903.
The CD4E is the four-speed transaxle Ford and Mazda launched together in 1994 in the Probe and 626, which Mazda catalogs as the LA4A-EL. It shifts by applying clutch packs and a band, with a low one-way clutch holding first. Each clutch is applied by a piston, and on this unit the pistons are bonded, with the rubber lip molded to the metal. Once those lips harden or split, apply pressure leaks past them, the pack slips, and the frictions cook. A plain gasket and seal kit does not address that. This kit replaces the frictions, the steels and the bonded pistons together, and adds the pump bushing, so the clutches, their apply pistons and the pump that feeds them are all renewed in the same rebuild.
Before the unit comes out, pressure test it. A line pressure gauge at idle tells you a lot: low pressure with delayed engagement points to a worn pump or filter, while pressure that does not rise with engine load points to the pressure regulator valve. Our line pressure testing guide covers the hookup. If the fluid is burnt and the pan has clutch material, the packs are worn and this kit is the right repair. If pressures are off but the fluid is clean, the valve body may be the root cause, and you will want to fix that at the same time so the new clutches are not burned again. The converter hub and pump bushing wear guide explains why the pump bushing matters on a unit that has run hot.
The listing covers the Ford Escape 2001-2004 2.0L, 2005-2008 2.3L and 2001-2008 3.0L, Escape Hybrid 2005-2008 2.3L, Mercury Mariner Hybrid 2006-2008 and Mazda Tribute 2001-2008 in 2.0L, 2.3L and 3.0L. It also covers the Ford Probe 1994-1997 2.0L and 2.5L, Mazda 626 1994-2002 2.0L and 2.5L and Mazda MX-6 1994-1997. Overhaul numbers quoted against the same unit include F3RZ-7A098A (Ford) and FW50-21-500 (Mazda). Ford changed CD4E internals over the years, so match your case tag, and send your year and VIN if you want us to check it. Hard parts for this unit are in our rebuild kit category.
Pay attention to the low/reverse clutch stack-up, because it changed. Through 2006 the CD4E used a low roller clutch with one waved cushion spring and a spacer plate. Beginning in late 2006, Ford phased in a mechanical diode, which adds a second, thinner waved spring between the selective steel and the diode and drops the spacer plate. Build the pack to match the parts in your case. Set clearance with the selective steel, and check that the one-way clutch inner race turns clockwise once installed.
Inspect the band and servo while the unit is apart; band breakage has been a CD4E problem even on late models. Check the drums too, and replace a worn forward and coast clutch drum rather than putting new frictions in a damaged one. If line pressure tested wrong, put in the CD4E valve body with solenoid block. Replace the torque converter, flush the cooler and lines, and air-check every clutch circuit before the pump goes on. Fill with MERCON V on Escape, Tribute and Mariner, and check the owner's manual for the correct fluid on the 1990s cars.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. A gasket and seal kit stops at seals and gaskets. This master kit adds friction plates, steels, bonded pistons and the pump bushing, so the clutch packs and their apply pistons are renewed as well.
The listing covers 1994-2008 applications. Ford changed the low/reverse stack-up in late 2006 when it moved from a roller clutch to a mechanical diode, so reuse the wave springs and spacer that match your case and set clearance with the selective steel.
Escape, Tribute and Mariner call for MERCON V. Check the owner's manual for the correct fluid on Probe, 626 and MX-6 models.
Yes. A CD4E that burned its clutches has pushed friction material through the converter. Reusing it sends that debris back into the new frictions.
The listed contents are frictions, steels, bonded pistons, the pump bushing, seals, O-rings and gaskets. Inspect the band, filter and drums and replace them separately as needed.
