Friction plates, steel plates and the full gasket and seal set for rebuilding the Honda MPXA five-speed automatic behind the 2.4L Accord.
If your early-1990s Accord coupe or wagon, 1992 Japan-built Accord sedan, or 1995-1997 Odyssey has started slipping on the upshifts, flaring into second, or creeping forward only after the engine revs, the clutch packs in its Honda four-speed are likely worn through. This master kit carries what a full overhaul of that unit needs: a set of friction plates, a set of steel plates, the case and cover gaskets, lip seals, O-rings, sealing rings and the small hardware shown in the photo. It is sold under the MPXA, MPWA and MPJA codes and the related four-speed codes in the same family.
Older catalog text for this kit described it as the five-speed behind the 2.4L Accord. The code list says otherwise. MPXA, MPWA, MPJA, MPOA, APXA, A6VA, MP1A, BOYA and PX4B all belong to Honda's 4-speed, 3-shaft automatic of the 1990s. The 2003-2007 Accord 2.4L five-speed is a different transmission with different clutch packs, so this kit will not rebuild it.
Honda's automatic is built like a manual gearbox. Gears sit in constant mesh on three parallel shafts, and each ratio is engaged by its own hydraulic clutch pack rather than by bands and planetary gearsets. Each gear holds only as well as its own clutch. A worn second clutch shows up as a second-gear flare while third and fourth can still feel normal. Renewing every friction and steel together, with fresh seals on the clutch pistons and sealing rings on the shafts, gives every gear its full clamping force back.
Not every symptom is clutch wear. Sonnax links converter charge regulator valve wear in these units to overheated converter fluid, low cooler flow and lockup lining failure, which a rebuild will not fix if the valve body is ignored.
Check the fluid warm on the dipstick. Burnt fluid with a slip tied to one gear points at that gear's clutch. A clean red sample with an erratic shift points to a solenoid, sensor or valve problem instead. Our flare versus slip guide helps you tell the two apart, and if shudder is the main complaint, work through our converter shudder diagnosis before you commit to a teardown.
Based on the code-to-vehicle map published for this kit family, the codes in the title cover the 1993 Accord coupe and wagon (MPXA), the 1992 Accord sedan built in Japan (MPWA) and the 1995-1997 Odyssey and its Isuzu Oasis twin (MPJA). The listing also names MPOA (1994-97 Accord), APXA, A6VA (1997 Acura 2.2CL), MP1A (1992-96 Prelude), BOYA (1996-97 Accord sedan) and PX4B (1990 Accord). Honda stamped the code on the case, so read it before ordering and send us the code or your year and VIN if you want a check. Clutch counts differ between some codes, which is why the code matters more than the model name. A frictions-and-steels set for the same family is our MPOA frictions and steels kit, and more overhaul kits are in rebuild kits.

No. Despite older catalog wording, the codes this kit is built for (MPXA, MPWA, MPJA and related) are Honda's 1990s 4-speed 3-shaft automatic. The 2003-2007 Accord 2.4L five-speed uses different clutch packs.
Honda stamps a four-letter code on the transmission case near the top of the bellhousing area. Read it before ordering, or send us your year and VIN and we will check it for you.
Friction plates, steel plates, case and cover gaskets, lip seals, O-rings, sealing rings and small hardware as pictured. The filter, bushings and hard parts are not included.
Honda ATF DW-1, the current Honda automatic fluid that replaced the earlier Honda ATF. Check the level warm on the dipstick after a test drive.
The 1995-1997 Odyssey uses the MPJA code, which this kit is listed for. Confirm the stamp on your case matches before ordering.
