Frictions, steels, gaskets and seals to rebuild the Honda MPOA four-speed automatic in the 1990-1997 Accord, 1992-2001 Prelude and 1992-1994 Vigor.
A 1990-1997 Honda Accord, 1992-2001 Prelude or 1992-1994 Acura Vigor automatic that flares between first and second, slips hot, or has gone to no forward drive with black fluid needs its clutch packs and seals replaced. This master rebuild kit (manufacturer part number AHM-QMP-GN02440) carries the friction plates, steel plates and full gasket and seal set for the Honda four-speed sold under the MPOA, APXA, MPXA and related case codes.
Honda's automatics of this era do not use planetary gearsets the way most four-speeds do. They work like a manual gearbox with constant-mesh gears on parallel shafts, and each gear is selected by its own hydraulic clutch pack. Parts suppliers group the MPOA family as the Honda 4-speed, 3-shaft unit. Because every ratio has a dedicated clutch, the condition of each pack decides whether that gear holds. When the second clutch glazes, second gear is the first to go, while the other gears may still feel normal. This kit replaces every friction and steel and the seals and gaskets that keep apply pressure on the pistons, so each gear clutch clamps fully again.
Check fluid level with the engine warm and look at the condition on the dipstick. Clean red fluid and a single erratic shift point toward a solenoid, sensor or valve problem, not a teardown. Burnt fluid and a slip tied to one gear point at the clutch pack for that gear. Our shift flare vs slip guide explains how to tell a timing flare from a true slip, and the ATF color and smell chart helps judge the fluid. If the shudder is the main complaint, read our torque converter shudder guide before you commit, since the converter and its charge pressure circuit can cause the same feel.
The listing covers the 1990-1997 Accord 2.2L and 2.7L (CB7 and CD5 chassis), the 1992-2001 Prelude 2.2L and 2.3L and the 1992-1994 Acura Vigor 2.5L. The kit is built for case codes AOYA, MPOA, MPWA, MPXA, PX4B, APXA, A6VA, BOYA, MP1A and MPJA. Honda changed units within a model year, and supplier catalogs split the codes by body style and year (for example APX4 on 1991-1992 Accords and MPOA on 1994-1997 wagons), so read the code stamped on the case instead of going by model year. If your code is not on that list, send us the code or the VIN before ordering. Other Honda units are in our rebuild kits collection, including the MPXA, MPWA and MPJA master kit for the Accord and CR-V.

The code is stamped on the case, on the pad near the bellhousing. Read it there instead of going by the model year, because Honda used different codes in the same year depending on body style and engine.
The listing includes the Accord 2.7L CD5 range. Check that your case code is one of the ten on the list - AOYA, MPOA, MPWA, MPXA, PX4B, APXA, A6VA, BOYA, MP1A or MPJA - or send us the VIN.
Each gear has its own clutch pack, and the second clutch takes the hardest work on every launch and 1-2 shift. When it glazes you get a flare between first and second while the other gears still feel normal.
No. The kit carries frictions, steels and the gasket and seal set. The filter, hard parts, valve body and torque converter are not included and should be ordered or inspected separately.
Honda ATF DW-1. Honda units are sensitive to fluid type, and a generic multi-vehicle fluid can change shift feel and clutch wear. Check the level warm after the first drive.
