The 2nd gear clutch pack is the most common wear point. Friction disc glazing causes harsh 1-2 shift or slip under acceleration.
Symptoms: Harsh or delayed 1-2 upshift, RPM flare under light throttle, DTC P0732 (gear 2 incorrect ratio)
Honda A24A is sensitive to fluid condition. Neglected intervals cause varnish buildup in valve body passages, leading to shift quality issues across all gears.
Symptoms: Dark or burnt-smelling ATF, sluggish shifts, engagement clunk when selecting Drive or Reverse
The throttle and shift control cables stretch with age, causing misalignment between gear selector position and actual engagement.
Symptoms: Gear indicator mismatch, neutral bump when downshifting, difficulty finding Park
A24A rebuild begins with complete teardown and ultrasonic valve body cleaning. All clutch packs are measured and replaced with upgraded frictions. Sealing rings, thrust washers, and bearing sets are replaced. Torque converter is rebuilt or exchanged. Valve body solenoids are tested and replaced if out-of-spec.
Change Honda-spec ATF every 30,000 miles. Do not substitute Dexron — the A24A friction material requires Honda ATF chemistry for proper clutch engagement. Never overfill; check level with engine warm and idling in Park.
The A24A was used in 1990–1997 Honda Accords with the F22 four-cylinder engine and some early Acura Legend applications.
No. Honda ATF-Z1 or a Honda-compatible ATF is required. Dexron can cause clutch slip and premature wear in Honda transaxles.
A standard rebuild takes 2–3 days at Chicago Transmission, including valve body reconditioning and torque converter service.
Harsh or slipping 2nd gear shifts, burnt ATF smell, DTC codes P0732 or P0740, or fluid that looks dark brown or black.
Fluid service runs $129. A full rebuild ranges $1,450–$1,900 depending on worn components found during teardown.
