Additional Notes

  • The Honda Prelude 2.2 VTEC manual transaxle carries an initial fill capacity of 2.0–2.2 liters, which represents the volume required when filling a dry or fully drained unit, such as after a complete overhaul or transaxle replacement.
  • Service fill capacity is rated at 1.9–2.1 liters across all six configurations, reflecting the slightly lower volume returned to the transaxle during a routine fluid change, where residual fluid remains in passages and components after draining.
  • The initial fill figure exceeds the service fill figure by approximately 0.1–0.3 liters, a difference consistent with the volume of fluid that cannot be fully expelled through a standard gravity drain.
  • Canadian-market specifications for both the standard 2.2 VTEC and the SH trim set the normal-use change interval at 30,000 miles or 24 months, whichever comes first.
  • USA-market specifications for both the 2.2 VTEC and the 2.2 VTEC SH under normal use carry a significantly extended change interval of 90,000 miles or 72 months, a figure three times longer than the Canadian normal-use schedule.
  • Under severe-use conditions, the USA-market interval for both the standard and SH configurations drops to 30,000 miles or 24 months, aligning with the Canadian normal-use schedule rather than the extended USA normal-use interval.
  • Severe use is a classification that typically accounts for operating conditions such as frequent towing, repeated short trips, extreme temperatures, or sustained high-load driving, all of which accelerate fluid degradation and justify the shortened 30,000-mile interval.
  • Fluid capacities are identical across the standard 2.2 VTEC and the 2.2 VTEC SH trim for both markets, indicating no transaxle volume difference between the two trim levels despite the SH designation denoting a distinct Active Torque Transfer System configuration.
