Honda CRX II, ED8, ED9 (USA / CAN)

Automatic transmission fluid capacity & service interval

Honda CRX II, ED8, ED9 (USA / CAN) automatic transmission fluid capacity ranges from 2,4 to 5,4 liters. Service intervals occur every 30000 miles or 24 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
CRX II 1.5 (1988-1991)
  • Use: Normal
  • Capacity 5,4 liter (Initial fill)
  • Capacity 2,4 liter (Service fill)
  • Change 30000 miles/ 24 months
  • Code: ML4A 4/1
CRX II 1.6 Si (1988-1991)
  • Use: Normal
  • Capacity 5,4 liter (Initial fill)
  • Capacity 2,4 liter (Service fill)
  • Change 30000 miles/ 24 months
  • Code: ML4A 4/1

Additional Notes

  • Both the CRX II 1.5 and 1.6 Si share an initial fill capacity of 5.4 liters, which represents the total fluid volume required when filling a dry automatic transaxle from empty, such as after a complete overhaul or unit replacement.
  • The service fill capacity of 2.4 liters applies to routine fluid changes on both configurations, reflecting only the volume that drains when the drain plug is removed, leaving residual fluid in the torque converter and valve body.
  • The difference between the 5.4-liter initial fill and the 2.4-liter service fill means that roughly 3 liters of automatic transmission fluid remains in the transaxle during a standard drain-and-fill service, which is a normal characteristic of automatic transaxle designs where the torque converter retains fluid.
  • The Honda CRX II ED8/ED9 automatic transaxle service interval is set at 30,000 miles or 24 months under normal use conditions, whichever comes first, applying equally to both the 1.5 and 1.6 Si variants.
  • The 24-month time limit paired with the 30,000-mile mileage threshold means that lower-mileage vehicles still reach a fluid change interval based on elapsed time alone, independent of distance traveled.
  • The specifications cover the 1988-1991 model years for both engine variants, with no differentiation in fluid capacity or change interval across that four-year production span.
