Mitsubishi Sigma (EU)

Automatic transmission fluid capacity & service interval

Mitsubishi Sigma (EU) requires Automatic transmission fluid with a capacity of 7,5 liters. Service intervals include checking every 20000 km and changing every 40000 km 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
Sigma 3.0 (1991-1996)
  • Use: Normal
  • Capacity 7,5 liter
  • Check 20000 km
  • Change 40000 km/ 24 months
  • Code: 4/1
Sigma 3.0 24V (1991-1996)
  • Use: Normal
  • Capacity 7,5 liter
  • Check 20000 km
  • Change 40000 km/ 24 months
  • Code: 4/1

Additional Notes

  • The Mitsubishi Sigma (EU) automatic transaxle holds 7.5 liters of fluid, a figure that reflects a full system fill rather than a simple drain-and-refill service, since a complete overhaul or dry fill of an automatic transaxle accounts for fluid retained in the torque converter and valve body circuits.
  • Both the 3.0 and 3.0 24V variants share an identical 7.5-liter capacity, meaning the additional valvetrain complexity of the 24-valve engine does not alter the transmission fluid volume requirement.
  • The fluid check interval is set at 20,000 km under normal use conditions, placing a routine inspection at the halfway point before a full fluid change is due.
  • The change interval is defined as 40,000 km or 24 months, whichever comes first, meaning time elapsed is treated as an equally valid trigger as distance traveled under normal use conditions.
  • Both the 3.0 and 3.0 24V specifications carry the same 40,000 km/24-month change interval across the 1991-1996 model range, indicating no differentiation in service scheduling between the two engine variants.
