Mitsubishi Galant (EU)

Automatic transmission fluid capacity & service interval

Mitsubishi Galant (EU) automatic transmission fluid capacity ranges from 5,5 to 6,4 liters. Service intervals include checks at 5000 and 20000 km, and changes at 40000 and 80000 km. The data covers 10 configurations.

Additional Notes

  • The earliest Mitsubishi Galant (EU) automatic transmission configurations, covering the A112 and A115 units fitted to the 1600 and 2000 variants from 1973-1976, share an identical fluid capacity of 5.5 liters and a check interval of 5000 km, which is notably shorter than the 20000 km check interval specified for all later transmission generations in this range.
  • The 1973-1976 A112 and A115 transmissions also carry a change interval of 40000 km under normal use conditions, a figure that matches the severe-use change interval applied to the later A121, A123, A161, and A163/164 units, illustrating how service expectations shifted between generations.
  • From 1976 onward, the A121 and A123 transmissions introduced for the 1600 and 2000 engine variants both specify a fluid capacity of 6.4 liters, an increase of 0.9 liters over the earlier 5.5-liter units. A larger total fluid volume generally reflects a greater sump capacity or additional fluid circuits within the transmission assembly.
  • The A121 and A123 units from 1976-1980 carry a normal-use change interval of 80000 km, double the 40000 km interval of the 1973-1976 transmissions. Under severe use conditions, the change interval for the same A121 and A123 units is halved to 40000 km, while the fluid capacity of 6.4 liters remains unchanged regardless of use condition.
  • The A161 and A163/164 transmissions, introduced for the 1980-1984 model years across both the 1600 and 2000 engine variants, specify a fluid capacity of 6.2 liters. This is a slight reduction from the 6.4-liter figure of the preceding A121 and A123 units, despite covering the same engine displacement categories.
  • For the 1980-1984 A161 and A163/164 transmissions, the normal-use change interval remains at 80000 km, consistent with the 1976-1980 generation. Severe-use operation again reduces the change interval to 40000 km, with the 6.2-liter capacity figure applying equally to both use conditions.
  • The A163 and A164 designations are grouped together as a single specification entry for the Galant 2000 from 1980-1984, indicating that both transmission variants share the same fluid capacity of 6.2 liters and identical service intervals under both normal and severe use conditions.
