Renault Celtis

Automatic transmission fluid capacity & service interval

Renault Celtis automatic transmission fluid capacity is 65 liters. Service intervals include checking every 10 hours and changing every 1000 hours. The data covers 4 configurations.

Additional Notes

  • All four Renault Celtis variants covered here — the 426, 436, 446, and 456 — share an identical transmission/hydraulic system fluid capacity of 65 liters, indicating a combined transmission and hydraulic circuit rather than separate, independently filled reservoirs.
  • A 65-liter capacity is notably large relative to typical automotive transmission systems, which reflects the dual-purpose nature of a shared transmission/hydraulic system common in agricultural tractors, where hydraulic implements and the transmission draw from the same fluid volume.
  • The check interval for all four variants is set at 10 hours of operation under normal use conditions, a very short interval by general mechanical standards, consistent with the high-load, variable-duty cycles associated with tractor field work.
  • The fluid change interval across all listed variants is 1000 hours of operation under normal use conditions, a time-based measurement in engine hours rather than distance, which is standard practice for agricultural machinery where odometer mileage is not a meaningful service metric.
  • The Celtis 426 is identified by model codes M3612DB, 3612DA, and 3611DB, the 436 by M3622DB, 3622DA, and 3621DB, the 446 by M3632DB, 3632DA, and 3631DB, and the 456 by M3642DB and 3642DA, indicating multiple sub-configurations exist within each variant, all sharing the same 65-liter capacity and service intervals.
  • The ratio between the check interval and the change interval is 1:100, meaning fluid level is verified 100 times for every full drain-and-refill cycle, reflecting how critical maintaining correct fluid volume is throughout the extended service life of a shared transmission/hydraulic system.
