Additional Notes

  • The Renault Buses (EU) PR 100-2, covering model years 1980-1995, carries two distinct automatic transmission fluid capacities: 19 liters and 12 liters. In automatic transmission service, a larger figure typically represents a full overhaul or dry fill, while the smaller figure represents a service fill after a fluid change where residual fluid remains in the torque converter.
  • The PR 180-2, spanning 1980-1994, shares the same 19-liter and 12-liter capacity split seen in the PR 100-2, suggesting both transmission configurations follow a comparable fill structure under normal use conditions.
  • The R 312, introduced in 1986 and running through 1996, carries notably higher automatic transmission fluid capacities than either the PR 100-2 or PR 180-2. A 25-liter figure and a 17-liter figure are both listed for normal use, pointing to a larger transmission assembly in the R 312 platform.
  • The 25-liter capacity on the Renault Buses (EU) R 312 is the highest automatic transmission fluid value across all three bus types in the specifications, indicating a substantially larger fluid volume requirement for a full overhaul fill on that model.
  • All capacity entries across the PR 100-2, PR 180-2, and R 312 are designated for normal use conditions, meaning none of the listed figures are tied to severe-duty or extended-interval service distinctions within the specifications.
  • The PR 180-2 has three separate 12-liter entries under normal use conditions, while the PR 100-2 carries two. Both models also carry two 19-liter entries each, reflecting multiple fill points or procedures documented at the same capacity level.
