Additional Notes

  • The Datsun (Nissan) Fairlady SP(L) 311 carries a manual transmission fluid capacity of 2.2 liters, while the larger-engined SR(L) 311 requires 2.6 liters, reflecting the difference in gearbox size between the 1600 and 2000 variants.
  • Both the SP(L) 311 and SR(L) 311 share an initial service drain interval of 1,000 km, a first-change specification intended to flush metal particles generated during the mechanical break-in period of a new or rebuilt transmission.
  • Under normal use conditions, the manual transmission fluid check interval for both the SP(L) 311 and SR(L) 311 is set at 5,000 km, with a full fluid change scheduled at 40,000 km.
  • The 400 ml difference in capacity between the SP(L) 311 at 2.2 liters and the SR(L) 311 at 2.6 liters is a meaningful distinction when performing a service fill, as underfilling a transmission can lead to inadequate lubrication of the gear sets and bearings.
  • The 1,000 km initial service interval listed for both Fairlady variants applies exclusively to the first fluid change and does not repeat in the normal service schedule, which resumes at the 40,000 km change interval.
