Jensen C-V8

Manual transmission fluid capacity & service interval

Jensen C-V8 manual transmission fluid capacity ranges from 2,8 to 3,3 liters. Service intervals include checks at 6500 km and 13000 km or 6 months, and fluid changes at 51000 km. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Jensen C-V8 MK I (1962-1963) and MK II (1963-1964) share identical manual transmission fluid specifications, each calling for a 2.8-liter capacity with overdrive units included in the fill.
  • A 2.8-liter fill for the MK I and MK II represents a service fill volume, meaning the amount of fluid required during a routine drain and refill rather than a complete overhaul where residual fluid in the overdrive unit may alter the total.
  • The MK III (1965-1966) carries a noticeably larger 3.3-liter capacity for the same manual-with-overdrive configuration, a difference of 0.5 liters compared to the earlier marks.
  • The MK I and MK II share a fluid check interval of 6,500 km under normal use conditions, while the MK III specifies a longer check interval of 13,000 km or every 6 months, whichever comes first.
  • The dual-condition check interval on the MK III, combining a distance of 13,000 km with a 6-month calendar limit, means time elapsed can trigger a check even when mileage accumulation is low.
  • The MK I and MK II carry a fluid change interval of 51,000 km under normal use conditions, a relatively extended drain interval for a manual transmission of that era.
  • No fluid change interval appears in the MK III specifications, only a check interval, which distinguishes the service schedule structure of the later mark from the two earlier ones.
