Additional Notes

  • The BMW 7 Series E65 (USA) automatic transmission fluid capacity is listed as a range of 9.4 to 10 liters across all three engine variants, which reflects the typical variation between a partial service fill and a full system capacity including the torque converter and cooler lines.
  • The 745i covers model years 2001-2005, the 750i covers 2005-2008, and the 760i covers 2002-2008, yet all three share an identical fluid capacity range of 9.4 to 10 liters.
  • A 100,000-mile change interval is specified under normal use conditions for the 745i, indicating the transmission fluid is not classified as a lifetime fill despite the extended interval.
  • The 750i carries the same 100,000-mile normal-use change interval as the 745i, meaning the engine displacement difference between the two variants does not affect the service schedule for the automatic transmission.
  • The 760i, which uses a V12 engine rather than the V8 found in the 745i and 750i, shares the same 9.4 to 10 liter capacity range and 100,000-mile normal-use interval, suggesting the transmission unit itself is consistent across the lineup regardless of engine configuration.
  • A 100,000-mile interval under normal use is considerably longer than many conventional automatic transmission service schedules, which often fall in the 30,000 to 60,000-mile range, placing the E65 specification at the extended end of typical manufacturer recommendations.
