Additional Notes

  • The Bristol 401 manual transmission holds between 1.5 and 1.7 liters of fluid, a range that reflects a service fill tolerance rather than a fixed overhaul volume, meaning the actual quantity seated in the unit can vary slightly depending on the fill method and operating temperature at the time of service.
  • Under normal use conditions, the specified check interval for the Bristol 401 manual transmission fluid is every 3,000 miles, which places routine monitoring at half the frequency of a full fluid change.
  • The change interval under normal use conditions is set at 6,000 miles, doubling the check interval and establishing a relatively short drain cycle by mid-century automotive standards.
