Additional Notes
- The Bristol 400 manual transmission fluid capacity falls within a range of 1.5 to 1.7 liters, which reflects a service fill specification rather than a full overhaul or dry fill figure. A range of this kind typically accounts for minor variation in fluid retention during a drain and refill procedure.
- The 1.5 to 1.7 liter spread across the Bristol 400 manual transmission suggests that technicians were expected to fill to a level indicator rather than a fixed measured volume, a common practice on transmissions of the late 1940s where dipsticks or fill plugs served as the reference point.
- Under normal use conditions, the specified check interval for manual transmission fluid is every 3,000 miles. A check interval shorter than the change interval indicates that fluid level monitoring was considered a routine part of periodic maintenance for the 400.
- The change interval under normal use conditions is set at 6,000 miles, which is double the check interval. A 6,000-mile drain cycle was a relatively frequent service cadence by mid-twentieth century standards, consistent with the mechanical tolerances and lubricant technology available during the 1947-1949 production period.
- The single use condition listed is normal, meaning the 3,000-mile check and 6,000-mile change intervals apply to standard operating circumstances without a separate severe-duty schedule specified for the Bristol 400 manual transmission.
