Bedford Astramax
Automatic transmission fluid capacity & service interval
Bedford Astramax uses automatic transmission fluid with a capacity range of 6,3 to 7 liters. Service intervals require checks every 15000 km or 12 months. The data covers 5 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Bedford Astramax automatic transmission fluid specifications cover an integrated transaxle unit across all listed engine variants, meaning the fluid capacity figure represents the combined gearbox and differential assembly rather than a standalone gearbox.
- The 1.3-litre variant (1986-1989) carries a transaxle capacity of 6.3 litres, which is the lowest figure across all listed configurations and reflects the smaller drivetrain package paired with the 1.3 engine.
- All 1.6-litre variants, including the standard 1.6 (1986-1990), the 1.6 D (1986-1989), and the later 1.6i (1991-1993), share an identical transaxle capacity of 7 litres, indicating a common automatic transaxle unit across those engine types despite differences in fuel delivery and production period.
- The 1.7 D (1989-1993) also carries a 7-litre transaxle capacity, placing the diesel variant in line with the 1.6-litre petrol and diesel configurations rather than requiring a distinct fluid volume.
- All five configurations share a uniform service check interval of 15,000 km or 12 months under normal use conditions, whichever comes first. The 12-month time limit means the interval is not solely mileage-dependent, which is relevant for lower-mileage vehicles that may not reach the distance threshold within a year.
- The interval specification is expressed as a fluid level check rather than a full drain-and-refill service, which is a meaningful distinction. A check interval monitors fluid condition and level without necessarily requiring a complete fluid exchange at each visit.
- The 1.6 D and 1.7 D are diesel-engined variants fitted with automatic transaxles. Diesel engines generally produce higher torque at lower revs compared to equivalent petrol units, which can place different thermal and mechanical demands on automatic transmission fluid over time.
- The overlap in production years between the 1.6 (ending 1990) and the 1.6i (starting 1991) reflects a transition from carburetted to fuel-injected petrol engine specification, yet the transaxle capacity and service interval remain unchanged between the two, pointing to continuity in the automatic transmission unit itself.
