Automatic transmission fluid capacity & service interval
BMW 1500, 1502, 1600, 1602, 1802, 2002, E10/E20 (USA) models require automatic transmission fluid with a capacity range of 1,6 to 5,2 liters. Service intervals include checking every 4000 miles or 6 months and changing every 20000 miles. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| 1802 (1971-1975) |

Additional Notes
- The BMW 1802 and 2002/2002A share identical automatic transmission fluid capacities across all three fill categories: 5.2 liters when the oil cooler circuit is included, 4.65 liters for the initial fill, and 1.6 liters for a refill.
- The 5.2-liter figure represents the total system volume, accounting for fluid held within the oil cooler and its connecting lines in addition to the transmission itself.
- The 4.65-liter initial fill capacity reflects the amount of fluid introduced into a dry transmission during assembly or after a complete overhaul, before the cooler circuit is primed.
- The 1.6-liter refill value is notably lower than the initial fill, indicating the volume displaced during a routine drain where residual fluid remains in the torque converter and cooler passages.
- Both the 1802 (1971-1975) and the 2002/2002A (1968-1975) carry a fluid level check interval of every 4,000 miles or 6 months under normal use conditions, whichever comes first.
- The change interval for both configurations is set at 20,000 miles under normal use, applying to the 1.6-liter refill quantity rather than the full system volume.
