Additional Notes
- The Wolseley 18/85 automatic transaxle carries a service fill capacity of 4.4 liters, meaning a routine fluid change without full disassembly replaces only a portion of the total fluid volume held in the system.
- The total fluid capacity of the 18/85 automatic transaxle reaches 7.4 liters, a figure that applies when the unit is fully drained during an overhaul or complete rebuild procedure.
- The gap between the 4.4-liter service fill and the 7.4-liter total capacity in the 18/85 automatic reflects fluid retained in the torque converter and internal passages during a standard drain, which is typical behavior for automatic transaxle designs of the era.
- The Wolseley Six automatic, covering 1972-1975, shares the same 7.4-liter total capacity as the earlier 18/85 unit, indicating a comparable overall fluid volume for the transaxle assembly at full overhaul.
- A dedicated torque converter capacity of 3 liters is specified separately for the Six automatic, identifying the converter as a distinct fluid reservoir within the transaxle system rather than a figure absorbed into a general total.
- Both the 18/85 and Six automatic configurations are noted as transaxle arrangements, meaning the transmission and final drive share a common fluid sump rather than operating as separate units with independent fluid requirements.
- All capacity figures across both configurations are listed under normal use conditions, with no separate severe-duty interval or capacity distinction present in the specifications.
