Rover P6

Automatic transmission fluid capacity & service interval

Rover P6 automatic transmission fluid capacity is 8 liters. Service intervals require a check every 8000 km. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Type	Specifications
3500 (1969-1977)	Use: Normal Capacity 8 liter Check 8000 km Code: 3/1
3500 S (1969-1977)	Use: Normal Capacity 8 liter Check 8000 km Code: 3/1
3500 (1968-1969)	Use: Normal Capacity 8 liter Check 8000 km Code: 3/1

The Rover P6 3500 produced from 1968-1969 carries an automatic transmission fluid capacity of 8 liters, a figure that reflects a full service fill for the transmission system.
The 1969-1977 3500 shares the same 8-liter automatic transmission fluid capacity as the earlier 1968-1969 variant, indicating no change in transmission fluid volume across the production revision.
The 3500 S from 1969-1977 also holds 8 liters of automatic transmission fluid, placing the capacity on equal footing with both 3500 configurations across the same period.
All three configurations specify a check interval of 8000 km under normal use conditions, meaning the fluid level monitoring schedule applies to standard operating circumstances rather than demanding or high-stress driving environments.
An 8-liter automatic transmission fluid capacity is a relatively substantial volume, consistent with the demands of a full automatic gearbox rather than a smaller semi-automatic or manual unit.
