BMW E60 automatic gearbox oil change
E60: what oil does the automatic gearbox (ZF 6HP26) take and how much?
According to the service data, the 530d gearbox (GA6HP26Z) takes Shell M-1375.4 oil, part number 88220142516. According to the instructions the gearbox holds 9-10 litres of oil. The oil is also available in smaller quantities than the 20-litre canister.
Does the E60 automatic gearbox oil need changing and when?
The manufacturer gives no change interval, and some consider the oil lifetime. If an interval is wanted, 100 000-150 000 km is better than 200 000 km. Opinions are also divided on whether the oil is worth changing only in a car with over 200 000 km.
Does the automatic gearbox oil need flushing when changing it?
Opinions on that are conflicting. Without flushing, about half of the oil remains old, so flushing is recommended. On the other hand, if the oil is changed often and with the same type, flushing is not considered necessary. The filter is always replaced with a new one.
Do the automatic gearbox adaptations need resetting after an oil change?
Adaptations are correction values learned by the gearbox that compensate for wear. They are reset with a diagnostic tool, not with a software update. On a worn gearbox, resetting can worsen performance, so it should not be done without replacing a mechanical part. The values settle by driving.
