730d740d
Is the E38's ZF 5HP24 automatic durable?
Automatic gearboxes do not usually fail, although individual faults occur. The 5HP24's typical fault is a failing A drum (a clutch part inside the gearbox). A new reinforced part is available for it.
Which automatic does the E38 diesel have?
The 730d has the ZF 5HP24. The 740d has the larger ZF 5HP30 (A5S 560Z), which is different from the 530d's GM gearbox. The number 560 indicates the gearbox's torque capacity, the standard value being 560 Nm. In older models the oil is not meant to be lifetime.
