A vehicle drivetrain assembly operable in a first mode and a second mode. The vehicle drivetrain assembly comprises: a drive unit arranged to generate power to drive a vehicle (1); an automatic transmission comprising a torque converter and operatively coupled to the drive unit to receive the power; and a control system comprising one or more controllers (11), the control system being arranged to adjustably limit the maximum torque delivered to the transmission from the drive unit. When the automatic transmission is in first gear with the torque converter stalled, the control system limits the maximum torque to a first level when the vehicle drivetrain assembly is in the first mode and to a second level when the vehicle drivetrain assembly is in the second mode, the first level being lower than the second level. The system may also have a third and fourth level of torque limit and can impose less torque reduction during gear changes.
