Abstract

A method to prevent chain jump in a drivetrain of a four-wheel drive vehicle including receiving sensed vehicle parameters from sensors in the four-wheel drive vehicle, generating transfer case chain-jump parameters based on the sensed vehicle parameters and sending a command signal to initiate disengagement of a clutch pack in a transfer case of the drivetrain responsive to the generated transfer case chain-jump parameters.
