A method of releasing a stuck vehicle with a rocking-free process which continues until the process is suppressed. The process is suppressed after a differential lock, closed at the beginning of the process, remains open for a predetermined time, or after reaching and maintaining a clutch load limit for a predetermined time, or after reaching a limit transmission gear, and maintaining the limit value for a predetermined time, or after registering the wheel rotational directions while a transmission gear engages, and after a predetermined time, in which the registered wheel rotational direction corresponds to a required direction for the gear engaged, or after a transmission gear is engaged, a transmission condition is maintained for a predetermined time, engaging a clutch for the predetermined time, a wheel speed difference limit value is reached, and the wheel speed difference remains at or falls below the speed difference limit value for the predetermined time.
