The transmission module is driveably connected to the input source and a creeper module is driveably engaged with the drive member of the transmission module. The creeper module is detachably mounted to the casing of the transmission module. An output assembly is in driving engagement with the creeper module and a control interface is configured to selectively engage the creeper module to transform the speed of the drive member to a reduced speed of the output member.
