Systems and methods to process vehicle operation data are described. A data module associated with a vehicle can collect operation data relating to the gear operation of the vehicle. The data module can process the operation data to identify a top gear of the vehicle and determine the current gear at which the vehicle is operating. The data module can process the operation data to determine an amount of time that the vehicle operates in top gear. The data module can provide the data to an operator of the vehicle, or to a remote management center, for storage and/or further processing.
