A free mod for American Truck Simulator, by MxmOvrDrv MxmOvrDrvMods.

AIO Engines Chassis Transmissions is a free-to-download mod that allows you to easily browse through all of the available engine, transmission, and chassis combinations for your truck.

All of the combinations are sorted by power and fuel capacity, so you don’t have to worry about getting stuck with the most expensive or the least powerful option. You can also sort the combinations by price, model, or type, so you can easily find the one that best suits your vehicle.

Once you’ve chosen the right combination, you can download the relevant files and install them into your truck.

The mod is very easy to use, so you won’t have any trouble getting started.
