A 4×4 transmission needs to be able to handle a lot more load than many two wheel drive transmissions.
The term “4×4” generally means four wheel drive. It’s based on the idea that the vehicle has four wheels and all four can provide power to drive the vehicle.
What sets 4×4 systems apart from all wheel drive is that 4×4 systems are selectable; that is, you can choose whether to operate them in two wheel drive or four wheel drive.
Generally the transmission is the same on 4×4 and regular two wheel drive systems. The power is split behind the transmission using a transfer case. The transfer case then sends power to two separate differentials: one in the back and one in the front.
What Makes a 4×4 Transmission Different?
Of course, that doesn’t mean there aren’t some important differences between 4×4 transmissions and regular rear wheel drive transmissions. For one thing, capacity: a 4×4 transmission needs to be able to handle a lot more load than many two wheel drive transmissions.
Another is that, because these transmissions have a transfer case built into the drivetrain, diagnosis can be a lot more complex. Very often the transfer case can mimic transmission problems, which can lead to unnecessary repairs if you don’t know what to look for.
