Whether you have a manual or automatic transmission, the job they perform is exactly the same, the only difference is how they function to achieve that job. The job of a car's transmission is to make sure that the right amount of power goes to your wheels to drive at a given speed. To think of a transmission in simpler terms, think of a multi-speed bicycle.
When your 2008 Ford F-150 is stopped, the transmission disconnects the engine from the drive wheels so that the engine can keep idling when the wheels aren’t in motion. Transmissions also enable quick acceleration from a stop and enable the engine to run more slowly to cut down on wear while the vehicle is driving at consistent speeds.
There are many reasons one may want to upgrade their transmission. The first most obviously is if your transmission is failing. There are multiple tell-tale signs you may be in need of a replacement such as; refusal to switch gears, burning smell, noises when in neutral, slipping gears, leaking fluid, check engine light, grinding and shaking, and more. If you have any of this going on, its best to have your 2008 Ford F-150 checked out.
The other reason one may want to upgrade is for high performance needs. Your factory transmission is meant to work with a factory vehicle, not a modified performance vehicle. There are either close or wide-ratio transmissions. The difference between the two is simple and is exactly what the names imply. In a close-ratio transmission the gears are closer together. Close-ratio transmissions can handle more and lose less power when shifting gears. When shifting from gear to gear, there is a loss in RPMs, which translates to a loss of power, even if only for a split second. As the RPMs fall, the power falls, and the speed of the car also decreases. In performance vehicles and racing, that loss of speed makes a big difference. Changing from a wide-ratio to a close-ratio transmission preserves that speed and power between gears.
