In this post, we are going to operate our way via an automatic transmission. We are going to start with The true secret to the whole technique: planetary gearsets. Then we are going to see how the transmission is set with each other, find out how the controls do the job and talk about many of the intricacies linked to managing a transmission.
With two of these gearsets within a row, we will get the 4 ahead gears and just one reverse equipment our transmission demands. We will put the two sets of gears together in another part.
