Last month in Part 1 we covered first, second, third and overdrive as well as bands and clutches in an automatic transmission. This month we continue and conclude our explanation of how automatic transmissions do their thing. When You Put the Car in Park It may seem like a simple thing to lock the transmission and keep it from spinning; but there are actually some complex requirements for this mechanism: You have to be able to disengage it when the car is on a hill (the weight of the car is resting on the mechanism). You have to be able to engage the mechanism even if the lever does not line up with the gear. Once engaged, something has to prevent the lever from popping up and disengaging. The mechanism that does all this is pretty neat. Let's look at some of the parts first.
