Impressive work!!

Thanks Andy.

Simply put, an auto trans is a hydraulic unit that activates a clutchpack or a band. When this occurs, it puts certain geartrain parts in a bind (locks them solid). This causes a different drivetrain part to rotate, thus changing gear ratios.

Everything else inside relates to the timing of these mechanical (via hydraulic pressure) parts to control the exact time it happens, and releases.
