Not so....automatic transmissions use planetary gearsets rather than
parallel-shaft gearsets. The valve bodies _are_ used for ratio-changing,
though. It's only the torque converter that is a fluid coupling.

In most cases yes, though there are some transmissions that call for using
ATF. I don't remember whose.
