How is this? Does water somehow get into it?

I assume that with all that hydraulics inside, the transmission can get pretty hot.

All automatic transmissions (at least, all the common ones in the US market) have a vent of some kind to allow gases and vapors to escape from the transmission's casing and prevent an explosion. If you drive through water deep enough to splash in through the vent (which is often located in some strange or stupid places) or submerge it entirely, water can enter the transmission and things get worse from there. Very few vehicles have any sort of check valve or a remote relocation hose on their automatic's vent to prevent this; all the ones I know of are trucks.

Some but not all manual transmissions do have that vent, though it isn't nearly as necessary as it is for an automatic. A manual doesn't run anywhere near as hot as an automatic does in normal use, and until very recently almost all manuals used thick gear oil for lubrication instead of thin ATF, which is far less prone to vaporization and therefore needs venting less.
Even among those manuals that have such a vent, getting a little water in them isn't nearly the instant disaster that getting it into an automatic can be.

![]() The black tube is, I believe, a vent.

All the SR-4/T-5/T-56/etc Borg-Warner/Tremec transmissions have a vent, yes. This would be (in part) because they can use ATF as a lubricant instead of gear oil.
