Is my 2017 clutch housing waterproof/sealable?

I drive a 2017 TRD Sport DCSBMT. I want to know for sure if it's bad to use the clutch in deep water. I've researched online for awhile and learned all about the reasons that is bad in general, primarily because water (or mud etc) can get inside the clutch housing and cause the flywheel to slip (also you don't want baked-on mud all over your clutch). Some people mention they've gotten water into the clutch housing and let it dry out (or the heat of the clutch dried it out quickly) and they never saw any issues afterward. Some 4x4 vehicles have the ability to plug the clutch housing temporarily if you want, to avoid letting any liquids get inside, which means you can use the clutch in deep water. Other vehicles don't. Has anyone worked on a 3rd gen Tacoma with manual transmission that could confirm if the clutch housing is waterproof or pluggable?

Bonus points: Can anyone tell me, from an engineering point of view, why all clutch housings aren't waterproof/sealed?

Thanks much.

 

Some electronic clutches are sealed. Ours is a simple clutch and I would think the problem would be sealing the release fork. It could be done if course but it sure wouldn't be economical nor simple.

 

Ahhh, didn't think about differences between electronic vs regular clutches...good point.

 

Hey @Braves95, from what I remember you mentioned something about it, can you maybe recommend a solution?
