Transmission very notchy after rainfall

[lolcantturn]

Transmission seems exceptionally notchy today after driving through very very heavy downpour with lots of standing/deep water for about 15 miles.
Setup is ZHP knob+ Z3 1.9 lever and all delrin bushings, so it SHOULD feel notchy, but it seems like I'm requiring a little bit more effort than usual.


I just did the trans fluid change, and I can't imagine water entering the trans through the bell housing, or any of the gaskets. And I'm positive my engine would have hydrolocked way before water could have reached the transmission breather valve.


Any ideas? I'm guessing these is one of those problems that will just ride itself out.

Your brake fluid is absorbing moisture and getting thicker,
so the clutch is having a harder time disengaging.

And it's absorbing cosmic rays, too.

You need another tinfoil hat.

Interesting conclusion - wouldn't have really thought about the brake fluid.

Now why would it be absorbing moisture? How does that happen?

Brake fluid is hygroscopic.


Delrin also absorbs water and swells. It's not a great choice for a tight clearance bushing exposed to water.


Don't forget your tin foil condom, too.
