Stiff clutch when cold
This winter here in Ohio has been colder than normal. I have noticed when the temperature drops below 0F, the clutch is much more difficult to disengage. And when engaging it (letting off the pedal) it is a bit sluggish. When driving around town, the issue seems to go away. But when driving on the highway, the clutch stiffens up again.
My guess is the fluid that operates the clutch cylinder becomes more viscous when cold. Or is there another cause? Any solution? A different kind of fluid maybe???? It is not a big deal, just a bit annoying. |

I don't think there is a solution for this. It happened to mine since new.. the clutch cylinder uses the brake fluid, i don't think you can do anything about it.

it is because the brake fluid thats used in the system becomes more viscous like you said. It gets better while driving at slow speeds around town because it is getting warmed up by the engine and warm air from the rad. At Highway speed it cools off and becomes stiff again. flushing the system with fresh fluid might help or maybe use a compatable synthetic brake fluid. my yaris and my pickup do the same thing.

Not brake fluid, tranny fluid is cold. Happens to most cars. A switch to a good synthetic fluid can help. I like redline or amsoil
