Does X-TREEEMME Cold affect clutch operation?

The wind chill factor does not apply to vehicles. If it's 0 degrees outside with or without wind, the vehicle also is at 0 degrees.

If it's windy, a warm vehicle when parked outside will cool off faster than with no wind, but it will only cool off to 0 degrees, not lower.

like -29degC

Ya, I'm actually surprised they don't make a special winter xmission oil like they do for engines for us cold-climate folk. It was -28C here yesterday and my Corolla's clutch pedal was really stiff for the first 5 minutes or so. Just go easy on it. Also, windchill factor does not effect the vehicle.

Brake fluid (used in the clutch's hydraulic system) is not supposed to freeze, but given enough cold, everything will eventually freeze. Frozen clutch fluid would most certainly contribute to a stiff pedal.

Definitely ..... Clutch surfaces as well a brakes work by the dissipation of heat (friction) .... the colder it is the better for heat transferred and you get chatter and slip all at the same time (or the 'ability' of heat to be transferred drastically changes). The viscosity of lubrication thickens, tolerances of metal components close down .

..... and at the very coldest, essentially all molecular moti> Hey guys,

If you have mechanical linkage, when was the last time you greased it?

If not, then rubber parts/boots can get stiff and grease or pivot points on the pressure plate and throw out will be stiff.

The internal tranny oil has no bearing on that, only on shifting.

I went with a semi synthetic gear oil and notice the difference in cold shifting. My T5 can use a winter fluid though, it can use ATF in the winter and gear oil in the summer. Some run ATF all the time, but I won't.

Yep and the is known as Absolute Zero or 0 degrees Kelven..

I believe we call it "Canadian Prairie Winters" ...
