Cold Shifting
Just for your information, wind chill has no effect on your car. It has to do with the rate at which temperature transfer is done, such as the human warm skin being cooled by biting cold wind. Also, like blowing on your soup to cool it down faster.
Also, from my experience (one winter with a stock shifter, and this winter with the TWM short shifter), I found no difference at all in cold weather shifting. Both are kinda stiff when below -5C (23F). It get stiffer as the temperature drops. Has to do with the gear oil.
Within the next couple days, I will replace the stock tranny oil by Royal Purple synt oil. I was told that the synth gear oil will warm up faster.
I kind of beleive this, as since I switched my engine oil to Royal Purple Synth, the engine does warm up much faster in the winter.
