There is a huge difference between conventional and synthetic oils at cold temperatures. The viscosity ratings are at operating temperature (about 212°F) and regardless of synthetic or conventional, the same grade oil will have the same viscosity. However, as temperatures decrease, conventional oils will get much thicker than synthetics, even if they are the same grade.

If you can convert to synthetic, I'm sure you will notice a big improvement in cold weather.

The ford trans fluid is full synthetic and I run 0w-20 in the winter. 5w-20 in the summer for cost ($25 for 5 quarts vs $18 for 5 quarts).

The problem is I can shift. If I shift out of 1st at 1500RPM, in second it's going to be 1000RPM. As soon as I press in the clutch, the engine races up to 2000 and it just won't shift when it's that cold.
