One of the most common complaints we hear about using aftermarket gear oils instead of the OEM stuff is incredibly stiff shifting when cold. As it has been unusually cold this early in your area, this could be your issue.

Gear oil (Redline 75W90) has 29,000mls and 2 years on it. With regard to temps, I considered the same thing. What's weird is that it shifted fine on initial start. Granted I only had a mile and half to drive, but it went through reverse, 1st, 2nd and 3rd just fine. 25 minutes later it's like filled it with cement...
