If it is whining with load, it sounds like the pump is starting to go out on it. Also, it will have more issues with cold fluid since it will be a thicker consistency and even harder to pump, so harder to get the fluid where it needs to go to apply the proper parts in the transmission.
I have a buddy's car that is getting a 5 spd done and when its below 25 degrees, it's so bad that it has to spin up to 3500 rpm when first put in gear in order for it to actually start moving. In the warmer weather, there aren't any issues at all other than the whining.
