I know this is a longshot, and I haven't read all the posts about this
problem, but you might have some water in your transmission fluid, which
would explain the time it takes for the trans to work. Pull the dipstick
and see if your fluid looks like strawberry milk when it is warm. It is
possible the water in the fluid is freezing at night and not allowing
the fluid to flow through the proper circuits in the trans.
