As the weather has turned cooler, I notice that the Transmission is slow to shift out of first, and maybe second gear for the first minute of driving or so. It does not feel like it is slipping - just holds off shifting till rpms go up and maybe I let off the gas. It acted this way on a couple of ocasions last winter, but only when the weather was below zero. Now it is acting up in moderate weather (40 degrees F).

Over the years I have followed with keen interest the debate regarding flush/no flush philosophies. I don't know the right answer, but have decided to change the fluid to see if it will fix the slow shift problem. I checked bay13 and searched the archives and have seen conflicting answers to this simple question:

When flusning the transmission by disconnecting the top hose into the cooler, does the fluid pump out of the top hose, or out of the top fitting on the radiator?

The car has 160K and this will be the first flush. What non-synthetic fluid is recommended? May upgrade to synthetic at a later date.

TIA
