tranny question

[92grandprixx]

I have a 92 grand prix with a 3.1 and in the morning the tranny will not shift into its final gear or lock up till the temp is between the 100* mark and the first line everytime ..once its there or warmer it will shift into its final gear and then into lockup...I have changed the fluid and filter,but still the samething.other than that tranny shifts great!...any ideas?
thanks
