Nocturnall

my trans is starting to act really weird. Shifting into 3rd today it seemed as if it got confused. It shifted out of second and then nothing for about 7 seconds, then it remembered what was going on and shifted into 3rd. Also going from a stop taking a left turn kind of on it the car like...pauses, it's hard to explain, almost like if a manual I throw the clutch in for a second, maitain rpms and then let it back out and off I go. These possible signs of the tranny dying or could it be that it was just cold. Fluid was changed not even 6k miles ago, and all I have done to it is a vette servo.
