2004 Grand Prix, trans shifting issues

when cold the trans has "firmer/harder" shifts 1-2 is the worst, the others are ok. However when it's hot the shifting is very good, super smooth, you need to watch the tach to tell when it shifts. it shifts harder into reverse/drive, randomly hot/cold but only for the first few times of the day. (not a clunk, but it will get like that if no i don't do something now.)

I am however noticing that there is a delay between shifts, not a long time but it's there. I am thinking of a doing a pan drop and filter, with SYN ATF. Dex 4 right or better? is there anything else I could check or do?

Thanks.
