tranny running cooler

[gtnit]

I judt did the tranny fluid change and the tp filter in the front. I have noticed the tranny runs much cooler on myh dash gauge and it takes alot longer to to come all the way up to temp. Before it would be up to temp and higher then what is normal now in just a few minutes not it may take 10 min. Any one else experiance this? I assume the cooler temps are good.
