When you change your transmission fluid, did you also change filter for it?
I wonder wheter changing filter need more quarts of fluid.
And, if I just change fluid not filter, is it a bad idea?
Have a good day.
Yes that was with dropping the pan and changing the filter. (betweeen 5-6qts used)

Just changing the fluid would be a half measure. Why bother then? Would you want to change your engine oil without changing the oil filter? Probably not. Spend the extra 20-30 minutes and drop the pan, clean it, and swap the filter for a new one. Then in 5-10 thousand miles if you want do a drain/refil to get more of the old fluid out of there.
