What steps do I need to make? 46RE

Notice that taking too long to make that first shift, then after it's mostly normal, reverse is good.
Would it do me any good to take out all solenoids and clean them along with fresh fluid?
Definitely NOT a transmission guy here, but I can be trained....

Any and all advice listened too, feel free to talk slow and spell out the big words like cat, dog, and fluid.....lol

This has really been the problem I can't live with. (Finally got the blend door motor, and it'll be replaced soon.)

Thanks in advance, I'll be checking back in as time allows...

What year is your truck and how many miles on it? does it only happen when trucks cold? Like when it warms up does it shift normal? Its normal for shifts to be long/sluggish until the truck warms up a bit.
