Hi I'm Wayne

I will help you with this

what you are describing is the front servo housing Pump

in the trans is failing , you can test all day , trans needs to be torn down

I have seen this before on a truck , we spent many hours

trying to find the issue , sent it to a Friend of mine Trans Shop

BTW, went to him 1st , he said no issue,

after 2nd day , We pulled trans and asked him to tear it down

and sure enough he found a crack in the pump housing

I hope this help you
