Have to disengage the OD button and drive around without OD

Overdrive feels like neutral, have to disengage the OD button and drive around with out OD. Read a bunch saying OD snap ring, watch a lot of videos saying snap ring, like 95% of people are saying the snap ring. Okay.
I bought all my parts, dropped the pan, removed the valve body was ready for broken pieces and nothing. Pretty clean for having just over 200,000 fluids never low.

Clean the valve body made sure all the valves moved nice and weren't stuck or jammed, everything looked really good. In my opinion there was no reason to remove the overdrive servo and snap ring.
Put ever thing back together and still have neutral when OD kicks in.

Watch more videos and looked up more forums and so on. I am thinking well maybe the head of the servo is broken, I do not know. Maybe it became disconnected from the OD band? So.I dropped the pan again removed the valve body once again, removed the gasket the best I could but still some places broke so had to get a new gasket no biggie I am thinking. Looked up inside and from what I have been researching the OD band was in place. I do not know, but I still got my new snap ring pliers had to make a jack work to push the servo up so I could remove the snap ring bota bing bato boom started lowering the valve body and I could here the band slip back. I am like well that's weird sounded like the band was connected to the servo.

Put every thing back, . Fun. Really wasn't that bad. Even that new gaskets, check balls. Check balls seams intimidating but wasn't that hard. They have there special little homes that kinda stick out plus I marked them and took pictures. Filled the transmission up but still the same problem but now the OD light is flashing and transmission fault is on the dash? Also hard shift from 1-2.
I am looking for places now to see if they have a transmission scanner. No check engine light though so I hope for something good.
Thanks, Henry
