904 Accumulator Spring

It really makes no difference rather its cold or hot, still no kick down. I've adjusted the bands with no luck. I'm going to change the line pressure next and see if that helps. Thanks guys.

I was thinking more about the shifting itself when I asked about cold and hot.

Find the measurement for the pressure regulator valve and see if it's somewhat close to stock first.
If it is, then do three full turns counterclockwise on the regulator valve adjuster bolt.

You will have to readjust your TP rod again after, but this should close up that flair and possibly give kickdown back.
