Band release

[larrym]

I have a question to help me with my 2-3 apply timing, its very close I have installed a CK plate and things are almost perfect. Under hard acceleration it shifts good but cruising and low speed shifts I can feel the band hanging on just a fraction of a second.
I want to re size the band release orifice and just need some input on how much bigger to make the opening and confirm which one I'm going to re size.

#5 3rd accumulator?

Is the direct clutch dual fed?

 

[larrym]

no its not dual fed.

Any one?
do I open up #5 3rd ACC to encourage the band to release sooner?
