Do I need to replace the channel gaskets out of the valve body for an automatic transmission?

I'm rebuilding my transmission and it's a CD4E out of a 2001 mazda 626. I took the valve body apart to install a shift kit (Looks like it already has one). I think it's called the channel gaskets or the accumulator gaskets but it's the gaskets that go inside the valve body when taking it apart, They look good but do I need to replace them anyways?
are they not in the over haul kit
