Yeah. Is the AcDelco new or remanufactured? You will also need the spacer plates that go in between the valve body and channel plate. This will also reveal check balls, so you will need to know the locations they go in, and have some tranny goo to assemble them when it's on its side.

I'd like someone who knows transmissions more than me to stop by as well, I've never separated the valve body from the channel plate before, I just pulled the channel plate as an assembly.
