Yes, you drill out a few existing passages and block one. To block the passage, you camphere the hole so instead of:

you have:
\ /

you do this with a drill bit and not drilling through the entire plate. I believe this is done to the top VB plate. I will quote the directions tonight when I get home.
Once camphered, you rivet the hole with a small rivet provided and then file both sides flat. What you are left with is a blocked passage. This is the only step of the install that has me hesitant of doing it myself. I am going to talk to a tranny shop today and see what they would charge to install this, the in-line filter and auxillary cooler I plan on buying shortly.
I will keep you updated!
