Back into hydraulics a little bit... Allison Automatic valve body and Ford IPR valve

What I've got from digging into these is that they are really not very complicated. All that makes that Allison (3060 I believe?) work are 6 solenoids and 4 ports. Clutch packs etc are the same as any other automatic and are somewhat familiar as I've been in a Ford AOD before.
