There is a tool for checking end play before the pump ever goes in, but only shops have them unless someone is into it more than most.
You set it up like you see in the pic and then flip it over so it shows the distance between the pump surface on the case to the front drum washer surface.
When you open ADHD Transmissions you might pick one up. :D
Greasing the pump gears heavily insures the pump gears seal really well on startup to get fluid moving right away. (not a huge deal)
DON'T forget to air check that thing before you put a valve body on it.
Servo's should snap out and back in with not very much extra air noise.
Clutchpacks should make a clunk type sound when they apply and you will hear a little air escaping down inside the trans. (this is just air getting around sealing rings and such, and is normal.)
Fluid is much thicker and won't get past things near as easy.
Of course that isn't a Chrysler pump, but the tool works the same way with other transmissions.
