If you haven't had much experience repairing automatic transmissions, it might be best to work with a qualified mechanic to replace the valve body on your Saturn.

throttle body
If the transmission is slipping or shifting badly it COULD be a sign of a valve body failure. If the transmission will not engage reverse or any of the forward gears, it COULD be a sign of a valve body failure.
in the transmission valve body
install shift kit by removing trans or drop pan and install upgraded solnoids in valve body
Remove the pan from the transmission. You will have to drop the valve body. The solenoids are on top of the valve body. Unplug it and screw it out. Be careful the gaskets for the valve body are very brittle and will break easily.
I am prettysure you can change the motor as long as the body structure is the same and you have skill in this sort of thing.
if you have the valve body and you kno what your doin you drop the pan, remove the valve body bolts drop it straight down then install the new, but id recommend taking it to a tranny shop to have them replace it for you.
