Transmission book 850 93

Can anyone tell me where to get a book on the 850 automatic trans, particularly one that include the wiring diagrams. My trans skips second gear and the error code indicates the S1 solinoid. I don't even know where the S1 solenoid is, if it's internal or external. I am also suspicious about the wiring and connectors. I originally had error codes for S1 and S2 but when I disconnected and reconnected the main plug on the trans, the S2 error went away.
