Dresser 530 1987 transmission schematic

Looking for a Little help on the transmission's Electrical Schematic for a Dresser 530 from 1987, seems like a Mc Gyver was trying to fix a solenoid problem and had change/suspend sensors and wires. I would love to have the machine on its original electrical state to start troubleshooting for mechanical if any. As for now 530 is not moving at all neither forward either reverse. Thanks in advance for any info.
