Here is information on the codes:
P0740: Torque Converter Clutch Circuit Malfunction.
P0753: Shift Solenoid A Electrical Malfunction.
P0785: Shift/Timing Solenoid Malfunction.
P1860: TCC PWM Solenoid Circuit Electrical Malfunction.
I would start by checking the electrical connector at the transmission. If that looks okay, I would install a rebuilt valve body. Check out the images (below). Please let us know what happens. Also, how is the fluid condition, is it burnt or low?
