Downshift Switch

  1. Inspect wiring and components for shorts, corrosion, overheating, loose connections, or any other damage. Check 10-amp METER fuse. Disconnect downshift solenoid.
  2. With key off, voltage measured at Black/Blue  wire should be zero volts. With key on and accelerator pedal fully depressed, voltage should be greater than 10 volts. If Black/Blue  wire is okay, remove downshift solenoid.
  3. Apply battery voltage to downshift solenoid connector and ground case. Control rod should move freely when solenoid case is grounded. If control rod does not move freely, replace downshift solenoid.
