Massey Ferguson T111 – TRANS1: Forward Clutch Solenoid Low Amps

The transmission controller is detecting an abnormally low electrical current (less than 13 milliamps) on the circuit that operates the forward clutch solenoid. This condition typically indicates an open circuit, a broken wire, a disconnected plug, severe corrosion causing high resistance, or a completely failed (open) solenoid coil.

1. 1

   Visually inspect the wiring harness leading to the Forward Clutch Solenoid (TR23, TR25, or X556) for broken wires, chafing, or unplugged connectors

2. 2

   Disconnect the plug at the forward clutch solenoid and check for water ingress, dirt, or corroded pins. Clean with contact cleaner if necessary

3. 3

   Measure the resistance across the two pins of the forward clutch solenoid coil using a multimeter. Compare to the reverse clutch solenoid; infinite resistance (OL) indicates a broken internal coil

4. 4

   If the solenoid tests good, check the continuity of the wiring harness from the solenoid connector back to the Autotronic 5 (TRANS1) controller pins to rule out a broken wire in the loom

1. 1

   Park and secure tractor

   Park the tractor on a level surface, turn off the engine, remove the key, and engage the parking brake.

2. 2

   Clean valve block area

   Clean the area around the transmission control valve block to prevent dirt from entering the hydraulic system.

3. 3

   Disconnect electrical connector

   Disconnect the electrical connector from the faulty forward clutch solenoid.

4. 4

   Remove retaining nut

   Remove the retaining nut or screw at the end of the solenoid stem.

5. 5

   Remove old solenoid coil

   Slide the old solenoid coil off the valve cartridge. (Note: On many models, you can replace just the electrical coil without removing the hydraulic valve cartridge, which prevents fluid loss).

6. 6

   Install new solenoid coil

   Slide the new solenoid coil onto the valve stem and secure it with the retaining nut.

7. 7

   Reconnect electrical connector

   Reconnect the electrical connector.

8. 8

   Clear fault code

   Turn the ignition on and clear the T111 fault code from the Autotronic controller using the tractor's diagnostic menu or a diagnostic tool.

9. 9

   Perform calibration

   Perform a clutch pedal/shuttle calibration after replacing transmission solenoids to ensure smooth engagement and prevent harsh shifting.

10. 10

    Test drive tractor

    Test drive the tractor to confirm the forward gear engages properly and the code does not return.
