John Deere 000736.06 – PTQ: Gear Selector Clutch K1 Solenoid Amps High

The Gear Selector Clutch K1 Solenoid is drawing excessive electrical current, as detected by the PTQ (Main Control Module). This condition typically indicates an electrical fault, such as a short circuit to ground in the solenoid's wiring harness, oil contamination in the connector, or an internal failure of the solenoid coil itself.

1. 1

   Visually inspect the wiring harness leading to the transmission control solenoids for chafing, melting, or corrosion on the connectors.

2. 2

   Check the wiring harness for a short to ground, particularly where it might rub against the chassis. Pay special attention to the common power wire for the solenoids.

3. 3

   Unplug the K1 solenoid connector and check for hydraulic oil seeping through the pins, which can cause a short.

4. 4

   Test the resistance of the solenoid coil using a multimeter. A reading of zero or very low resistance indicates an internal short circuit.

1. 1

   Disconnect battery

   Disconnect the battery before beginning any electrical repair work for safety.

2. 2

   Locate the solenoid

   Locate the speed control solenoids (including K1) on the side of the transmission housing. Remove the protective skid plate if necessary for access.

3. 3

   Drain transmission fluid

   If necessary based on the solenoid's location, drain the transmission fluid into a suitable container to avoid spills during removal.

4. 4

   Remove the old solenoid

   Disconnect the electrical connector. Using the appropriate wrench, carefully unscrew and remove the solenoid from the transmission valve body.

5. 5

   Install the new solenoid

   Thread the new solenoid in correctly and tighten to the proper torque specification. Ensure any new O-rings or seals provided with the replacement part are used.

6. 6

   Reconnect and refill

   Reconnect the electrical connector. If fluid was drained, refill the transmission with the correct John Deere-approved hydraulic/transmission fluid.

7. 7

   Clear fault codes

   Reconnect the battery and clear the fault codes from the control module using the tractor's diagnostic system.

8. 8

   Perform transmission calibration

   Initiate a transmission calibration through the tractor's CommandCenter display. Warm the transmission oil to the specified temperature and follow the on-screen prompts to allow the control unit to learn the new solenoid's electrical characteristics.
