Solution

1. Preparation

• Gather tools and parts required: OBD-II scanner, multimeter, socket set, torque wrench, replacement transmission fluid, and possibly a new transmission control module or range sensor.
• Ensure the vehicle is on a level surface, and the engine is off and cool.

2. Addressing Fluid Issues

• Check Fluid Level:
  • Remove the transmission dipstick.
  • Wipe clean, reinsert, and remove again to check fluid level.
• Change Transmission Fluid:
  • Place a drain pan under the transmission pan.
  • Remove the transmission pan bolts using the socket set and carefully lower the pan.
  • Drain old fluid and replace the filter if applicable, then reassemble with new fluid.

3. Repairing Electrical Issues

• Inspect Wiring and Connectors:
  • Disconnect the battery to ensure safety.
  • Visually inspect wiring harnesses connected to the TCM and transmission for damage.
  • Repair or replace any damaged wiring or connectors.
• Test and Replace Components:
  • Test the transmission control module with a multimeter; if faulty, replace it according to manufacturer specifications.
  • If the transmission range sensor is faulty, remove it and replace with a new unit, ensuring proper alignment.

4. Reassemble and Reset

• Reinstall the transmission pan with new gasket if necessary, and torque bolts to manufacturer specifications.
• Reconnect the battery.
• Use the OBD-II scanner to clear the P0700 code and any other related codes.
