Solution

1. Preparation

• Gather tools and create a clean working environment.
• Disconnect the battery to prevent electrical shorts.
• Tools required: OBD-II scanner, multimeter, socket set.

2. Fluid Inspection and Replacement

• Inspect Transmission Fluid:
  • Remove the transmission dipstick.
  • Check fluid level and condition; it should be pink and not smell burnt.
• Replace Fluid if Necessary:
  • If fluid is low or contaminated, drain the transmission fluid using a socket set, and replace it with the manufacturer-recommended fluid.
  • Torque the drain plug to the manufacturer's specification.

3. Solenoid Replacement (if faulty)

• Remove Transmission Pan:
  • Remove the bolts securing the transmission pan using a socket set.
  • Carefully lower the pan to avoid damaging the gasket.
• Replace Solenoids:
  • Locate and remove the faulty solenoids from their positions.
  • Install new solenoids, ensuring they are seated correctly.
  • Reinstall the transmission pan, using a new gasket if necessary, and torque the bolts to specifications.

4. Reconnect and Test

• Reconnect the battery.
• Clear the P0700 code using the OBD-II scanner.
• Test drive the vehicle to verify that the issue is resolved and that the check engine light does not reappear.
