Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, fluid catch pan, funnel.
• Remove the transmission dipstick (if equipped) and check fluid level.
• If low, add the recommended type of transmission fluid (consult the owner's manual).
• If the fluid is burnt or contaminated, proceed to replace it:
  • Place the fluid catch pan under the transmission pan.
  • Remove the transmission pan bolts using a socket set.
  • Carefully lower the pan and drain old fluid.
  • Replace the transmission filter if applicable.
  • Reattach the pan with bolts tightened to manufacturer's specifications.
  • Refill with new transmission fluid via the dipstick tube.

3. Inspect and Adjust Transmission Linkage

• Tools Required: Wrench set, socket set.
• Locate the transmission linkage on the driver’s side of the transmission.
• Check for any loose connections or damage.
• If misaligned, adjust the linkage according to the service manual specifications.
• Ensure the linkage moves freely without obstruction.

4. Test Solenoids and Electrical Connections

• Tools Required: Multimeter.
• Disconnect the electrical connector from the transmission solenoids.
• Use a multimeter to check for proper resistance values as specified in the service manual.
• Replace any faulty solenoids with new ones if necessary.
• Reconnect all electrical connectors securely.
