Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine turned off.
• Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Transmission Fluid

• Sub-steps:
  1. Raise the vehicle using a jack and secure with jack stands.
  2. Place a drain pan under the transmission pan to catch old fluid.
  3. Remove the transmission pan bolts using a socket set and carefully remove the pan.
  4. Drain the old transmission fluid completely and inspect the pan for metal shavings or debris.
  5. Replace the transmission filter if it is clogged or damaged.

3. Test Transmission Solenoids

• Sub-steps:
  1. Disconnect the wiring harness from the solenoids located on the transmission.
  2. Use a multimeter to test the resistance of each solenoid; compare readings to manufacturer specifications (usually around 20-30 ohms).
  3. Replace any solenoids that are out of specification.

4. Reconnect Battery and Test Drive

• Sub-steps:
  1. Reconnect the battery terminals.
  2. Start the engine and allow it to warm up.
