Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (for automatic) or drain plug (for manual) under the vehicle.
2. Remove the dipstick or drain plug; check the fluid condition. If it's dark or has a burnt smell, it needs to be replaced.
3. If necessary, drain the old fluid completely into a suitable container.
4. Replace with the recommended transmission fluid (consult owner’s manual for specifications).
5. Reinsert the dipstick or replace the drain plug securely.

3. Inspect and Repair Transmission Control Module (TCM)

Sub-steps:
1. Locate the TCM, typically found near the transmission or under the dashboard.
2. Disconnect the TCM connectors carefully.
3. Inspect the connectors for corrosion or damage; clean or replace as necessary.
4. Reconnect the TCM and ensure all connections are secure.

4. Test and Replace Transmission Solenoids

Sub-steps:
1. Access the transmission solenoids by removing the transmission pan (if necessary).
2. Use a multimeter to test the resistance of each solenoid; compare readings with specifications from the service manual.
3. If any solenoid is outside the specifications, replace it with a new one.
4. Reinstall the transmission pan with a new gasket and torque to manufacturer specifications.
