Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Change Transmission Fluid

Sub-steps:
1. Remove the transmission pan by loosening the bolts with a socket set.
2. Allow the old fluid to drain completely into a catch pan.
3. Inspect the transmission filter and replace it if necessary.
4. Clean the transmission pan, ensuring no debris remains.
5. Reinstall the pan with a new gasket and torque the bolts to the manufacturer's specifications (refer to the service manual for exact torque values).
6. Refill the transmission with new fluid as specified in the owner's manual (check for the correct type of fluid).

3. Inspect and Replace Transmission Solenoids (if necessary)

Sub-steps:
1. Identify the location of the transmission solenoids based on the vehicle’s service manual.
2. Disconnect the electrical connectors and remove the solenoids from their mounting positions.
3. Compare the old solenoids with new ones to ensure correct replacement.
4. Install new solenoids and reconnect the electrical connectors.

4. Reset Transmission Control Module (TCM)

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to reset any transmission fault codes.
3. Perform a relearn procedure for the TCM if required by the vehicle's service manual.
