Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely elevated using jack stands.
Disconnect the battery before starting any work on electrical systems.

2. Change Transmission Fluid

Sub-steps:
1. Remove the transmission pan by loosening the bolts with a socket set.
2. Drain the old transmission fluid into a suitable container.
3. Clean the transmission pan and filter (if applicable) with appropriate cleaners.
4. Replace the transmission filter if necessary.
5. Reinstall the transmission pan with a new gasket, ensuring to torque the bolts to the manufacturer’s specifications (typically 8-12 Nm).

3. Inspect and Replace Components

Sub-steps:
