Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Transmission Fluid Change

Sub-steps:
1. Locate the transmission pan and remove the bolts using a socket set.
2. Carefully lower the pan to drain old fluid into a suitable container.
3. Check the transmission filter; replace if clogged or damaged.
4. Install a new gasket on the transmission pan.
5. Reattach the pan and tighten bolts to manufacturer specifications.
Tools Required: Socket set, fluid container, new transmission filter, new gasket.

3. Inspect and Test Solenoids

Sub-steps:
1. Locate the transmission solenoids, usually found on the valve body.
2. Disconnect electrical connectors from solenoids.
3. Use a multimeter to check resistance values against manufacturer specifications.
4. Replace any faulty solenoids with new components.
Tools Required: Multimeter, socket set for solenoid removal.

4. Reprogram Transmission Control Module (if necessary)
