Solution

1. Preparation

Tools Needed: OBD-II scanner, socket set, transmission fluid dipstick, funnel, and clean rags.
Ensure the vehicle is on a flat surface and the engine is turned off.
Disconnect the battery for safety.

2. Check and Replace Transmission Fluid

Locate the Transmission Dipstick:
- Open the hood and locate the transmission dipstick (if applicable).
Check Fluid Level:
- Remove the dipstick, wipe it clean, reinsert it, and check the fluid level.
Inspect Fluid Condition:
- If the fluid is dark or smells burnt, it needs to be replaced.
Replace Fluid:
- If necessary, remove the transmission drain plug (if equipped) and drain the old fluid into a container.
- Reinstall the plug, then using a funnel, add new transmission fluid as specified in the owner's manual (usually Toyota ATF WS).
Check for Leaks:
- After replacing, start the engine and shift through all gears, then check for leaks around the transmission.

3. Inspect Transmission Control Module (TCM)

Access TCM:
- Identify the location of the TCM (usually near the transmission or under the dashboard).
Inspect Connectors:
- Check all wiring and connectors for corrosion or damage.
Re-seat Connections:
- If connections appear loose, disconnect and reconnect them securely.

4. Test Drive

After completing the above steps, take the vehicle for a test drive to ensure the jerking issue has been resolved.
