Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fluid catch pan
Park the vehicle on a flat surface and engage the parking brake.
Allow the engine to cool down if it has been running.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if applicable) and remove it.
2. Check the fluid level; if low, add the appropriate type of transmission fluid (usually Toyota WS).
3. If the fluid is dirty or burnt, drain the transmission fluid using a fluid catch pan.
4. Replace the transmission filter (if equipped) and install a new gasket as needed.
5. Refill the transmission with new fluid to the recommended level.

3. Inspect Transmission Linkage

Sub-steps:
1. Remove any covers or panels obstructing access to the transmission linkage.
2. Visually inspect the linkage for any signs of wear or damage.
3. Adjust the linkage as necessary to ensure proper alignment and operation.
4. Secure all fasteners and replace any damaged components.

4. Test and Replace Transmission Solenoids (if necessary)

Sub-steps:
1. Disconnect the battery to prevent electrical short circuits.
2. Remove the solenoid assembly from the transmission.
3. Use a multimeter to test each solenoid for resistance; replace any that are out of specification.
4. Install new solenoids and reconnect the wiring harness.

5. Reassemble and Test Drive

Sub-steps:
1. Reattach any covers or panels removed during the repair.
2. Reconnect the battery.
3. Start the engine and conduct a test drive to ensure that the jerking issue has been resolved.
