Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid, fluid catch pan.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Replace Transmission Fluid

Sub-steps:
1. Place a fluid catch pan under the transmission pan.
2. Remove the transmission pan bolts using a socket set and carefully lower the pan to drain the old fluid.
3. Remove the old transmission filter and replace it with a new one.
4. Clean the transmission pan and replace the gasket.
5. Reattach the transmission pan, torque bolts to manufacturer specifications (typically 8-10 ft-lbs).
6. Refill the transmission with the appropriate fluid type according to the owner’s manual.

3. Inspect and Replace Damaged Components

Sub-steps:
1. Inspect transmission mounts for cracks or excessive wear. Replace if necessary.
2. Check engine mounts and replace if they show signs of damage.
3. If the throttle position sensor is faulty, disconnect the electrical connector and remove the sensor. Install the new sensor and reconnect the wiring.

4. Test Drive

Conduct a test drive to ensure proper shifting and to verify that the jerking issue is resolved.
