Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if applicable) and remove it.
2. Use a funnel to extract the transmission fluid; if it appears dark or has a burnt odor, it needs replacing.
3. Refill with the manufacturer-recommended transmission fluid (e.g., Ford Mercon LV) through the dipstick tube.
4. Start the engine and let it run to circulate the fluid; recheck the level and top off as necessary.

3. Inspect and Replace Transmission Mounts

Tools Required: Socket set, jack stands, floor jack
Sub-steps:
1. Safely lift the vehicle using a floor jack and secure it with jack stands.
2. Locate the transmission mounts; visually inspect for cracks or excessive wear.
3. If damaged, remove the bolts securing the mounts using a socket set.
4. Replace with new mounts, ensuring they are aligned properly and torque bolts to the manufacturer's specifications.

4. Throttle Position Sensor (TPS) Testing and Replacement

Tools Required: Multimeter, screwdriver set
Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the electrical connector and use a multimeter to check the voltage while slowly opening the throttle.
3. If voltage does not vary smoothly between 0.5V and 4.5V, replace the TPS.
4. Install a new TPS and reconnect the electrical connector.

5. Reconnect Battery and Road Test

Reconnect the battery terminals.
Start the engine and allow it to idle for a few minutes.
Perform a road test to confirm that the jerking issue has been resolved.
