Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is on a level surface and secured with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

2. Transmission Fluid Change

Sub-steps:
1. Drain the Fluid:
  - Locate the transmission drain plug and place a drain pan underneath.
  - Remove the drain plug and allow the fluid to fully drain.
2. Replace the Filter:
  - Remove the transmission pan by loosening the bolts with a socket set.
  - Clean the pan and replace the filter according to the manufacturer's specifications.
3. Refill Transmission Fluid:
  - Reinstall the pan with new gasket material and torque bolts to manufacturer specifications.
  - Refill the transmission with the appropriate type and amount of fluid as specified in the owner’s manual.

3. Inspect and Replace Worn Components

Sub-steps:
1. Check Engine and Transmission Mounts:
  - Visually inspect mounts for cracks or excessive wear.
  - Replace any damaged mounts using a socket set and torque to specifications.
2. Inspect Throttle Position Sensor (TPS):
  - Disconnect the electrical connector and remove the TPS from the throttle body.
  - Test the TPS with a multimeter to ensure it operates within specifications. Replace if necessary.

4. Test Drive

After completing repairs, reconnect the battery.
Start the vehicle and check for any abnormal noises or warning lights.
Conduct a test drive to ensure the jerking issue has been resolved.
