Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check fluid level; add fluid if low (use ATF+4 fluid).
3. If fluid is dark or smells burnt, drain and replace the transmission fluid.
4. Remove the transmission pan (if needed) to access the filter and replace it.
5. Reattach the transmission pan and torque bolts to manufacturer specifications (usually around 10-12 ft-lbs).

3. Inspect and Replace Transmission Control Module (If Necessary)

Sub-steps:
1. Locate the transmission control module (usually near the transmission).
2. Disconnect the wiring harness from the module.
3. Remove the mounting screws and take out the old module.
4. Install the new module and reconnect the wiring harness.
5. Clear any stored error codes and perform a relearning procedure if required.

4. Check Engine Mounts

Sub-steps:
1. Visually inspect engine mounts for visible signs of wear or damage.
2. If damaged, remove the old engine mounts using a socket set.
3. Install new engine mounts and torque to manufacturer specifications.

5. Test Drive

Conduct a test drive to ensure the jerking issue has been resolved and that shifting feels smooth.
