Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Change Transmission Fluid

Fluid Inspection:
- Remove the transmission dipstick and check fluid level; add fluid if low.
- Examine fluid for contamination (burnt smell or dark color).
Fluid Change:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully drain the old fluid.
- Clean the transmission pan and replace the filter if applicable.
- Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (usually around 10-15 ft-lbs).
- Fill with new transmission fluid (consult owner’s manual for the correct type and quantity).

3. Inspect Transmission Mounts

Check the transmission mounts for wear or damage.
If damaged, remove the old mounts and replace them with new ones, ensuring proper alignment.

4. Reprogram Transmission Control Module (if applicable)

Using an OBD-II scanner, access the transmission control module settings.
Follow the manufacturer’s instructions to reset or reprogram the module.
Test drive the vehicle to ensure the changes have resolved the jerking issue.
