Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission dipstick (if applicable), funnel.
Remove the transmission dipstick (if equipped) and check the fluid level.
If low, add the recommended transmission fluid (consult owner's manual for specifications).
If burnt or contaminated, proceed to change the fluid.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, fluid pump, drain pan.
Locate the transmission pan and remove the bolts using the socket set.
Carefully lower the pan and drain the old fluid into a drain pan.
Remove the old transmission filter and replace it with a new one.
Clean the transmission pan and replace the gasket.
Reinstall the pan and tighten the bolts to the specified torque (consult manual for torque specifications).
Refill the transmission with the correct type and amount of fluid.

4. Inspect and Replace TCM or Sensors

Tools Required: OBD-II scanner, multimeter, basic hand tools.
If codes indicate a faulty TCM or sensor, remove the TCM from its mounting.
Disconnect the connectors and check for corrosion or damage.
Replace with a new TCM if necessary, following manufacturer instructions for programming.
For faulty sensors, disconnect and replace them with new components.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal securely.
Start the vehicle and allow it to idle for a few minutes.
Conduct a test drive to verify the jerking issue has been resolved.
