Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Fluid Change

Tools Required: Transmission fluid pump, socket set, drain pan, funnel
Remove the transmission pan using the socket set to access the fluid.
Drain the old transmission fluid completely into the drain pan.
Replace the transmission filter if applicable. Ensure the new filter matches OEM specifications.
Reinstall the transmission pan with a new gasket or sealant if required. Torque the bolts to the manufacturer's specifications (typically around 8-10 ft-lbs).
Fill the transmission with new, manufacturer-recommended transmission fluid using the funnel and fluid pump. Check the fluid level with the dipstick as per the owner's manual.

3. TCM Reset

Tools Required: OBD-II scanner
Reconnect the battery terminal.
Use the OBD-II scanner to clear any stored fault codes related to the transmission.
Perform a TCM reset if the scanner provides this option.

4. Test Drive

Conduct a test drive to ensure the jerking issue has been resolved. Monitor the transmission performance through various driving conditions.
