Solution

1. Preparation

Tools Required: OBD-II scanner, transmission fluid gauge, multimeter, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level; add fluid if low.
2. If the fluid is dark or has a burnt smell, drain the old fluid using a fluid pump.
3. Replace with the manufacturer-recommended transmission fluid (check the owner’s manual for specifications).
4. Refill the transmission through the dipstick tube to the proper level.
5. Start the engine and allow it to warm up; check fluid level again and add if necessary.

3. Test and Replace Transmission Solenoids (if faulty)

Sub-steps:
1. Remove the transmission pan and filter to access solenoids.
2. Use a multimeter to test the solenoid resistance; compare with manufacturer specifications.
3. Replace any faulty solenoids with new parts.
4. Reinstall the transmission pan with a new gasket and torque to specifications.

4. Reconnect and Road Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Perform a road test to ensure the jerking issue has been resolved.
3. Monitor for any error codes using the OBD-II scanner after the test drive.
