Safety Warnings: Disconnect the battery before starting work on electrical systems. Allow the engine and transmission to cool before inspecting.

2. Change Transmission Fluid

1.1: Lift the vehicle securely using jack stands.
1.2: Place a drain pan underneath the transmission pan.
1.3: Remove the drain plug or pan bolts (if applicable) and allow the fluid to fully drain.
1.4: Replace the drain plug, ensuring it is torqued to manufacturer specifications.
1.5: Fill the transmission with new CVT fluid through the dipstick or fill port using a fluid pump until it reaches the proper level.

3. Replace Input/Output Speed Sensor

2.1: Locate the input and output speed sensors on the transmission.
2.2: Disconnect the electrical connectors from both sensors.
2.3: Remove the mounting bolts using a socket set and carefully pull out the sensors.
2.4: Install the new sensors and torque the bolts to specifications.
2.5: Reconnect the electrical connectors.

4. Inspect and Replace CVT Belt (if necessary)

3.1: Remove any necessary components to access the CVT belt (consult repair manual for specific instructions).
