Solution

1. Preparation

Gather tools and parts: Ensure you have an OBD-II scanner, socket set, torque wrench, transmission fluid pump, and new CVT fluid.
Safety precautions: Disconnect the battery to prevent electrical shorts and allow the engine to cool before starting work.

2. Fluid Change

Drain old CVT fluid:
1. Position a drain pan under the transmission pan.
2. Remove the drain plug and allow fluid to fully drain.
Replace CVT fluid:
1. Remove the transmission pan if necessary.
2. Replace the transmission filter.
3. Reinstall the pan with a new gasket and torque to manufacturer specifications (typically around 8-10 ft-lbs).
4. Refill the CVT with new Honda-approved CVT fluid using a fluid pump.

3. Inspect and Replace Components

Inspect CVT belt and pulleys:
1. Remove the transmission case cover.
2. Check the CVT belt for wear and replace if cracked or frayed.
3. Inspect the pulleys for scoring or damage and replace as necessary.
4. Reassemble the cover with proper torque specifications.

4. Reset Transmission Control Module (TCM)

Reset the TCM:
1. Reconnect the battery.
2. Use the OBD-II scanner to reset error codes and clear TCM adaptations.
