Honda Accord 9th Generation (2013-2017) CVT overheating warning, what should I do?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal for safety.

2. Check and Replace CVT Fluid

• Tools Required: Socket set, transmission funnel, fluid catch pan.
• Remove the CVT fluid drain plug and allow old fluid to drain into the catch pan.
• Inspect the drain plug for metal shavings; this may indicate internal wear.
• Reinstall the drain plug and torque it to the manufacturer’s specifications (usually around 30 ft-lbs).
• Using a transmission funnel, add the recommended CVT fluid (typically Honda HCF-2 or equivalent) through the dipstick tube.
• Start the engine, cycle through gears, and check fluid level, adding more fluid as necessary.

3. Inspect and Clean Transmission Cooler

• Tools Required: Wrenches, cooling system flush kit.
• Locate the transmission cooler lines connected to the radiator.
• Disconnect the lines and inspect for blockages.
• Use a cooling system flush kit to backflush the cooler, ensuring all debris is cleared.
• Reconnect the cooler lines securely.

4. Address Fluid Leaks

• Tools Required: Mechanic's gloves, sealant (if applicable).
• Inspect all transmission seals and gaskets for leaks.
• Replace any damaged seals and apply sealant as needed to ensure a proper seal.
• Recheck fluid levels after repairs.
