Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative terminal of the battery for safety.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
Remove the transmission fluid drain plug and allow the fluid to completely drain into a suitable container.
Inspect the old fluid for signs of burning or contamination.
Replace the drain plug and torque it to the manufacturer's specifications (typically around 30 lb-ft).
Refill the transmission with the correct type and amount of fluid (Honda ATF CVT fluid), using a fluid pump and funnel.

3. Inspect and Clean Transmission Cooler

Tools Required: Wrench set, cleaning solvent, brush.
Disconnect the transmission cooler lines from the transmission.
Inspect the cooler for debris or blockages; clean with a solvent and brush if necessary.
Reconnect the cooler lines, ensuring they are secure and leak-free.

4. Check Radiator and Cooling System

Tools Required: Cooling system pressure tester, hose clamps.
Inspect the radiator for leaks and ensure the coolant level is adequate.
Use a cooling system pressure tester to check for pressure loss; repair any leaks found.
Flush the cooling system if necessary and refill it with the recommended coolant.

5. Replace Transmission Temperature Sensor (if faulty)

Tools Required: Socket set, torque wrench.
Locate the transmission temperature sensor and disconnect the electrical connector.
Remove the sensor using a socket and replace it with a new one.
Torque the new sensor to the manufacturer's specifications and reconnect the electrical connector.
