Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted if required.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the dipstick and check fluid levels.
If low, add the recommended transmission fluid as per Honda specifications.
If the fluid is burnt or contaminated, proceed to drain and replace the fluid.

3. Inspect and Replace Sensors

Transmission Fluid Temperature Sensor:
- Locate the sensor on the transmission.
- Disconnect the electrical connector.
- Remove the sensor using a socket wrench.
- Install the new sensor and reconnect the connector.
Input and Output Speed Sensors:
- Locate each sensor on the transmission.
- Disconnect the connectors and remove the sensors.
- Clean the sensor mounting areas.
- Install new sensors and reconnect the wiring.

4. Reassemble and Refill

If the transmission fluid was drained, refill with the correct type and amount of fluid.
Reconnect the battery.

5. Reset and Test

Use the OBD-II scanner to clear the trouble codes.
Start the engine and let it warm up, then conduct a test drive to ensure normal operation.
