Solution

1. Preparation

Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Change Transmission Fluid and Filter

Drain the Transmission Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully tilt the pan to drain the fluid.
- Discard the old fluid properly.
Remove and Replace the Transmission Filter:
- Remove the old filter from the transmission.
- Install the new filter, ensuring it is seated correctly.
Clean the Transmission Pan:
- Scrape off old gasket material from the pan.
- Clean the pan thoroughly with solvent and allow it to dry.
Reinstall Transmission Pan:
- Apply a new gasket or RTV sealant as per manufacturer specifications.
- Reattach the transmission pan and torque the bolts to the manufacturer's specifications (typically around 8-12 lb-ft).
Fill Transmission with New Fluid:
- Use the appropriate type of transmission fluid specified for the Honda Pilot (usually Honda ATF-Z1 or DW-1).
- Fill the transmission through the dipstick tube using a funnel.

3. Test Drive

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature.
Check for leaks and perform a test drive to ensure the slipping has been resolved.
