how to diagnose a transmission slipping issue in my Honda Accord 10th Generation (2018-2022)

Solution

1. Preparation

• Gather Tools: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, cleaning rags.
• Safety Precautions: Ensure the vehicle is on a flat surface and engage the parking brake.

2. Change Transmission Fluid

• Drain Old Fluid:
  • Remove the transmission drain plug using a socket wrench.
  • Allow the old fluid to fully drain into a container.
• Replace Filter (if applicable):
  • Remove the transmission pan by unscrewing the bolts (use a torque wrench for reinstallation).
  • Replace the transmission filter, ensuring the new filter is properly seated.
• Install Pan and Torque:
  • Clean the transmission pan and apply a new gasket or sealant as necessary.
  • Reinstall the pan and torque the bolts to manufacturer specifications (typically 8-12 ft-lbs).

3. Refill Transmission Fluid

• Refill:
  • Insert a funnel into the transmission dipstick tube.
  • Pour in the recommended transmission fluid (check owner’s manual for type and capacity).
• Check Level:
  • Start the engine and let it run for a few minutes.
  • Shift through all gears and check the fluid level on the dipstick, adding more fluid if necessary.
