my Honda Pilot YF3 (2016-2022) has a rough transmission, what to do?

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical shorts during the repair.

2. Transmission Fluid Change

1. Drain Old Fluid:

   • Locate the transmission fluid drain plug and place a drain pan underneath.
   • Remove the drain plug and allow the old fluid to fully drain.
   • Reinstall the drain plug and torque to manufacturer specifications.

2. Replace Transmission Filter:

   • Remove the transmission pan by unbolting it; be careful as fluid may still be in the pan.
   • Remove the old filter and replace it with a new one.
   • Clean the transmission pan and ensure the sealing surface is free from debris.

3. Add New Fluid:

   • Reinstall the transmission pan with a new gasket or sealant, torquing bolts to the specified values.
   • Use a funnel to add the appropriate type of new transmission fluid through the dipstick tube.
   • Start the engine and cycle through the gears while checking the fluid level.

3. Inspect and Test TCM

1. Visual Inspection:

   • Check the wiring and connectors to the TCM for any signs of damage or corrosion.

2. Test TCM Functionality:

   • Use a multimeter to test voltage and ground signals to the TCM.
   • If the TCM is malfunctioning, replace it with a new unit as per manufacturer's specifications.
