why does my Honda Pilot YF3 (2016-2022) transmission slip during acceleration

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and set the parking brake.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, drain pan, funnel.
• Sub-steps:
  1. Remove the transmission fluid dipstick and check fluid level.
  2. If the fluid is low, add the appropriate Honda ATF DW-1 fluid.
  3. If the fluid is dark or smells burnt, proceed to drain and replace it.
  4. Place a drain pan under the transmission, remove the drain plug, and allow fluid to fully drain.
  5. Replace the drain plug with a new washer and torque it to manufacturer specifications (usually around 12 lb-ft).
  6. Refill the transmission with new fluid using a funnel and check the level with the dipstick.

3. Inspect and Replace Transmission Filter

• Tools Required: Socket set, new transmission filter, gasket, and sealant.
• Sub-steps:
  1. Remove the transmission pan by unscrewing the bolts (torque specifications may vary).
  2. Carefully lower the pan and clean the mating surface on the transmission.
  3. Remove the old filter and install the new filter, ensuring it is properly seated.
  4. Apply sealant to the new gasket and install it on the pan.
  5. Reinstall the transmission pan and torque bolts to specifications (usually around 10 lb-ft).

4. Inspect Transmission Control Module (TCM)

• Tools Required: OBD-II scanner, multimeter.
• Sub-steps:
  1. Reconnect the battery and use the OBD-II scanner to check for any TCM-related codes.
  2. If codes are present, follow the manufacturer’s troubleshooting guide to diagnose and repair.
  3. If necessary, replace the TCM with a new unit, ensuring all connections are secure.
