why does my Honda Civic 9th Generation (2012-2015) transmission slip when accelerating

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to prevent electrical shorts.
• Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Remove the transmission fluid dipstick and check the fluid level.
  2. If fluid is low, use a funnel to add the appropriate Honda ATF DW-1 fluid until it reaches the full mark.
  3. If fluid is contaminated, proceed to drain and replace the fluid.
  4. Place a drain pan under the transmission and remove the drain plug (if equipped) to drain old fluid.
  5. Replace the drain plug and torque it to the manufacturer’s specifications.
  6. Refill the transmission with new fluid through the dipstick tube.

3. Inspect and Replace Transmission Filter (if applicable)

• Sub-steps:
  1. Remove the transmission pan by loosening bolts and carefully prying it off.
  2. Inspect the old filter and replace it with a new one.
  3. Clean the transmission pan thoroughly and replace the gasket if necessary.
  4. Reinstall the transmission pan and torque bolts to manufacturer specifications.

4. Inspect Transmission Control Module (TCM)

• Sub-steps:
  1. Locate the TCM and disconnect the electrical connector.
  2. Inspect the connector for corrosion or damage and clean if necessary.
  3. Reconnect the TCM and ensure all connections are secure.
  4. If problems persist, consider replacing the TCM with a compatible part.
