how to troubleshoot transmission jerking in Honda Accord 9th Generation (2013-2017)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and wipe it clean; reinsert and check the fluid level.
3. If low, use a funnel to add the appropriate Honda ATF (automatic transmission fluid) until it reaches the correct level.
4. If the fluid is dark or burnt, proceed with a fluid change.
5. Drain the old transmission fluid using a wrench on the drain plug and allow it to fully empty.
6. Replace the drain plug with a new gasket and tighten to manufacturer specifications (typically around 25 lb-ft).
7. Refill with fresh Honda ATF through the dipstick tube or fill plug.

3. Inspect and Replace Transmission Mounts (if necessary)

1. Locate the transmission mounts; typically found near the transmission casing.
2. Visually inspect for cracks or excessive wear.
3. If damaged, use a socket set to remove the bolts securing the mounts.
4. Replace with new mounts, ensuring they align properly.
5. Torque the bolts to the manufacturer’s specifications.

4. Inspect and Test Electrical Components

1. Check the wiring harness connected to the TCM for any signs of wear, corrosion, or loose connections.
2. If any issues are found, repair or replace the damaged wires or connectors.
3. Test the throttle position sensor (TPS) and mass air flow (MAF) sensor using a multimeter to ensure they are functioning within specs.
4. Replace any faulty sensors as needed.
