Learn how to diagnose and fix transmission jerking in Honda Civic 10th Generation (2016-2021). Step-by-step guide with symptoms, diagnostics, and solutions.

Affected Component

Transmission

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow the engine to cool before draining transmission fluid to avoid burns.

Symptoms

•Jerking or harsh shifting between gears
•Delay in engagement when shifting from park to drive/reverse
•Check engine light may be illuminated
•Poor acceleration or loss of power during shifts
•Unusual noises (clunking or grinding) when shifting gears

Diagnostic Steps

1
Scan the vehicle's onboard diagnostic system using an OBD-II scanner to check for any error codes related to the transmission.
2
Inspect transmission fluid level and condition; look for burnt smell or dark color.
3
Check for fluid leaks around the transmission pan and seals.
4
Verify if there are any software updates available for the transmission control module (TCM).
5
Conduct a visual inspection of the transmission mounts for signs of wear or damage.
6
Test the throttle position sensor (TPS) for proper operation using a multimeter.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with jack stands if necessary.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Check and Replace Transmission Fluid

Remove the transmission fluid dipstick and check the fluid level.
If the fluid is low or appears burnt, drain the old fluid using a fluid pump.
Replace with recommended transmission fluid (check owner's manual for specifications).
Refill the transmission with new fluid through the dipstick tube.
Start the engine and run through all gears to circulate the fluid, then check the level again and adjust as necessary.

3. Inspect and Replace Transmission Control Module (if applicable)

If diagnostic steps indicate issues with the TCM, locate it (often found near the transmission).
Disconnect the electrical connector and remove the module using the appropriate socket.
Install the new TCM following the manufacturer’s instructions.
Reconnect the electrical connector and reattach the negative battery terminal.

4. Update Transmission Software

If applicable, connect a compatible diagnostic tool to the OBD-II port.
Follow the manufacturer's instructions to check for and install any software updates for the TCM.

5. Test Drive

After completing repairs, perform a test drive to verify that the shifting is smooth and the jerking has been resolved.
