why does my Honda Accord 9th Generation (2013-2017) transmission jerk when accelerating

Solution

1. Preparation

• Gather tools and materials: OBD-II scanner, socket set, transmission fluid, fluid pump, and safety gear.
• Park the vehicle on a level surface and engage the parking brake.

2. Check and Replace Transmission Fluid

1. Locate the Transmission Dipstick: Remove the dipstick to check the fluid level.
2. Inspect Fluid Condition: If the fluid is dark or smells burnt, it needs replacement.
3. Drain Old Fluid: Place a drain pan under the transmission pan, remove the transmission fluid pan bolts, and allow fluid to drain completely.
4. Replace Filter: Remove the old transmission filter and install a new one.
5. Reinstall Transmission Pan: Clean the mating surfaces and install a new gasket; torque the bolts to manufacturer specifications (usually around 12-15 ft-lbs).
6. Refill with New Fluid: Use a fluid pump to refill the transmission with the appropriate type of fluid (typically Honda ATF DW-1).

3. Inspect and Repair Electrical Connections

1. Check Wiring Harness: Visually inspect the wiring harness for any signs of wear or corrosion.
2. Reconnect Loose Connectors: Ensure all connectors are securely fastened and check for any damaged wires.
3. Test Electrical Components: Use a multimeter to test the transmission solenoids for proper operation.

4. Replace Worn Engine/Transmission Mounts (if applicable)

1. Lift Vehicle: Use a jack and jack stands to safely lift the vehicle.
2. Remove Mount Bolts: Locate the damaged mounts and remove the bolts securing them to the frame and transmission.
3. Install New Mounts: Position the new mounts and secure them with bolts; torque to manufacturer specifications.
