my Honda Civic 10th Generation (2016-2021) transmission slips when shifting gears

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to prevent electrical shorts.
• Ensure the vehicle is on a level surface and securely raise it with jack stands.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission funnel, catch pan, socket set, torque wrench.
• Drain the old transmission fluid using a catch pan. Remove the transmission pan bolts and carefully lower the pan.
• Inspect the pan for metal debris and clean it thoroughly.
• Replace the transmission filter if applicable.
• Reinstall the pan with a new gasket, tightening bolts to manufacturer specifications.
• Refill the transmission with the appropriate type and amount of new fluid (consult owner’s manual for specifications).

3. Inspect and Replace Transmission Solenoids (if faulty)

• Tools Required: Socket set, multimeter.
• Locate the transmission assembly and access the solenoids.
• Disconnect the electrical connector from the solenoid and remove it.
• Test the solenoid with a multimeter to ensure it operates within specifications.
• If faulty, replace with a new solenoid and reconnect.

4. Reconnect Battery and Test

• Reconnect the battery terminals.
• Start the engine and allow it to reach operating temperature, then check for leaks.
• Test drive the vehicle to ensure smooth shifting and verify that the slipping issue is resolved.
