how to troubleshoot Honda CR-V Fifth Generation (2017-2022) transmission jerking

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, fluid catch pan, funnel, torque wrench.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts while working on the vehicle.

2. Transmission Fluid Change

1. Drain Fluid

   • Place a fluid catch pan under the transmission pan.
   • Remove the transmission pan bolts using a socket wrench and carefully lower the pan to drain the old fluid.
   • Discard the old fluid responsibly.

2. Replace Filter

   • Remove the old transmission filter and inspect it for metal shavings or debris.
   • Install a new transmission filter, ensuring it is securely in place.

3. Inspect and Clean Pan

   • Clean the transmission pan with a suitable solvent.
   • Inspect the magnet inside the pan for metal shavings; clean it if necessary.

4. Reinstall Pan

   • Apply a new gasket or sealant to the transmission pan.
   • Torque the pan bolts to the manufacturer’s specifications, typically around 8-12 ft-lbs.

5. Refill Transmission Fluid

   • Using a funnel, refill the transmission with the recommended fluid type (typically Honda ATF DW-1) through the dipstick tube.
   • Check fluid levels with the engine running and add fluid as necessary.

3. Sensor Inspection and Replacement (if needed)

1. Throttle Position Sensor (TPS)

   • Disconnect the electrical connector from the TPS.
   • Use a multimeter to test the resistance and voltage output according to the service manual specifications.
   • Replace the TPS if any readings are outside of the specified range.

2. Vehicle Speed Sensor (VSS)

   • Locate the VSS on the transmission.
   • Disconnect the electrical connector and remove the sensor.
   • Test the sensor with a multimeter and replace if it fails to meet specifications.
