my Honda CR-V’s transmission is slipping, what are the possible causes

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative battery terminal to avoid electrical issues.

2. Check and Replace Transmission Fluid

• Sub-steps:
  • Locate the transmission dipstick and remove it to check fluid level.
  • If low, add the recommended type of transmission fluid.
  • If the fluid is dark or has a burnt smell, perform a fluid change.
  • Tools Required: Funnel, transmission fluid.

3. Inspect and Replace Transmission Filter

• Sub-steps:
  • Remove the transmission pan using a socket set; drain old fluid into a suitable container.
  • Replace the transmission filter and gasket.
  • Reinstall the transmission pan, ensuring proper torque specifications are met (typically 10-12 ft-lbs).
  • Tools Required: Socket set, torque wrench, new filter and gasket.

4. Assess and Adjust Throttle Position Sensor

• Sub-steps:
  • Disconnect the connector from the TPS.
  • Use a multimeter to check the TPS voltage (should be around 0.5V at idle).
  • If out of specification, adjust or replace the TPS as needed.
  • Tools Required: Multimeter, screwdriver.

5. Test Drive and Monitor

• Sub-steps:
  • Reconnect the battery.
  • Start the vehicle and perform a test drive to check for slipping and shifting issues.
  • Monitor the transmission behavior and ensure no warning lights are illuminated.
