Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and safely supported (use jack stands if needed).
• Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, catch pan.
• Remove the transmission fluid dipstick, and check if the fluid is at the correct level.
• If low, add the appropriate fluid type (check owner's manual for specifications).
• If the fluid is burnt or contaminated, proceed to replace it.
  • Position a catch pan under the transmission pan.
  • Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
  • Replace the transmission filter if applicable.
  • Clean the transmission pan and replace the pan gasket.
  • Reinstall the pan and torque the bolts to manufacturer specifications.

3. Inspect and Replace Components

• Tools Required: Socket set, torque wrench, multimeter.
• Inspect the throttle position sensor using a multimeter to ensure it is sending the correct signals.
• If faulty, replace the throttle position sensor.
  • Disconnect the electrical connector and remove the mounting screws.
  • Install the new sensor and reconnect the electrical connector.

4. Test Transmission Operation

• Reconnect the battery and start the engine.
• Allow the vehicle to warm up and then take it for a test drive to ensure proper shifting and no slipping occurs.
