Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and set the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Change Transmission Fluid

Tools Required: Socket set, fluid pump, drain pan.
Remove the transmission pan bolts and carefully lower the pan to drain the old fluid.
Inspect the transmission pan for metal debris and clean it thoroughly.
Replace the transmission filter with a new one.
Reinstall the pan with a new gasket, tightening bolts to the manufacturer’s specified torque.
Refill the transmission with the recommended fluid type through the dipstick tube.

3. Inspect and Replace Throttle Position Sensor (if necessary)

Tools Required: Multimeter, socket set.
Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the sensor.
Use a multimeter to test the sensor according to the specifications in the repair manual.
If faulty, install a new throttle position sensor and reconnect the electrical connector.

4. Check and Repair Transmission Cooler Lines

Tools Required: Wrench set, fluid line disconnect tool.
Inspect the transmission cooler lines for any signs of leaks or damage.
If leaks are found, replace the damaged lines with new ones.
Ensure all connections are secure and leak-free.
