Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool down if it has been running.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, transmission fluid.
Drain the old transmission fluid using a transmission drain pan.
Replace the transmission fluid filter if applicable.
Refill with the manufacturer-recommended transmission fluid until it reaches the appropriate level.

3. Inspect and Replace Transmission Range Sensor

Tools Required: Socket set, multimeter, replacement transmission range sensor.
Locate the transmission range sensor, typically mounted on the transmission.
Disconnect the electrical connector and remove the mounting bolts for the sensor.
Install the new range sensor and reconnect the electrical connector.
Test the sensor operation using a multimeter before finalizing installation.

4. Inspect and Adjust Throttle Position Sensor

Tools Required: Socket set, multimeter.
Locate the throttle position sensor, typically on the throttle body.
Disconnect the electrical connector and measure voltage output with a multimeter while moving the throttle.
If the voltage output is outside the specified range, replace the TPS.
