Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission funnel, fluid catch pan, socket set.
Remove the transmission fluid dipstick and check the fluid level.
If low, drain the old fluid into a catch pan.
Replace with manufacturer-recommended transmission fluid using a funnel.
Reinsert the dipstick and ensure it is seated properly.

3. Inspect and Replace Transmission Range Sensor

Tools Required: Socket set, multimeter, new transmission range sensor.
Locate the transmission range sensor on the transmission.
Disconnect the electrical connector.
Unbolt the sensor from its housing and remove it.
Install the new transmission range sensor and secure it with bolts.
Reconnect the electrical connector.

4. Inspect Transmission Linkage and Cables

Tools Required: Socket set.
Locate the transmission linkage and cables.
Check for any visible wear, corrosion, or disconnection.
If any components are damaged, replace them.
Adjust the linkage as per vehicle specifications.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for any warning lights.
Attempt to shift through the gears to ensure proper operation.
