Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts.

2. Check and Change Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick: Remove the dipstick and wipe it clean.
2. Check fluid level: Insert the dipstick back into the tube and remove to check the fluid level.
3. Drain old fluid: Place a drain pan under the transmission, remove the drain plug, and allow the fluid to drain completely.
4. Replace the filter: Remove the transmission pan, replace the filter, and clean the pan before reinstalling.
5. Refill with new fluid: Insert a funnel into the dipstick tube and pour in the correct type and amount of new transmission fluid (consult the owner's manual for specifications).

3. Inspect and Replace Transmission Range Sensor

Sub-steps:
1. Disconnect the battery: Remove the negative terminal to avoid electrical shorts.
2. Locate the range sensor: Find the transmission range sensor near the transmission housing.
3. Remove the sensor: Disconnect the wiring harness and unscrew the sensor from its mount.
4. Install the new sensor: Position the new sensor and secure it with screws, reconnect the wiring harness.
5. Reconnect the battery: Reattach the negative terminal.

4. Test Drive the Vehicle

Take the vehicle for a test drive to ensure smooth shifting and to check for any remaining issues.
