Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, rags.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using jack stands to access the transmission pan.
2. Place a drain pan under the transmission pan and remove the drain plug.
3. Allow the old transmission fluid to completely drain.
4. Replace the drain plug and torque to the manufacturer’s specifications.
5. Remove the transmission dipstick and use a funnel to add new, compatible transmission fluid until it reaches the appropriate level.

3. Inspect and Repair Transmission Linkage

Sub-steps:
1. Visually inspect the transmission linkage for bent or broken components.
2. If any parts are damaged, remove them using a socket set and replace with new components.
3. Reattach the linkage, ensuring it is aligned properly and secured.

4. Replace Gear Selector Position Sensor (if faulty)

Sub-steps:
1. Locate the gear selector position sensor on the transmission.
2. Disconnect the wiring harness from the sensor.
3. Remove the mounting bolts with a socket set and carefully take out the old sensor.
4. Install the new sensor in the same position, securing it with bolts, and reconnect the wiring harness.

5. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and test the transmission by shifting through all gears to ensure proper operation.
