Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, torque wrench, fluid pump, and multimeter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical shorts.

2. Check and Replace Transmission Fluid

Remove the transmission fluid dipstick and check the fluid level.
If low, use a fluid pump to add the correct type of transmission fluid (consult owner's manual for specifications).
If the fluid is dirty or smells burnt, drain the transmission fluid using a drain pan.
Replace the fluid filter if applicable and refill with fresh transmission fluid.
Recheck the fluid level and ensure it is within the proper range.

3. Inspect Transmission Linkage

Locate the transmission linkage and inspect for any signs of wear or damage.
Tighten any loose connections using a socket set.
If damaged, replace the linkage assembly.

4. Check Electrical Connections

Inspect the battery connections for corrosion and ensure they are tight.
Use a multimeter to check the battery voltage; it should be around 12.6 volts.
If voltage is low, charge or replace the battery as necessary.

5. Update Transmission Software

Connect the OBD-II scanner to the vehicle and check for available software updates.
Follow the manufacturer's instructions to complete any necessary updates to the TCM software.
Clear any fault codes and test the vehicle.
