Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, torque wrench, transmission fluid, shop rags.
Lift the vehicle safely using jack stands and ensure it is level.

2. Check and Replace Transmission Fluid

Sub-step 1: Remove the transmission fluid dipstick and check the fluid level. If it's low, add the recommended type of transmission fluid.
Sub-step 2: If the fluid is dirty or smells burnt, drain the transmission fluid by removing the drain plug.
Sub-step 3: Replace the drain plug and refill with new transmission fluid through the dipstick tube, using a funnel.
Sub-step 4: Start the engine and let it reach operating temperature, then check the fluid level again and adjust if necessary.

3. Inspect and Adjust Shift Linkage

Sub-step 1: Locate the shift linkage under the vehicle and visually inspect for any loose or damaged components.
Sub-step 2: Adjust the shift linkage if necessary, ensuring it aligns properly with the transmission.
Sub-step 3: Tighten any loose bolts to the manufacturer's specifications.

4. Replace Transmission Control Module (if necessary)

Sub-step 1: Disconnect the vehicle battery to prevent electrical shorts.
Sub-step 2: Remove the cover and access the TCM located on the transmission.
Sub-step 3: Disconnect the wiring harness and remove the TCM mounting bolts.
Sub-step 4: Install the new TCM by reversing the removal process and reconnect the battery.
