Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, transmission fluid, funnel, torque wrench, and replacement parts if necessary.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Check Transmission Fluid

Locate the transmission dipstick (if equipped) or access the fluid fill plug.
Remove the dipstick or fill plug and wipe it clean.
Reinsert and remove to check the fluid level; add fluid if low.
If the fluid is dark or has a burnt smell, proceed to change it.

3. Change Transmission Fluid

Place a drain pan under the transmission pan.
Remove the bolts securing the transmission pan using a socket set.
Gently pry the pan loose and allow the old fluid to drain completely.
Clean the pan and magnet (if equipped) of any debris before reassembly.
Replace the transmission filter if applicable.
Reinstall the pan with a new gasket and torque bolts to manufacturer specifications.

4. Inspect and Replace Transmission Control Module (if necessary)

Remove any covers obstructing access to the TCM.
Unplug the electrical connector and remove the TCM from its mounting.
Replace with a new or refurbished TCM.
Reconnect the electrical connector and reinstall any covers.

5. Reconnect Battery and Test

Reconnect the battery terminal securely.
Start the engine and allow it to warm up.
Test the transmission engagement by shifting through all gears.
