Step 2: Disconnect the Battery

Safety is crucial when working with electrical components. Follow these steps to disconnect the battery:

Step 3: Locate the TCM

Next, you need to find the Transmission Control Module. The TCM is typically located:

• Under the dashboard on the driver's side.

1. Locate the screws or clips holding the kick panel in place.
2. Use a Phillips screwdriver or a socket to remove these fasteners.
3. Gently pull the kick panel away from the dashboard.

Step 5: Disconnect the Wiring Harness

Once the kick panel is removed, you can access the TCM. Follow these steps:

1. Identify the wiring harness connected to the TCM.
2. Press the release tab on the connector and pull it straight out to disconnect.
3. Inspect the connector for any damage or corrosion.

Step 6: Remove the Old TCM

With the wiring harness disconnected, proceed to remove the old TCM:

1. Use a socket to remove the bolts securing the TCM in place. These are usually 10mm or 13mm bolts.
2. Carefully pull the TCM out of its mounting location.
3. Dispose of the old TCM properly.

Step 7: Install the New TCM

Now, it's time to install the new TCM:

1. Position the new TCM in the same location as the old one.
2. Secure it with the bolts you removed earlier; tighten them to the manufacturer’s specifications using a torque wrench.
3. Reconnect the wiring harness, ensuring it clicks into place securely.

Step 8: Reattach the Kick Panel

After installing the new TCM, you need to reassemble the kick panel:

1. Align the kick panel back into place.
2. Reinstall the screws or clips you removed earlier.
3. Ensure the panel is securely attached.

Step 9: Reconnect the Battery

To complete the installation, reconnect the battery:

1. Attach the negative (-) terminal back to the battery.
2. Tighten the connection with a 10mm socket.
