Sub-steps:
- Locate the transmission linkage (usually connected to the shifter).
- Visually inspect for any signs of wear or damage.
- If damaged, replace the linkage with a new part.
- Adjust the linkage according to manufacturer specifications if misaligned.

4. Inspect and Replace Transmission Filter (if applicable)

Sub-steps:
- Remove the transmission pan (if equipped) by unscrewing the bolts.
- Carefully lower the pan and remove the old filter.
- Install the new filter and reattach the pan with a new gasket.
- Torque the pan bolts to manufacturer specifications.

5. Reconnect Battery and Test

Reconnect the battery terminals.
