Tools Required: Funnel, new transmission fluid (consult owner's manual for specifications).
Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, remove it again, and check the fluid level.
If low, add the appropriate type of transmission fluid to the fill tube until the correct level is reached.

3. Inspect and Repair Shift Linkage

Tools Required: Socket set, wrenches, screwdrivers.
Visually inspect the shift linkage and cables for damage.
If damaged, remove the old linkage using the socket set and replace it with a new part.
Adjust the linkage according to manufacturer specifications.

4. Replace Transmission Control Module (if necessary)

Tools Required: OBD-II scanner, socket set.
If diagnostic codes indicate a TCM issue, locate the TCM in the vehicle.
Disconnect the wiring harness from the TCM and remove the mounting bolts.
Install the new TCM and reconnect the wiring harness.
