2. If low, drain the old transmission fluid using a fluid pump.
3. Replace with the manufacturer-recommended transmission fluid (consult owner's manual for specifications).
4. Reinstall the dipstick or fill plug and ensure it is secure.

3. Inspect and Replace Transmission Mounts

Tools Required: Socket set, pry bar.
Sub-steps:
1. Locate the transmission mounts and inspect for cracks or separation.
2. If damaged, remove the bolts securing the mounts to the transmission and chassis.
3. Install new mounts by aligning them properly and torquing to manufacturer's specifications.

4. Reprogram or Replace TCM (if necessary)

Tools Required: OBD-II scanner, computer with TCM software.
Sub-steps:
1. Connect the OBD-II scanner to read any TCM-related error codes.
2. Follow manufacturer instructions to reprogram or update the TCM software.
