- Place a drain pan under the transmission pan.
- Remove the drain plug or the transmission pan bolts to let the fluid drain completely.
Replace Filter (if applicable):
- Remove the transmission pan completely.
- Replace the transmission filter and gasket.
Add New Transmission Fluid:
- Use the manufacturer-recommended transmission fluid.
- Pour fluid through the dipstick tube until it reaches the proper level.

3. Inspect and Replace Transmission Mounts

Locate the Transmission Mounts: Identify the mounts securing the transmission.
Check for Damage: Look for any signs of wear, cracks, or separation.
Remove Old Mounts:
- Support the transmission with a jack.
- Remove bolts securing the mounts to the body and the transmission.
Install New Mounts:
- Position the new mounts and secure them with bolts.
- Torque bolts to manufacturer specifications.

4. Test Drive the Vehicle

Reconnect the battery.
Start the engine and allow it to warm up.
