1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on the vehicle.
Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, screwdrivers.

2. Addressing Engine Misfires

Replace Spark Plugs:
- Remove the engine cover if necessary.
- Disconnect the ignition coils and remove the old spark plugs using a socket wrench.
- Install new spark plugs, ensuring they are gapped correctly as per manufacturer specifications.
- Reconnect ignition coils and engine cover.
Check and Replace Ignition Coils:
- If misfires persist, test ignition coils with a multimeter.
- Replace any faulty coils with new ones, following the same removal and installation procedure as spark plugs.

3. Inspecting and Replacing Engine Mounts

Locate the engine mounts and inspect for cracks or excessive wear.
To replace:
- Support the engine with a jack and a wooden block to avoid damage.
- Remove the fasteners securing the old engine mount.
- Install the new mount and torque to the manufacturer's specifications.
- Repeat for any additional mounts as necessary.

4. Transmission Fluid Check and Replacement

Check Fluid Level:
- With the vehicle running and in park, check the transmission fluid level using the dipstick.
- If low, add the appropriate type of transmission fluid as specified in the owner's manual.
Change Transmission Fluid:
- Place a drain pan under the transmission pan and remove the drain plug.
- Allow fluid to drain completely, then replace the drain plug.
- Remove the transmission pan, replace the filter, and reinstall the pan with new gasket and torque to specifications.
- Refill with new transmission fluid through the dipstick tube.
