Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Address Engine Misfires

Inspect and Replace Spark Plugs
- Remove the ignition coils using a socket set.
- Unscrew the old spark plugs using a spark plug socket.
- Install new spark plugs, ensuring proper gap settings as per manufacturer specifications.
- Reattach the ignition coils.

3. Check and Change Transmission Fluid

Inspect Fluid Level
- Locate the transmission dipstick.
- Remove the dipstick and wipe it clean, then reinsert it and check the fluid level.
Change Transmission Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan.
- Clean the pan and replace the filter if applicable.
- Reinstall the pan with a new gasket and torque to manufacturer specifications.
- Fill the transmission with new fluid through the dipstick tube.

4. Inspect Engine Mounts

Visual Inspection
- Check for cracked or worn mounts.
Replace Damaged Mounts
- Support the engine with a jack (using a block of wood to avoid damage).
- Remove the bolts securing the damaged mount, then replace with a new mount and torque to specifications.

5. Inspect Drive Shafts and CV Joints

Visual Check
- Look for any tears in the CV boot or signs of grease leakage.
Replace if Necessary
- Remove the axle nut and disconnect the drive shaft from the transmission side.
- Install a new drive shaft or CV joint as needed, ensuring proper torque on the axle nut.
