2. Check and Change Transmission Fluid

Check Fluid Level:
- Start the engine and let it warm up to operating temperature.
- With the engine running, pull the transmission dipstick and wipe it clean.
- Reinsert the dipstick and pull it out again to check the fluid level.
- If low, add the appropriate type of transmission fluid.
Change Fluid (if contaminated):
- Place a drain pan under the transmission.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan to avoid spilling fluid.
- Replace the transmission filter if applicable.
- Clean the pan and replace the gasket.
- Reinstall the pan and torque bolts to the manufacturer's specification.
- Refill with new transmission fluid through the dipstick tube.

3. Inspect and Replace Transmission Mounts (if needed)

Check Mounts:
- Visually inspect the transmission mounts for cracks or excessive wear.
- Use a jack to support the transmission if necessary.
Replace Mounts:
- Remove the bolts securing the mounts to the transmission and the frame.
- Install new mounts and torque the bolts to the specified value.

4. Test and Replace Solenoids (if needed)

Remove Transmission Pan:
- Follow the steps in "Change Fluid" to access the solenoids.
Inspect and Replace Solenoids:
- Disconnect the electrical connectors from the solenoids.
- Remove the solenoids from their mounting positions.
- Install new solenoids and reconnect the wiring.
