Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical issues.

2. Fluid Change and Filter Replacement

Drain Transmission Fluid
- Place a drain pan under the transmission pan.
- Remove the drain plug and allow fluid to drain completely.
Replace Transmission Filter
- Remove the transmission pan bolts using a socket set.
- Carefully detach the pan, taking care not to damage the gasket.
- Remove the old filter and install a new filter.
Install New Gasket
- Clean the mating surfaces of the transmission pan and transmission housing.
- Install a new gasket on the transmission pan.
Reinstall Transmission Pan
- Reattach the pan using the socket set, ensuring that the bolts are tightened to the manufacturer’s torque specifications (typically around 8-10 Nm).
Refill Transmission Fluid
- Use a funnel to refill the transmission with the specified fluid type (check owner's manual for fluid specifications).
- Start the engine and cycle through the gears, then check the fluid level again and adjust as necessary.

3. Inspect and Replace Transmission Mounts (if necessary)

Remove Old Mounts
- Secure the vehicle on jack stands and remove the bolts securing the transmission mounts.
- Carefully lift the transmission slightly to relieve pressure on the mounts.
Install New Mounts
- Position the new mounts in place and secure them with the bolts.
- Torque the bolts to manufacturer specifications.
