1. Preparation

Gather required tools and parts.
Tools Required:
- Socket set
- Funnel
- Clean cloth
- Torque wrench
Parts Required:
- New transmission fluid (check manufacturer specifications for type)
- New transmission filter (if applicable)

2. Drain Old Transmission Fluid

Raise the vehicle using jack stands.
Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and allow the fluid to drain completely.
Inspect the old fluid for metal shavings or contaminants.

3. Replace Transmission Filter (if applicable)

Remove the old transmission filter by unscrewing it or pulling it off.
Clean the filter mounting area on the transmission.
Install the new filter, ensuring it is securely attached.

4. Install Transmission Pan

Clean the transmission pan and remove old gasket material.
Place a new gasket or apply a gasket sealant as per manufacturer instructions.
Reattach the transmission pan and tighten the bolts to the recommended torque specification (typically around 8-10 Nm).
Ensure no leaks are present at the seams.

5. Fill New Transmission Fluid

Locate the fill plug on the transmission.
Using a funnel, pour new transmission fluid into the fill hole until it reaches the appropriate level on the dipstick or overflow begins to discharge from the fill hole.
Start the engine and cycle through the gears while keeping an eye on the fluid level, adding more fluid if necessary.
