2. Insert the dipstick back into the tube and remove it again to check fluid level.
3. If fluid is low, add the manufacturer-recommended transmission fluid (consult the owner's manual for specifications).
4. If fluid is burnt, proceed to drain and replace.

3. Drain Transmission Fluid

Sub-steps:
1. Place a drain pan beneath the transmission pan.
2. Remove the transmission fluid pan bolts using a socket set.
3. Carefully lower the pan and allow the old fluid to drain completely.

1. Remove the old transmission filter and discard it.
2. Clean the transmission pan and the sealing surface on the transmission.
3. Install the new transmission filter and secure it in place.
4. Place a new gasket on the transmission pan.

5. Reassemble and Refill

Sub-steps:
1. Reattach the transmission pan and tighten the bolts to the specified torque settings (check the service manual for specifications).
2. Refill the transmission with new fluid through the dipstick tube, using a funnel.
3. Start the engine and let it idle; shift through all gears while checking for leaks.
