Partial oil change in automatic transmission
Materials:
*Automatic transmission oil (check your owner’s manual for recommended type and volume)
* Oil filter (optional)
* Oil pan gasket (optional)
* Funnel
* Wrench
* Pallet
Steps:
1. Prepare the car
* Place the car on a level surface.
*Place the gear shift lever in Park (P) position.
* Stop the engine and let it cool.
2. Identify the drain plug
* Locate the drain plug on the transmission oil pan.
3. Drain the oil
* Place a drain pan under the drain plug.
* Carefully unscrew the drain plug with a wrench.
* Drain the oil until it stops leaking.
* Screw the drain plug back in using a new seal if necessary.
4. Replace oil filter (optional)
*If your vehicle has a replacement oil filter, locate it and replace it with a new one.
5. Replace the oil pan gasket (optional)
*If your oil pan gasket looks damaged or worn, replace it with a new one.
6. Fill with new oil
* Using a funnel, pour new oil into the transmission dipstick hole.
* Fill the required amount of oil according to the instructions in the owner’s manual.
7. Check oil level
* Remove the transmission dipstick and wipe it clean.
* Insert the dipstick back and remove it again.
* Check the oil level on the dipstick. It should be between the “min” and “max” marks.
8. Start the engine
* Start the engine and let it idle for a few minutes.
* Shift through all gears to distribute the new oil.
9. Check the oil level again
*Repeat step 7 to check the oil level. Add oil if necessary.
Notes:
*A partial oil change removes only part of the old oil. For a more complete replacement, the transmission may need to be flushed.
*Always read your owner’s manual for instructions specific to your specific vehicle.
*If you are unsure of any steps, consult a qualified mechanic for assistance.
