I see him talking about a Drain Plug Washer... have you seen this for sale online/ is it possible that my original one is fine and doesn't need replaced?

Thanks.

AUTOMATIC TRANSAXLE

Fluid capacity (drain and refill), L (qt.,

Fluid type:
Toyota Genuine ATF Type WS

Change automatic transmission fluid only
as necessary.

Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”. When
changing the automatic transmission fluid,
use only “Toyota Genuine ATF Type WS”
(ATF JWS3324 or NWS9638) to aid in
assuring maximum transaxle performance.
Notice: Using automatic transmission
fluid other than “Toyota Genuine ATF
Type WS” may cause deterioration in
shift quality, locking up of your transmission
accompanied by vibration, and
ultimately damage the automatic transmission
of your vehicle.
Please contact your Toyota dealer for further
details.


I looked at the “Scheduled Maintenance Guide.” It never says when to change but it says when to check it. It says to check it pretty often.

I have 100K miles on my Yaris now. I bought it with 50K and don't know if the fluid was ever changed. I used the dipstick and saw the level was good. The color was purple, but a little dark. No metallic flakes or anything. I have no problems shifting (automatic).

Is it bad for the fluid to be a little dark?
Is there a good reason for me to change the fluid or even clean the filter and change the gasket as this website below instructs? (I know how much to use and to only use Toyota fluid.)

When checking transmission fluid level, should car be in park or neutral while running?

Shouldn't that be listed on the transmission dipstick?

IMO...no....unless the vehicle has been in a flood or subjected to unusually harsh operating conditions like trailer towing, subzero operation, or very hot climate.

I check my level once a year and inspect the transmission for leaks while up on ramps for oil changes.

And of course my question is... Flush the filter with brake cleaner? Do the Toyota filters no run a paper element? I saw the foam in the pic but is that all that is in there? Just wondering out loud.

Go purchase Toyota WS fluid plus one more court than your car will hold.
1. Drain the pan.
2. Refill the pan with exactly the same amount you drained.
3. Locate and remove the fluid return line from cooler to transmission.
3. Remove it and drain into graduated container.
4. Start the car, drain out the balance of the fluid as you add the new fluid.
5. Reconnect the return line, top off the fluid to proper level.
(As an added benifit you can also change the filter if the fluid is really dirty and burnt).
This will get most of the fluid out of the car cost effectively.

Here's my 2 cents:

After filling up the transmission fluid, I went to measure if I had put enough. The mechanic's manual tells us to measure the fluid level while the engine is running at a normal operating temperature (see image below), set on Park, and while the car is level. The latter is very important and will have a significant effect on your fluid level readings. Here's the experiment I did:

Parked on the left side of the street, the car was rolling a few degrees left. The ATF level would read below the normal quantity.

Parked on the right side of the street, the car was rolling a few degrees right. The ATF level would read above the normal quantity.

I wouldn't believe such a small inclination change would have that much of an effect on the ATF level, so I repeated my experiment to convince myself it was real. The neighbors must have tought I was crazy...

Here's the official instructions for fluid level check on a 2007 yaris:
