2013 Toyota Sienna Limited AWD - Transmission Fluid Replacement

[@BigDipper79]

Excellent video. I have a 2012 RX350 AWD it has the same Transmission. Plan on doing the same thing. Thanks.

You’re welcome!

Never assume whats inside the transmission is the correct level unless you bought the car new. It might be overfilled by a previous mechanic. I would leave the drain plug out and the plastic straw in. When you refill with fresh fluid, any extra fluid will leak out the plastic overflow tube. This is the correct amount.

[@PTranProductions]

Yes, this estimated method on transmission that never been serviced before and assuming correct level filled from the factory. Your method is only correct if the transmission fluid temperature is between 35 & 45 °C (that’s how’s it’s supposed to be done with a Toyota Techstream and transmission put into special mode). If you do it when the fluid at room temperature, you are overfilling your transmission. That’s because when that fluid gets heated up to 35°C and above, it will expand which gives more volume.

Thank you for this video. Have you noticed any issues with the transmission after changing the fluid? I have a 2013 Sienna that never been serviced before for transmission fluid. I am hesitating to change the fluid as other people are advising to not do it if the transmission has never been serviced before and the mileage is over 100,000 KM. Can you please share your experience? Thanks.

[@PTranProductions]

No issue so far. There should not be any issue if it’s done this way or by following proper Toyota transmission fluid replacement procedure.

I did this on a 2012 sienna and only got 1 qt and 147 ml out. Plus l used a $7 manual bottle pump.

[@PTranProductions]

Did you remove the plastic straw inside the drain plug?

[@Chalkida24]

What if we weight the fluid we took out and we put the same amount. It is more accurate.

[@PTranProductions]

Doing by weight may not be a good idea and accurate because the old fluid may contain contaminations. Therefore old dirty fluid may be heavier than new and clean fluid.

[@Chalkida24]

@@PTranProductions Even if that happens the weight is going to be not even grams from contamination. And the contamination is going to add some volume on the fluid as well. 🙂

[@PTranProductions]

@@Chalkida24 You got your point there, buddy! I guess whatever way easier for you. It’s your choice.

How would you check if the level is correct?

[@PTranProductions]

There’s a special procedure outlined in the Toyota repair manual for checking transmission fluid level on sealed transmission which is not practical for DIY. This involves vehicle to be level (ideally on a hoist), Toyota computer program (Techstream) and transmission fluid to be between 40 - 45 °C. So as long as no leakage on the transmission, filling back what comes out is a quick and easy way.

I have my 1st service to be done on my wife’s 2021 Subaru Forester and it requires transmission fluid to be ‘checked.’ I think I’m going to be ripped off big time $$$.

[@PTranProductions]

Transmission fluid check on a 2021 model? That’s strange! However checking the level to insure it’s correctly filled from the factory would not be a bad idea. Hopefully they won’t rip you off. I have never done any level check for my van for the last 9 years and it’s not even in the Toyota service recommendations.

your bucket mark could be vary big and left over in the bottle not cheked.

[@PTranProductions]

Bucket mark is approximation. Left over inside pump was compensated if you followed thru the whole video.
