How to change your Toyota Sealed Transmission Fluid

A Toyota master diagnostic technician explains step by step how to change your toyota sealed transmission CVT transmission and new 8 speed transmission!

Please read the notes in the description that's applicable to your Toyota transmission. Leave a comment or email if you have any questions.

In this video I will go over how the sealed transmission works, Also how to drain the fluid and add new toyota transmission fluid. Also I will go over the 3 ways to adjust the toyota sealed transmission fluid level.

This applies to all Toyota models without a dipstick. If you own a 2014 2015 2016 2017 2018 2019 2020 corolla with a CVT transmission it's the same procedure just make sure you use the correct genuine Toyota CVT FE fluid.

This also applies to Toyota's new 8 speed transmission in many models including 2017-2020 highlander 2017-2020 Sienna 2018-2020 Camry 2019-2020 Rav4 and more.

Notes on 8 speed transmission:

- The drain plug that I showed in the picture in the video is gonna be a 10mm hex and the overflow tube will still be a 6mm hex socket.
-The cooler bypass will be located between the transmission and the radiator, you have to remove the front driver's side splash sheild to access it (10mm screws and clips) Also this only applies to some 2017-2020 highlander and 2017-2020 sienna models. If your highlander or sienna doesn't have it then skip the cooler bypass part.

Notes on some tundra and sequioa models.
-Some of these models will have 2 drains on the transmission pan. one is going to be a drain plug and the other will be the overflow tube. so drain the one then tighten it then use the other plug to adjust the fluid.
-The cooler bypass will be available on some of them located by the transmission on the passenger side.
-The fill plug will be located on the driver's side of the transmission also a 24mm bolt.

Notes on some Tacoma models.
- Some Tacoma models will use the A\T OIL TEMP light instead of the D or Drive light.

This procedure does NOT work on the following models:
2020-2021 Supra. Any toyota with a dipstick. All scion IA and Yaris IA and the new yaris hatchback. Scion FRS and Toyota 86. All hybrid models.

Tools needed:
-10mm socket for panel removal.
-21mm socket for wheel removal.
-6mm HEX socket.
-10mm HEX socket (only for 8 speed transmission)
-drain pan
-a container with quart measurments
-a fluid pump( one used in the video linked below)
-Small jumper wire.
-Temp gun if using this method (linked below)
- 4 jack stands and jack if lifting the car off the ground.

Parts needed
-For CVT transmissions use Genuine CVT FE transmission fluid. It's sold in a 4L container.
-For WS transmissions use genuine WS fluid. They are sold in 1 quart bottles.
-2 washers (or 3) for the drain and fill plugs.

Aftermarket fluids :
I do not endorse nor recommend the use of any aftermarket transmission fluid in any Toyota WS and especially CVT transmissions. If you choose to use a non original fluid you are doing so at your own risk! Always shop around for best deals and prices from the dealership or online for original parts.
