How to Service a Sealed Toyota Transmission

How to Service a Sealed Toyota Transmission

​In this video, I perform a very simple version of a Toyota/Lexus transmission fluid exchange service, for cars with sealed (aka no dipstick!) automatic transmissions. I do my best to explain the procedure in a really generic way so it may apply to many more Toyota vehicles.

🔧

The cars used in this video are:
a 2006 Lexus LX470 with the 4.7L, V8 engine paired with the A750F Automatic Transmission (which is also found in the 4Runner, Land Cruiser, and GX 470)
and
a 2009 Toyota Tacoma PreRunner with the 4.0, V6 1GR engine and the 2WD version of transmission in the Lexus (lending it a different name, the A750E).

🔧

In case you are wondering why I did not show how to put the vehicle into transmission temp check mode: there are two reasons. The first is that the temperature check procedure does not apply to all vehicles. For example, this Tacoma does not have that option. The second reason, is that I tried to explain the concept of check mode, without being able to show it, and the video got long and wordy. There are other great videos out there that can explain this, I am sure, and if not, you bet I’ll be making one when the opportunity arises and upload it here on YouTube.

🔧

Service notes:
– Make sure that you have test-driven the vehicle prior to servicing (you want to perform this drain and fill procedure on a cold transmission) and if the test drive and service are within the same day, that you give yourself plenty of time to let the fluid cool back down. I hope you sold the customer a few more jobs! 🙂

– The vehicle MUST be on a level surface to perform this service, so verify that first.

-OR-
Here is a basic Performance Tool hand pump that can be found at your average auto parts store: https://www.amazon.com/dp/B00J8331U6/ref=cm_sw_em_r_mt_dp_U_V.AXCbCKNJS6D if this is a tool that you will only use once every 60k miles.

Here is the Infared Thermometer I used in this video: https://www.amazon.com/OEMTOOLS-25245-Infrared-Thermometer/dp/B0014WIT6K (bought it at AutoZone, I think…)

Parts used in this video:

Toyota WS Automatic Transmission Fluid, 6 Pack: https://www.amazon.com/dp/B07BZ2HZ6W/ref=cm_sw_em_r_mt_dp_U_0GBXCbB40ZF5N (I just get mine from my dealer, its actually a better price than anything you will find online)

Drain plug crush washer: 35178-30010 (I always ask the dealer to thrown in the gaskets for free when I buy the fluid, just like they do with the oil drain plug gasket when you buy the oil filter…. or is your local dealer not that cool? If not, a 10 pack can be found here online: https://www.amazon.com/Transmission-Gasket-4Runner-Replacement-35178-30010/dp/B07JQFH5V2 and though you probably don’t need this many, it seems to be the best deal!) Note: the overflow tub/check port uses the same gasket and has the same torque specification.

Fill Plug O-Ring: I actually get this out of a generic kit rather than buying from Toyota (WHOA, I KNOW!) but just be sure that the O-ring is intended for use with transmission fluid!

🔧

Torque Specifications:
Drain plug: 15 ft lbs
Check Plug: 15 ft lbs
Fill Plug: 29 ft lbs

Temperature Specifications:

36 to 46°C (97 to 115°F)

A giggly mechanic -:) A Welcome change! There is something REALLY SEXY about female mechanics… -:)

Quick question- does anyone use an inert gas like argon to purge the air out after the fluid change? Does the factory purge out the air? Specifically for the non dipstick cars

Aung Zoo says:

What you think of Amsoil ?

I seek you council, ol'wise one. Can I get your advice on what you would do in a situation where your looking at a scion xB with 165k miles and has never had a transmission fluids change, ever? What do you recommend? To get this car back into optimal shape. The reason i ask, is becuase another professional said to leave alone. Becuase there is a possibility that the valve body in the transmission is clogged due to the fluid being very dirty and low, that the transmission could fall down a downward spiral and could slip after the doing the change. What would you advice me to do? Any advice would greatly be appreciated. Thanks in advance.

Did the label on these oil bottles change because the ones I got from Amazon look way different

Michael Decker says:

What a thorough,articulate,well explained and easy follow video. I love your patience of explaining the basic knowledge of things (like the reading of the tags under the hood showing which transmission type),and why the multiple flushes. Also THANK YOU for using a tripod or extremely steady hand work on your shots. Others seem to talk with their hands including the one with a camera in it and one ends up feeling nauseated from the shoddy camera work. Great editing as well, lighting, and suttle,but, not overpowering background music. All others should take note and follow your standards.

bob cole says:

Isn't there a tube up in the drain plug to maintain proper level that needs to come out too?

LANA GOONIE MOON WALKER says:
