How To Add ATF Fluid To Sealed Lexus/Toyota Transmission And Fluid Leveling Procedure 

Dude, all you had to do if you wanted to know if the fluid was low or not was run the engine up to the proper temperature, which is 95f to 110f°, remove the allen key check plug while it’s still running and see if anything comes out. If not install fluid “while it’s still running” until it starts running out that same hole where that allen bolt goes. When it’s only trickling out, put the plug back in and you’re done. If you’re having trans issues it would have been better to remove the pan and check for filings and what’s in the filter. Clean the pan and magnets, clean or replace the filter, reassemble with a new gasket, approx 5.5qts of new approved fluid. Run through all the gears, idle in park up to temp preferably using a scan tool for temp, remove that allen key bolt, wait until it’s only trickling and you’re done.

You're supposed to have the engine running

Thank you for taking the time to show us these things man, you’re a pillar for the F community.

This video save me a LOT of money! mine was whining and I did not know why and it came to a point that it would not move!. So watching this gave me the idea to fill it and sure enough rides like a charm

Keep going I'm learning so much from you. thanks

Heads up on the jump scare at @2:10 my man! lol thanks for the vid

Kinda surprised you're not using Toyota transmission oil. Seems like alot of Toyota and Honda owners usually are big on factory genuine part's and everything being genuine replacement stuff. Js beautiful car btw.

Thank you for the video & extremely cool that you can get a place with car lift to do the job. I would suggest the following to DIY's: 1. Get yourself a decent code reader...Autel or Foxwell to read live data ATF oil temp. 2. Draining level fluid when the temp is going up rather coming down is the proper way. Also, great choice to go with AMSOIL fuel-efficient ATF fluid, this is a superior choice and probably the reason why your tranny is no longer whining. I know there people here that will say use only Toyota ATF WS, I got 100K, 200K on my car without tranny issue and that may be the case, but AMSOIL has proven to deliver a smoother shift, better fuel economy. I've own 9 Toyota/Lexus different for the past 25+ years, all of them is still running even my 1987 Corolla with 465K miles. Keep the video coming!

Thanks a lot for your time ❤️‍🔥❤️‍🔥❤️‍🔥💯❤️‍🔥❤️‍🔥❤️‍🔥💙

appreciate this video bro

That check engine light that was on the dash, was it alerting you that the transmission fluid was low? Was always curious if our car would do that, I need be.

you just underfill your tranny. the engine must be running when checking the level. I just accidentally shut the engine off while doing this on my GSF and so much more came out and i had to redo the procedure. also it's way easier and accurate to pin the OBD and go through the gears rather that using the temperature gun. I will post a link on how to do it but I added the link to your previous video.

i think you’re supposed to leave the engine idling in park when removing excess fluid.

To adjust the level, the motor must be running. The oil temperature Must be at 95f - 108f

do you need a gasket for the overfill plug on Lexus Transmissions?

so just to make sure i understand. you add it until it runs out and then go let it drain until in trickles?

Made me flinch when the fill plug fell 😅

Is this the same procedure for rc350 awd?

You can use the paper clip trick with the obd port. It will tell you when it is in proper temp.

mines at 46k it kinda does it , should i just go head and drain and fill or just add some like this vidoe ? i beat on it .

Does this method work on a 2013 scion FRS?

I didn't think transmission would lose tranmission fluid??? why it would from first place?

Do you know where is a fill nut in gs450h 2013 model?

That was hilarious watching this guy who had no idea what he was doing try to fix his last mistake he made when he underfilled his transmission. I wonder how long he drove it like that because he probably did some damage driving it like that. If he ever needed to replace all his fluids before, now would have been the most important because I'm sure there is a lot more metal shavings in that fluid now that he drove it underfilled. And he just said screw it and tried adding way more fluid than he was supposed to, just wasting all that fluid only for him to drain it right out leaving most of the metal shavings clogging his filter and covering up all three magnets on the bottom of his pan. He never bothered to change any of the seals he just used the old ones again and he decided to say screw torquing any of the bolts he put back in. He needed a scan tool to find out the proper fluid temperature to begin draining the excess fluid and he just used a laser thermometer and checked the temperature of the outside of his transmission pan which isn't the same thing as checking the temperature of the fluid itself. And then he just went TADAAaa And that is how you do things the right way. LOL LOL LOL LOL LOL I couldn't imagine anyone would ever take this guy serious. It was total comedy and a lesson on what not to do to be perfectly honest. I'm sure the mechanics in that shop got a good laugh watching this banana work on his car. I'm sure that they will see him again when his transmission blows up on him and he needs them to replace it for him. I can't imagine why he would have still posted this video after what he did. Did he at least watch this video once before posting it? Does he really think that this video shows people the right way to do this job? Because I would be so embarrassed by a video like this that I would have to move far away to some cave to avoid having people laugh at me. And he is totally fine with it. WOW

Hello Barry, my RC 350 has about 114,000 miles, after checking service record there's no mention of ATF (only Synthetic Oil & Filter Luxury Service :) Was thinking about doing a drain and fill. Are you doing yours because you're the first owner?

WS for World Standard and you go and put Amsoil in it🙄 and engine gotta be running so you prob still ain’t got proper level in it, so this is not quite how to add atf is it?

I want to do the transmission service on my Lexus IS 200t. I don’t have a scan tool to measure temperature. Is it safe to measure how much fluid comes out with a 5 qt measuring container and then refilling exactly how much comes out with new WS fluid?

Good job ,Are located in New York ?

I got a 07 GS 350 I got a lil kick when I put it in gear could it be I'm low on ATF... ?

Hmmm my IS sounds like that when at higher speed. But doesn't sound like this at idle. Should at add more automatic transmission fluid in?

YOU SHOULD HAVE GOTTEN UNDER CAR LAY ON YOO BACK FEED THE LINE IN THE FILL PORT WITH A LONG HOSE WHILE SOMEONE POUR IN THE TRANSMISSION OIL WITH A FUNNEL AND THE HOSE FROM THE TOP OF THE ENGINE BAY THEM SHOULD HAVE CHECKED IT TWICE ON THE DIP STICK OR FILL DRAIN BOLT AFTER THE RADIATOR FANS KICKED ON AT LEAST 3 CYCLES TO MAKE SURE THE OIL WAS AT TEMPERATURE GOOD LUCK NEXT TIME

Isn't the same to fill through the allen plug???

Will it be the same process for a rc300 with a 8 speed?

I got a 2015 Rcf with 42k miles I heard that at 50k I need to do the same thing true or not?

So many things done wrong....Definitely not an official Toyota procedure. Only use Toyota WS Fluid!!! Suppose to use a scan tool for the proper transmission temp or use the paper clip method, cycle the gears and then drain.

Bro, Switch off the vehicle while draining the overflow oil🤔🤔

Good lord what a pain in the a**s. Never buy a lexus. You would think Toyota would have made them as easy to maintain as a Toyota camry.
