Toyota 4Runner • FREE Maintenance Tech Tips - DIY Transmission Fluid (Drain & Fill) A750F Part 1

The Viking way is the easy way. Thanks for the video my dude! Definitely gave me confidence on pulling this off myself.

My only problem is i dont have a lift

Hey man! Awesome content as usual! On newer 4Runners, (21 4Runner SR5 here) can you show us how to place the truck in tranny Fluid level check mode doing the gear shift method from Park to Drive, then rapidly shifting between Neutral Drive , Neutral Drive Etc., until Drive light comes on solid, then back to Park and watching the Drive light behavior while vehicle is in Park. My question is a jumper cable is needed to be inserted in the OBD2 port pins 4 and 13, but my truck doesn’t look to have a 13 pin ? Am I still able to use this method for Fluid Tranny Check mode on 21 4Runner SR5? Thank you!

Huge thumbs up. Thank you sir

Once the trans reaches the proper temp, do you drain the excess fluid while the trans is in Park or Neutral?

Recently I noticed om my own 4 runner when idling I could hear the buzzing sound coming from the transmission pan, bell housing area and I was freaking out thinking I had a torque converter or pump going out. I noticed I can hear the same in this video. Is this a normal sound?

Hey man, first off great videos.

I want to do a flush. If I get the gun to check the temperature, do I need to mess with the OBDII PORT? That part confuses me.

My plan:

1. drive the vehicle. level the vehicle, drain transmission fluid.

2. Measure how much oil came out in a jug. Re add that much and a smidge more.

3. Start the car, run it through the gears. Go and check the temp with the gun.

4. Once it reaches 104-113, undo the check bolt till it dribbles out.

Does that work? Thanks

I'm not sure if I caught that but how many times should I do it the drain in the field before it's all new fluid every 5,000 mi 3,000 miles Just wondering my car has $110,000 miles on it I already had somebody drop the pan and changed the fluid not a flush, but how many times should I do it

The only problem with this method is you are relying on guessing it had the right amount in the first place. In fact, there are Toyota owners on forums who even report that the factory underfills some of the transmissions. So even the very first fluid change may be a guessing game.

Great tutorial! Would you recommend flushing the transmission fluid from coolant line by turning the car on and refilling? I have seen other videos when they do it that way they change fluid completely and refill. When I drained fluid, dropped the pan and refilled, then only about 3 qts came. But the entire capacity is about 7 qts.

Thank you Viking.

So if only 1 quart comes out, you would put 1 quart back in? Not a good method for a technician that works in a shop...

You don’t cycle the transmission between the gears to get the fluid through them? How come? Do you check the level with YOUR method? Or just fill and go?

@VikingsGarage What A/T Oil Temperature reading in Techstream do you refer to when adjusting the level? There are 2 under Data List and they are off by a few degrees. Please let me know. Doing this service tonight ​​⁠

Great stuff! I bought an '05 V8 4Runner with the A750F. The CarFax showed regular "scheduled service performed" but did not specifically indicate if any transmission fluid service had been done. I'm religious with oil changes and have changed diff and tx case oil but have been afraid to touch the transmission fluid. I'm going to do the drain/measure/fill every other oil change 3 or 4 times then every 30k after that. You mentioned to another high mileage viewer adding "Lucas Transmission Additive". Is this the "Lucas Transmission Fluid Conditioner" or the "Lucas Transmission Fix" product? Also I assume I add a quart of the Lucas in place of one of the replacement OEM fluid quarts?

I appreciate videos like this because I accidentally dumped maybe a half quart (maybe 1) of ATF the other day doing my first oil change. Dealership wants to do a complete flush at 15k. I just want to do a top-off. This video helps!

I Have a 2007 fj cruiser, what size socket do i need to remove the fill plug (transmission)

Thanks for the instruction. Do you notice any big variance between a thermal gun reading and the scan tool reading? The Car Care Nut mentions to avoid using a thermal gun but it'll be interesting to hear your take to make the job easier for home DIY.

Not sure if you cover this in the video, but do you bring the transmission up to running temp before draining the fluid? Or do you drain the trans fluid in cold temp?

step by step. This awesome guy always takes the time to show you how to do it CORRECTLY

How many kms for a transmission drain and fill on a 2021 toyota 4runner??

My 2016 Limited has 123k miles and has never had the transmission flushed, what is your recommendation? Some say to not, others say still ok. Please HELP!!!

I like the channel and the tips. Great content VG….. cheers from Alberta Canada.

This is the worst fucking how to i have ever seen, what tools, what sizes, why did you have the car running while younwere draining the fluid? Do you leave it on?

Do you know the Torque spec on drain plug?

whats the correct answer ?
A750F full oil capactity 11,1l - you change only 3... what about the rest ?

You're my go to for info on my 4runner. So i dont need to do temp if i do it the viking way? Just a simple drain and fill with the same amount? Thanks again man! Aloha from hawaii.

The vehicle was hot and running when you drained for correct level, correct?

My local Toyota dealer tells me "we don't recommend draining the transmission fluid as it is a sealed system" and then tells me "but we can do it for $300." my question to you is, with the Viking method of draining and refilling, does the transmission need to be up to temp before driving off or can I just put in gear and go? Also, do I have to change the filter? (I'm aware there is a filter change video.. currently watching. Just wanna know if just doing a drain and refill will hurt anything is all...I don't trust myself with dropping the pan) I just bought this 4runner with 62k on the clock... She's all I got and I don't want to potentially damage anything because I may have skipped a step. I wanna do preventative maintenance such as this to keep it going as long as possible. Thanks in advance!!

I measure the amount of transmission fluid that comes out of the pan and that is the amount that goes back into it, keep it simple

Needs a dipstick🤨

I did it! It took about 2 hours including jacking the whole truck up so it would be level and taking my time. Just under 3 quarts. I have 28k on my new to me 4R. I use it off road a lot so I’m going to do this twice a year. Thanks again!

Do you have the part number to the Toyota adapter?

My dealer is giving me grief over the idea of wanting to change the fluid. I haul a camper around for half the year. I also have an aftermarket transmission cooler. The way they were talking it was as if I poured sand in my engine block. I appreciate your videos

Thank you so much for these maintenance videos! I recently sold my 4Runner, but, by sheer luck I found my dream vehicle: A beautiful 2013 FJ Cruiser in Army Green with 85k miles. Hoping to do a lot of this type of maintenance myself and hope to keep it for a long time. This video has helped boost my confidence immensely!

I just drained my transmission fluid on my 5th gen 2021 4runner, I had about 3 1/4 quarts come into my bin. What do I do? Fill it up to the amount or am I okay with just filling up with 3 qts of TOYOTA ATF?

I found out thebest way to refill is w a pressure sprayer about 10 bucks at most stores

Do you know if the temp for the check is the pan temp or convertor? I got a obd reader and app, and im assuming its the pan temp, but does the manual specify?

You sir, are a blessing to me and my 4Runner. Thank you so much.

Thanks Big Guy. I can change my own oil and now I feel like I can do this too. I have a 2019 4R and I want to keep it for 10 years or more. I have just over 25k on it and some off-road miles so I’m changing my transmission fluid.

I’ve done it many times never a problem

Thanks for saying that "you dont need more than 3 quarts".

So 2004 tundra with dip stick under hood. That's where you refill, right

Is that dipstick straw removable

Dawg smooth almost kriminal

How often do you change the other fluids? Diff, coolant, brake, etc...

Hey where is your shop located, i see jersey plates.

Thanks for the video. My only question is what about changing the filter? You didn't mention it.
