Been doing this for years on my 4Runner, GX, and LX. Tip: you don't need to refill from the transmission fill hole under the car. Disconnect transmission cooler outlet. Connect clear tubing from the transmission cooler outlet to a graduated bucket so you know how much comes out. Connect a separate clear tubing to the other end where the transmission cooler outlet is connected to go back to the transmission. This is where you refill the xmsn fluid using a hand/automatic pump. Start engine and let out 2 to 3 qt of old xmsn fluid into graduated bucket. Pump the same amount of new xmsn fluid back in. Repeat until all 14 to 16 qt of old xmsn fluid (black/dark red) is replaced with new fluid (vibrant red/magenta). The transmission filter and pan drop is not necessary until every 100k to 120k. Total time should take no longer than 1 hr. I have been doing this every 60k with either Toyota WS or Valvoline Maxlife ATF. Don't buy into the lifetime fluid speech from corporate. You'll destroy/damage your transmission if you don't change out the xmsn fluid.
Wow, thanks for that. I have no idea how it looks like inside the transmission from the trans cooler outlet end, so kind of worrying about damaging the transmission if I pump the fluid in from there without transmission running. Good to know that also works. The pan drop is just to replace all the pan bolts before any of the bolts get rusty and broken when I need to drop the pan. Living in the rust belt, and the transmission pan bolts have a really bad reputation of easily broken, definitely don't want that to happen to me. And agreed. I also don't believe any moving auto part could last forever, so changing the fluid regularly or has the transmission changed along with the fluid, that's an easy answer. Thanks for sharing these.
@@MoeGoe-xt3enI have a GX470 which shares the same sealed A750F 5 speed transmission as the 5th gen 4Runner. You do not if you take out the same amount as you fill back in, hence you buy a transparent graduated bucket from HomeDepot/Lowe's. There are plenty of A750F, AB60F transmission fluid exchange writeup on IH8MUD and other forums. The A750F and AB60F are known to run for a long time if you change out the fluids every 60k (do not buy into the lifetime fluid BS). The ones with transmission issues are typically ones that have neglected transmission fluid change intervals.
@@runnerxa Good to know. Thanks. Also do you think it's a bad idea Toyota used the same transmission in a 5th Gen 4runner V6 as they did in the GX V8? Or is it equally reliable handling that much power?
@@MoeGoe-xt3enWhat power? Neither the 1GR-FE V6 nor the 2UZ-FE V8 were known to be powerhouse engines. The GX470 and 4th gen V8 4Runner came out in 2003. That means the A750F (and the minor revisions) have been in used since 2003. The 5th gen 4Runner came out in 2010 using similar powertrain as the 2005+ 4th gen V6 4Runner minus the multi-mode 4WD/full time 4WD feature (that is only available in the 5th gen 4Runner Limited 4WD). The same A750F transmission is essentially in use from 2003 (2002 in Japan) to 2024... So they are pretty reliable but also pretty old tech, hence it gets the bad rep for fuel economy (15-18mpg). Powerwise, the A750F can handle a supercharged 4.7 V8 2UZ so it can definitely handle the 4.0 V6 dual VVT on the 5th gen 4Runner (even if the V6 is supercharged). Hell, even the old A340F in the 3rd gen 4Runner and 2003/2004 V6 4Runner can handle a supercharger.
Thanks for taking the time to make this super helpful video. I started the process on my '13 yesterday (was only planning on a quick drain and refill), and discovered the drain plug to be waaaay overtightened by the last person to do it (not me!!!) and stripped out. I'm glad you show how to drop and replace the pan, because I've got a replacement on order.
@@felixsun548 got it all done this morning. Thanks to you, everything went smooth! I do wonder if I was a little under filled. I added back what I removed, plus some for spillage, but came up short and had to add more. Glad to know it’s all done correctly now! There’s not a ton of diy information on these sealed transmissions, so thanks again for taking the time to make this video.
Nice and clear video, and you included a lot of small details. I used this same approach for the fluid exchange (prior to seeing your video) and it worked perfect.
Great video, and thanks. I’ve noticed refill valve looks a tad diff in earlier 460 than later models. I drive a ton for work, so doing a drain/fill on my ‘23 later today.
Fantastic job. Dealers where I am wouldn't even think about flushing out the fluid in the cooler, takes too much time for them and they don't care lol.
Actually, if you have the right tools, it should be easy and quick. But it's true that flushing the cooler adds complexity and the extra time that costs might not make the same money for the mechanic in the dealer, so why should they do this.
Great video and THANK YOU! Just did it on my 2011 GX and all went well. No oil come out when it was time to pull out the overflow plug to check the level. Put more in and then it come out..
Why did you hane a second tube line comming from the oil cooler thermostat going to the 1 gallon jug? Looked like that line should have gone back to the transmission and woul have saved you some fluid.
yup, I never thought the oil would come out from there, so did not prepare a plug or something to block that hole. I simply put a tube to catch the oil from there so I don't need to swim in the leaked oil.
Yeah, I was wondering I was wanting to do all my own work on my truck because the dealership jacks are on the price. My problem is is that I don’t know how to jack up the car properly. What do you use to check the car up if you don’t have a lift like the mechanics too.
I use four 'Rhinoramp', which would give me about 9 inches raise. There will be plenty of room for most of the maintenance. Only issue is, you cannot do any service that requires taking off the wheel. The trick is to use 4L drive mode, it made it easy to climb up the ramps.
No doubt. For non-critical part, as long as I could find cheaper OEM one on RockAuto, I would also go with it. But for some critical parts and those not require frequently replaced, I would go after the dealer.@@MoeGoe-xt3en
the service book suggested to do so to prevent accidentally adjusting the suspension while the wheels are lifted off the ground. Of cause, if the GX comes with no adjustable air suspension, or the wheels are on the ground, no need to worry about it.
I'm not sure about that, all the numbers in my video are from GX460 repair manual book. If you are not sure which number to trust for fluid level check, check my another video which shows you how to do this without monitoring the accurate temperature by using the built-in function. This function won't lie to you and is your GX specific. ua-cam.com/video/kFdTAW_on_s/v-deo.html
I did not take out the whole pan, and just remove the drain plug, as ur video show, to see how much fluid I need to refill back, just keep the overflow drain plug open until the fluid come out, does this work?
keep the overflow drain plug open, refilling ATF until the fluid come out from the overflow drain is only to ensure you put sufficient fluid back in the pan. You will still need to process the fluid level check under certain temperature, otherwise, your transmission could malfunction.
I drained the Transmission oil on my 2015 GX460 without collecting the used oil. Since I have no way to measure any more, can you tell me how many quarts to add after draining from the drain plug (not the overflow pulg)?
Put the drain plug back and remove overflow plug and leave it open. add oil until oil come from overflow hole, put the overflow plug back on and start oil level adjustment. If you just want to refill without perform the level adjustment, it's a bad idea because there is no way to tell how much oil you drained. The service book states a "drain and refill" requires 3.2 US qts, but the number would definitely be different from the amount you drained. Oil level adjustment is recommended, otherwise you are on your own risk.
😂don't have budget for just a fancy tranny cooler yet. Unless you need to tow a heavy trailer or overloaded your GX and run up tons of hills, there is no need for a bigger separate tranny cooler. But in case you need, check this: ua-cam.com/video/7T5mmJJYkDU/v-deo.html
Service book states 3.0 liters (3.2 US qts) for "Drain and refill", and 11.1 liters (11.7 US qts) for "Dry fill". The oil is cheap and returnable if not opened, so I prepared 12 US qts for the entire flushing procedure. Not sure how much it's needed for a simple "drain and refill". I'd suggest to prepare more and return unopened bottles later.
I use this tool: www.amazon.com/gp/product/B098LF38DS/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 It's quite pricy, but overall it's a pretty powerful tool at this price and comes with a good number of additional functions to customize the car. For example, it allows you to program new keys which I haven't gotten chance to try (hopefully I never need to use this feature). I don't sell tool, but I'd say a good tool is a good investment if you work on your car(s) from time to time. Otherwise, there are other options cost less than $100 if you just need to monitor the fluid temperature. I also posted a link to show how to check the temperature without a tool.
Well, some Lexus dealer websites recommend to do it every 30k (for the money in your pocket), but the maintenance book and most Toyota/Lexus forums suggest 60k or 6 years. So unless you know you had done some seriously heavy push on your transmission or it has been 6 years since you bought the gx, leave it as is. IMO, changing/flushing the transmission fluid is just to prevent changing the transmission along with the fluid, but not to keep the fluid always looking good. Plus the complicated procedures adding risk in damaging your tranny if not done right.
Sorry buddy, I'm not a mechanic. Your 4r has way more mileage than the recommended change interval that I've heard. The 2015 4r should also have the transmission oil pump which would create high pressure, and it is said the tranny may fail after a flush for a high mileage tranny with a pump if it has never had the fluid changed before. So do some research before you start, maybe a regular “draining and filling" is better for your case, but there is a topic which might help: canadiangearhead.com/transmission-fluid
Btw, I noticed this video which might address some of your concerns about flushing the tranny, check it out and good luck ua-cam.com/video/gx5dU3UVcRs/v-deo.html
I cannot tell you an accurate number because I didn't measure, but the repair manual does say that it requires 1.8 qts for draining the pan, and 4.5 qts for removing the valve body. In practice, I used in total 12 qts to do the entire flush until all oil turned fresh red. There were 3 drain-and-refill for the transmission oil cooler flush, 2 qts for each refill so that's 6 qts, and 1 addition quart at the end to make sure there was enough oil before level check. So I would say, 5-6 qts to be safe if you replace the oil filter, and at least 3 qts for a simple drain and refill oil replacement. The transmission fluid only costs $9.2/qt from a Toyota dealer, so it won't cost much to be well prepared. Good luck.
@@felixsun548I just changed my transmission fluid using this video. Very clear and made it a no brainer on my end. Thank you again!! I made myself a pressurized fluid dispenser with a normal 1.25 Gallon garden sprayer. I cut the spray nozzle off, heated the plastic tube and used a screwdriver to form an "L" shape. Went one step further and drilled a hole and installed a normal tire valve so I could just pressurize the tank. I opted to do 3x drain and fills instead of a full fluid exchange because my GX has over 100k miles on it and I am wary of a full fluid flush
@@reddyuda You are a genius. I've never thought about turning a garden sprayer into a fluid pump. I don't enjoy pumping the oil under the car but I also don't want to throw $70 for a pump on Amazon. I'd better to make one for myself LOL Multiple drain and fills would work, it just costs more time and crush washers to do so. But still, checkout this video and think about if his opinion on the different way to flush could make your next change/flush easier. ua-cam.com/video/gx5dU3UVcRs/v-deo.html

Rockauto is cheapest and they get quality OEM or near OEM parts.

I've put all the retorque spec at the beginning of the video and as well as anytime a bolt/plug needs to be retorqued. Be aware of the subtitles.
May I ask what is the purpose of pushing the thermostat?
the service book suggested to do so to prevent accidentally adjusting the suspension while the wheels are lifted off the ground. Of cause, if the GX comes with no adjustable air suspension, or the wheels are on the ground, no need to worry about it.
Why some place says the Normal temperature for transmission is 160 to 220, but yours is 115 to 126, is there any different?
