As you can see in the video this job did not come without it’s difficulties. If I were to do it again I would have just changed the fluid and left the filter alone and things would have gone a lot smoother I think. I’m going to wait and see what happens with the MaxLife trans fluid, so far I haven’t heard anything about any problems with it and it’s been a couple of months since I shot this video. So if you need to perform this service the service interval is unclear but I would consider it around 60K and at that time I would just do the fluid and leave the filter alone.

  1. Adding exactly what you put in will work if the original level was accurate in the beginning. If you have a transmission fluid leak then check the fluid according to the manual at the end with a scan gauge. These transmissions need to be checked at a certain temp.

  2. I don't imagine Eric reads these comments anymore… But anyway I just got a 2008 T4R with 215,000 miles. Silly me getting such a high mileage car. "They run forever" is only 50% true. Before even putting 20 miles on it I've put in a new radiator, new serpentine belt system, new exhaust, new front CV axles, changed diff fluids, and new spark plugs. Couldn't believe this – but the spark plugs were factory OEM. 215,000 miles and 12 years on these plugs. I know they were factory because the driver side was NGK and the passenger side was Denso – only the factory does this. Plus the gap was big enough to practically stick your finger in. Surprised it still ran.

    Anyway, if the previous owner never changed the plugs, surely they never touched the transmission, right? But isn't it risky to do a fluid change on a high mileage vehicle that's never had one? Eric changed all the fluid out here, and that fluid likely could have been factory fluid. Not sure if I should take the gamble to change the fluid/filter, but I'm not sure if it'll make it to 300,000 and that's where I intend to take this vehicle. No shifting problems now, smooth tranny in every way, just not sure how long that will last. Any advice, super high mileage DIYers?

  3. I believe putting back what you took out isn’t the best way to do the service. What if it was low to start? Find out the correct amount for service and apply Accordingly.

  4. I have a 2011 four runner with 135 k on it and for the last week I'm having a some studdering. Looks like the converter and my transmission man suggested changing fluid over to the DW1 Honda fluid and that it should take care of the issue. What are your thoughts on this my friend. Thanks

  5. Sorry man, I laughed when that exhaust bolt twisted off. I always expect exhaust bolts to twist off when I crank on one, and I know that sweet, sweet emotion that floods one's heart when its the last bolt that has to be tightened and that's the one which snaps 🙂

  6. Dude. Re using old crusty Toyota truck hardware is a bad idea. Also might want to plate weld that weak frame spot where the exhaust hanger is bolted to it. That’s a crack or a crack happening soon.

  7. Hi Eric,
    First of all i really appreciate that you share all that knowledge,love your videos. So i have Toyota 4 runner V8 2005. I recently took it to a transmission specialist to get the fluid replaced and after it was done my transmission start acting out and upon acceleration won't move various times and then again will start moving while i am on the road driving, any tips will be appreciated?

  8. Hey Eric,

    I’m doing this on the same model. I have the pump. I couldn’t see in the video where you filled the new fluid in. Is it above the pan?

  9. Does not make any sense, change 3 qts over 11 and half qts, I do not see the benefits, my 2006 Toyota 4Runner has 170K with the original fluis on it and the transmission it is smooth like a baby, thanks anyways for the video.

  10. Use level check port in bottom of pan (6mm hex drive) to fill this trans. Not the side of trans plug. Adapter is available or just use a plastic 1/8NPT 3/8" barb fitting to screw into port. A pump like this works good https://www.amazon.com/Advanced-Tool-Design-Model-ATD-5024/dp/B000OUW7CK/ref=sr_1_15?keywords=5+gal+pump&qid=1560309520&s=gateway&sr=8-15

    Connect pump hose tip to adapter barb in level check port with 3/8" ID hose. To begin with, fill trans based on how much you drained out. If you're pumping/purging old fluid out through trans cooler lines, pump another qt into trans before starting vehicle. Use a 5 gal bucket with 1 gal increment markings on the side so you know how much to pump in when purging old fluid. Shut off vehicle when purged fluid looks reasonable. Reconnect cooler hose and start engine to check level. Remove the pump hose from adapter in level check port to see if any fluids comes out when up to to level check temp. If not, add 8oz at a time.

  11. Excellent video! Thanks for building my courage to do this to mine. (2003 Lexus GX470, same engine(2uz-fe)/trans(A750F), 135k miles, recently acquired, poorly maintained by previous owner). My blessing is that mine has a trans dip stick, which I believe went away in 2004. 😎

    Side note- on my recently sold 2007 Camry that I acquired with 72k miles, the Maxlife trans fluid does great. I had all the trans fluid replaced at 72k miles (by a former Toyota mechanic) and sold the car with 144k miles (72k miles put on the Maxlife fluid). Never had any trans issues, and shifted like new.

    My big question: With there being ~12qts in the whole A750F transmission, after dropping the pan and replacing the ~4qts that comes out, would it be recommended to drain/fill ~3qts a few times to try to get as much new fluid in there? If so, after how long/how many miles?

    My GX470 rides and shifts like a dream, no trans issues, but I'm going through everything to so that I can be confident with its reliability as my daily driver. Thanks!

  12. Thanks Eric
    I love your video. Although I did run into a issue with my 4runner. I accidentally drained the transmission fluid thinking it was the motor fluid and was not aware at the moment so I drove it for 2 miles without fluid unit I found out it was the wrong fluid since she started shifting hard. Finally filled her back up and now when I brake hard the transmission feels like it slips. Do you think a complete transmission flush will work? Currently has 205k miles. Any help is appreciated. Thanks

  13. I'm glad I've got a great Lexus-certified master technician that will do this. Its worth it. But when I was a young blood, I did all of this kind of stuff myself. Great video!
