Nice video, but last time I changed my transmission fluid, my transmission started slipping. And after going through months of transmission hardship, it eventually lost drive and reverse. Don't know what happened, but changing the fluid did more harm than good from my experience, and I won't do it again now that it has the Aristo GTE engine along with the 4 speed auto in it. Next time, I'll fully rebuild the transmission.
From what you described, I’m going to guess that your transmission had a lot of miles on it, and the clutch packs had worn out and clogged the passages. This is actually not apparent as the transmission will still function normally, but when the new transmission fluid comes in, the fluid removes this debris/gunk from the passages and causes slipping. That is why it is said that changing the fluid will not cause any problems that are not already present. Your new engine/tranny combo sounds great, if the fluid looks really dark/burnt I would leave as is. If it looks red/pinkish, then you could change out the fluid, but without knowing exactly how often the fluid was changed, this may be a gamble. All the best, and thanks for watching! :)
I wonder how many miles you had on the car, and what color/condition your old fluid was in... I have around 165k miles and the transmission fluid in my car seems to be original (1998 Gs300) I'm on the fence about doing this service on the car. Currently the car has no issues going into gear, and changing gears while driving. Very smooth and has no stutter. I have been told its at my own risk.... what do you guys think? Should I change it based on the above? I've had the car since 40k miles (2012) but was told against doing it all that time ago because its "lifetime fluid" i see now that that's very dumb, and I should have gone through with the drain and fill then.
@The Lexus Chap Exactly, I was warned. I took the gamble and lost. I drained and replaced the filter at 170k miles, and the fluid was dark and smelled burnt. Engine and transmission swap was done at 225k once the trans went out. The transmission was shifting buttery smooth before I decided to do anything to it. Feels really good to finally be driving smooth again, but I'm afraid to drain the fluid, so I'm not touching it when that time comes. It's all good though.
@Cameron It was exactly at that mileage I wanted to do a drain and refill with a filter change. I was warned not to do it. Then decided to pull the trigger at 170k miles. Fluid was dark and smelled burnt, but transmission also had no problems, still drove super smooth, shifts great. But you had yours since 40k, and you never done a drain and refill. I'd say don't do it. Drain and refill your differential instead.
Changing transmission fluid is so easy to replace on older cars , the ones with cvt are a pain in the ass , take out the air box , take the wheel off , make sure it’s on a level surface , install a jumper wire to get it to the proper temp , take off the skid plate , remove the plastic straw etc….
Definitely true, another category I find rather interesting are sealed transmissions where there is no dipstick and thus no way to even check the condition of transmission fluid. Definitely useful to be able to monitor fluid as transmission repairs can be so expensive! Thanks for watching! :)
Here's my experience: First time I didn't have ramps or a good place to jack up the car, so I got my suction pump and sucked out about 1 quart via the dipstick. Expected more but no big deal, put a quart of T4 in, drove around for a week no big deal. Week later I acquire the plastic ramps from Harbor Freight. Drained the pan after driving a half hour and only got 1.5 quarts out, replaced. Expected to get more out this way. Am I missing something here? Levels look ok on dipstick.
Excellent video, very through and I love the chapters. I'm considering changing my fluid, it still looks decent, not new but not black. The transmission is starting to slip.170k miles. I'm worried I'll free up gunk and make the slipping worse if I do. You mentioned at around 1:05 that if the fluid needs to be completed flushed do it 2 to 3 times around 100 miles apart. Do you think that will help wash away the gunk or does it just get clogged?
Thank you for the kind words and I’m glad you found the video helpful! Unfortunately at that many miles on the transmission and it starting to slip, it’s impossible to say if a fluid change could help or hinder. Keep in mind that a fluid change (as long as it’s not a complete flush) will not cause issues that are not already present, only make them more apparent or fix them. So if your transmission is high mileage and slipping, changing the fluid is a gamble and could go either way. The safest thing to do would be to invest in a rebuilt transmission.
I know this was a few months ago but what does it mean when the transmission starts to slip? My 01 Lexus is having what I’m assuming is transmission problems when I start the car and give it a few minutes before driving off it doesn’t immediately go when I press the gas. It revs and continues when I press the gas until it finally goes fully into drive. It’s a pain especially when I also need to reverse within the first couple of minutes because I can’t.
@@jazmarie544 Hello! Unfortunately what you are describing does sound like a slipping transmission. One of the best ways to describe it is when you hit the gas pedal, the RPM goes up (the engine crankshaft is responding) but the transmission doesn’t do its bit and thus the vehicle does not move. That sounds quite similar to your situation. There are a few simple things you can do first before moving onto complicated stuff: 1. Check the fluid level (make sure to check only after the car has warmed up, as I describe at the end of my video). Low levels of fluid are not good for the transmission and can cause slipping. 2. After that, you can try and do a fluid change to see if it helps. I covered this in my previous reply on this thread, but at high mileages and when a transmission is already showing issues, changing the fluid is a gamble and may fix the problem or make it worse. You’ll have to decide if this gamble is worth it. 3. You can also try replacing the pan gasket and internal filter. This is similar to the previous point in that it may/may not help your transmission. I’m in the process of doing that on my transmission as part of my full reseal so once I’m done I’ll have a video for that also. If you take off the pan you’ll also get a chance to see how much metal there is in the fluid that the pan magnets pick up. That may give you some info on what is wrong with your transmission. All the best, and feel free to reach out if you have any more questions! Thanks for watching! :)
Hello! the 2nd gen. GS 300 does not really have a conventional 'filter', it's more of a mesh that traps particles. You shouldn't have to replace it at all unless there metal chunks floating around in your transmission fluid. Obviously at that point the transmission would most likely need a rebuild. But to answer your question, the transmission fluid filter does not really have a service interval. Hope that helps, and thank you for watching! :)
Hi Kelvin, that is interesting, here in the US we don’t have the Celsior but we have the LS 400 has a trans dipstick with a ‘hot’ region where the fluid is supposed to be at after the car has been warmed up. I’m not sure as to why your dipstick does not. As for the fluid capacity, the owner’s manual specifies 2.0 quarts of Toyota Type T-IV fluid for a drain and fill for a 1998 LS 400. To be most accurate, I would suggest measuring how much you drain, and then putting that much back in.
No I did not reuse the old fluid, I added new fluid. I show the old fluid in the bucket so that you get an idea of how much fluid to add. Thanks for watching!
I️ just changed my fluid, and I️ think I️ might be anxious over nothing. But is it normal to have the car jerk when switching into low gear while moving (at low speeds)?
Hello, What kind of speeds is this happening at? And since you just changed the fluid, it’s important to make sure the fluid level is spot on. Remember to get the car up to full operating temperature before you check. Low levels of ATF can definitely cause jerks.
@@theautochap I’m dumb, I️ didn’t realize that it’s normal for a jolt when switching to low at speeds higher than 10 mph. I️ should have known as I️ only owned manual cars before this lol
@@whatsacommentary totally understandable! As you said, a small jerk is normal while shifting into low at higher speeds, which is why I asked what speeds it is happening at. The A650e transmission is a very rugged transmission and as long as fluid levels are good, you shouldn’t have to worry too much :)
@@whatsacommentary Yep! As long as the fluid is anywhere between the two notches in the ‘hot’ area that is fine. Of course the closer to the second (higher) notch the better, as that will leave some margin of error if you ever have a fluid leak or something.
Clear understandable video and straight to the point.💯👍
Glad you enjoyed the video and thanks for watching! :)
Thank you for all your videos on the GS.. just got one and your helping me out alot

How many liters should I fill on Toyota Celsior UCF 20 (1998)? At least how many liters should be inside? There's no Hot or Cold area on the dipstick.

No change filtre transmisión???? Wats
Hello! It is not required to change the filter as it is just a screen.
Why not change the filter?
It’s not necessary to change the filter.
good job but you didn't replace the filter it's important
nah don't need to
Forgot the gs400
You are correct this video also applies to the GS 400. Thanks for pointing it out and for watching! :)
