#Lexus es 350 2007 throttle lag

How often are you flooring it? I think we discovered a contributing factor to your fuel consumption! But that’s not related to the question.
You’re in drive, you hit the gas pedal, rpms climb, car goes nowhere, correct? Do you then hit it again and the car starts moving?
Yes I reset my tcm
I then discovers my car makes a whine when I gas hard is that normal
Also after reeetting the electronics my brake pedal is hard when my car is off it’s not soft anymore it’s soft after the engine starts it that normal ?
I feel like there is always something new with this particular cars threads lol
Thats normal. In short the brake system is off when the car turns off. When the car is turned on it will function as usual. It’s just the properties of an hydraulic break and the brake booster getting turned off
Regarding flooring it and going no where, maybe it’s just the characteristics of the ES since it’s a economy car it isn’t geared toward fast shifts like the F line Lexus has
It drive good still I rested the car but sometimes at 40mp when I full throttle it doesn’t go anywhere and rpms go up people telling me my trans ficked but how can I tell for sure
That’s genuinely my concern as well - as described, this sounds like a slipping transmission. The thing to do next is have a conversation with 1-2 local independent transmission shops.
I’m going to do my own trans flush
Smart or no ?
Any other test I can do to make sure. I mean what if I’m in between gears at 40mph and that’s why it stutters for a few seconds when j gas it
Maybe it will fix the occasional slippage? If it’s it bad that is it’s at 77k so I think it needs changing ?
It’s worth a shot. I’d suggest doing a pan drop, replace the fluid and filter, but not a flush. Doing just a pan drop doesn’t replace all the fluid, but it is safer for something like this: by doing a flush, there’s a risk of dislodging built up gunk inside the trans that can find its way into more delicate parts of the trans and make matters worse.
so i dont do flush? im confused
woujldnt it be a good thing to get tht gunk out
Don’t flush, just drain and refill
I forget if that transmission has a drain plug or if you drop the pan
whts the dif from draining the old fluid vs flushing it out
If you flush it, gunk that gets dislodged may get stuck somewhere important where it can cause real issues.
im puzzled now. my autos teacher at school told me we gonna flush it tmr unless he ment drain idk
So there are mixed opinions out there on flush vs drain. I’m partial to avoiding risk, maybe a little too cautious, but your auto teacher has likely had good success with doing flushes. There’s no right answer, I’m just risk averse.
hes not a mechanic but hes been teaching automotive for 20+ i think more and has went to auto school. idk if i should trust his info
do i trust him. even tho hes not a mechanic
You’ll be good listening to him. 20 years is a long time. I’m not a mechanic either, just an enthusiast who enjoys working on cars.
lol ok ty for ur help
also while im at it do i flush coolant? and how much coolant do i need i just padi 30 usd at toyota for a 50/50 coolant about a gallon
Yes, and your car probably takes 2 gallons or more…. Lemme see if I can find a capacity
Yep, 7.9 quarts, allegedly.
Dude that’s expensive maybe I won’t do coolant but just trans
How about how many quarts of trans
Allegedly about 7 quarts
What type of trans fluid ?
Toyota dealer wanted 18$ per quart lmao I said that’s too much
Great question. The spec you’re looking for is ATF-WS or sometimes just referred to as WS. Hit up your local parts store and they can help you find a fluid which meets that spec, it will say so on the bottle.
Does it matter which brand or is that vaso brand good
This brand best to use ?
Also 18is too much per quart right
As long as it meets the WS spec, you’re good to go.
Yeah $18 is steep - I’ve encountered some super specific fluids on some cars, but that’s not required for this.
Also I bought a gallon or Toyota coolant for 30$ did I get ripped
For the genuine Toyota stuff it’s about what I’d expect. I’ve paid about $25/gallon for coolant when getting from dealers.
What fluids do I buy from Toyota
Really, there shouldn’t be any reason to go to the dealer for fluids, there’s aftermarket stuff that meets Toyota’s specs which will do just fine. That said, coolant is really easy to make a mistake with the wrong stuff and that can turn your coolant into jelly, so Toyota was a safe bet for that
If this was an LFA they probably have some super specific fluids haha
I want an lfa lmao
Same haha
Ok so do I change the trans filter or just flush and change fluid
See what your auto shop teacher thinks. I personally am a “change the filter” person but he or she has experience doing this and you’re best following their plan.
Can I get filters from auto part store or is that Toyota dealership order
Parts store will be able to get them. They’ll have oil filters in stock on the shelf but they may take a day or so to get a trans filter out of the warehouse if they don’t keep one on the shelf
So then maybe I won’t be able to change the filter tomorrow
Meaning if I do I should wait but do trans filters need to be changed anyways
Since this is a bit of a Hail Mary pass, I’d say skip it for now. We are hoping fresh fluid fixes the transmission but if it doesn’t, you may be looking at a more serious repair job.
It’s not noticeable only sometimes when I hard acceleration at 40mph
It stutter for a bit or on come start reverse won’t work unless I go out of it and back in it
Yeah that’s why I’m hoping it works - usually most people don’t notice til it’s too far gone. You at least have good odds.
Yours is only just starting to show symptoms. Lot of folks wait way longer haha.
So by changing it now while it’s slightly slipping is good because old fluid causes that? Keep in mind mines at 77kmilrs
Can I fix them permanently by changing fluid or no because I’m worried I don’t want to repair transmission
If it works, then you’ll be good for a while. Change the fluid every 50k after that and you’ll be golden.
So slippage and lag is normal with old Tran fluid ?
It can be, yes
And that whine like a hell cat is normal when flooring it hard?
Sounds like the engine is supercharged in some times it’s pretty cool
That whine is probably not a normal sound. I’d suspect a pulley or belt may be starting to make some noise. Ask your auto teacher how to inspect the belt and pulleys to see if they’re in good condition.
But focus on the transmission at the moment, that’s you’re immediate concern since that might be a big repair
The whine is only when I floor it from 0-80
And wait is my transmission going bad or no I’m lost so wait I had symptoms of bad trans but does it mean I need to flush fluid or does it mean damage is done
We don’t know if your trans is going bad. It might be fine or it might not, you won’t know until you get some fresh fluid in there and see if it’s still doing the same thing
👍I’m scared but here we go I’ll fill you in tomorrow
Fingers crossed 🤞 good luck mate
First flush in my life 👍😔
@errant nebula this smoke a concern it’s 21 degrees
It was like a thicker smoke that went up pretty high that normal
@errant nebula it seems like for tmr im just going to do trans fluid empty not flush. i was reading and it said it can be harmfull so exactly wht u said. so im just draining old fluid
You may have stumbled upon the opinion out there that getting a transmission flush for your car will actually make it worse and end up costing you $1000's!
Well it's only partially true.
In this video we explain what exactly a transmission flush is, when it may be appropriate, and most importantly, that there is a much better way to maintain ...
@errant nebula My car at 77k miles hasnt had trans fluid draind or flushed. I was told not to flush so i wont but if iwant to drain the 40-50% oild trans fluid out. do i buy toyota/lexus trans fluid from the dealer themselfs wich is pricy or go to auto zone and buy the same type of trans fluid. Im more worried about mixing the wrong ones together. also is replacing the filter worth or no?
Here’s what the dealer did to it at 76.4k miles
GG @lyric mantle, you just advanced to level 12! Chat more to level up and earn top roles!
Here’s some of the things the dealer did before selling at 76.4k miles
Oh ya and those records are from 7/20/23
so it seems like the car was barley driven for around 2 years putting only 400 miles in those 2 years. Idk if that’s bad or not
And should I still drain the trans fluid or. No
I’m getting the dealer records tomorrow on what they did to my car right before I bought it
When you come back please answer any of my questions
Oh that’s interesting - they replaced the transmission fluid already. Hmm.🤔
What I would do here is a drain and change the filter, then fill. As noted, it only gets about half the fluid, but less risky than a flush. I wouldn’t see a reason to get the Toyota fluid as long as the fluid you get days WS or ATF-WS or maybe Toyota WS on the bottle (maybe in small print on back they usually list a whole bunch of spec ratings)
At the moment, I don’t see an immediate cause for concern on the smoke, but let’s revisit that after dealing with trans
Some cars produce way more vapor than others.
So I’m sure you are fine, for cannon cold start up my Toyota doesn’t really “smoke” up as much. But my Subaru, my brand new Subaru, is like a smoke bomb. Mind you, I see temps as similar or colder. Like right now it feels like it’s 11 degrees out.
On the topic of the trans, you bought this certified preowned right. I wouldn’t touch the trans, I would have a transmission shop look at it
If the information is bad, then take that to the dealer and have them repair it
Oh good call - I didn’t realize a warranty may be in play here. If there’s a warranty, don’t listen to me 
No warranty I’m cheap lol
2 years ago only putting 400milrs in 2 years
Aftermarket filter works right like from auto zone or do I neee exact filter
You can use whatever brand your local parts store has
Mixing won’t ruin the Toyota trans fluid ?
There should be a factory/drivetrain warranty
That’s what makes this a certified preowned.
For the fluid, make sure the bottle says Toyota WS or WS or ATF-WS. Brand won’t matter as long as the bottle says that. But you definitely want to double check if that car is CPO it may have a warranty with it.
How do I check that I thought it was certified
How do I check that can you tell me asap I’m probably just gonna check fluids today
But still where would I check
You told me it was certified preowned lol
The dealer that sold it to you can tell you for sure. May be fastest just to call the salesperson
What’s another way
Unless the cpo warinty was what they gave me when j bought the car. It was like 250miles or 5days after purchase until it’s voided
It will be in your paperwork from when you bought the car. https://www.lexus.com/lcertified/certification-warranty
Did they sell it as certified pre owned?
My trans fluid is pretty low
Oh there’s a specific method to check it - usually with the car running, at operating temperature, and in park.
Double check the owners manual to be sure
I am I’m letting the car warm up again before I check
Bad sign I filled 2 qrtz of fluid while the car was warm and running it didn’t fill up all the way but I can visibly see more fluid pump
So am I cooked @errant nebula
Ok - don’t add any more, but next: put the shifter into each gear for 3-5 seconds, then back into park. Shut it off for a few minutes. Start it up, take it for a test drive, see if it still slipping.
So next step is drive it for a week and re test fluid and add more if needed ?
I’m worried I filled it up wrong
Like was I supposed to fill while car was hot and running
What I’m tryna say did I mess up by adding more fluid if I didn’t fill it right like does the car need to be on or off cause I did it while on
You didn’t hurt anything by adding fluid while it’s running, but now you are at a point where it’s a question of whether adding fluid fixed your issue. Let us know how it drives!
Oh my I does pickup a lot quicker when I punch it now but yes I was worried I filled it incorrectly also I used vavoline atf Ws synthetic fluid vs Toyota because Toyota was charging 20/quart after tax while auto zone 10
I should still top it to the right level in a week correct ?
Check the level in a few days, and add if needed. I’d be surprised if you were more than a quart or two low
I bet you’re probably spot on after today
Well it wasn’t over filling but ya I could definitely be just at the right spot.
Dumb question, can you post a pic of the dipstick?
There’s no trans dipstick lol
Ok I was worried for a minute. How were you checking the level?
From the fill hole
Ok perfect. You did good.
You turn car off while warm out my pinky in and dip it. It was bone dry on my pinky so I knew I had low trans
But when I filled it I had it warm and running
https://us.lexusownersclub.com/forums/topic/46610-transmission-fluid/ has some specific instructions- sounds like you already did what was needed
Yo Tysm didn’t they had these online
That’s cool, they even specify to add it while running, so you definitely did it right!
Lol I was nervous at first b
Teachers thought I was crazy for asking so many questions like I’m just trying to learn I learn better double triple asking them lol
Things to note with the car
Trans fluid needs to be checked and possibly checked again. Power steering keep an eye out for leaks as they replaced it at the dealer with a junk yard or scrap power steering Collum(it had yellow marking kn it) then check coolant and possibly drain and replace. Most importantly the engine tick on acceleration
@errant nebula I’m just confused why the fluid was so low
If it wasn’t a dealer that changed the fluid, it’s a good chance whomever did it, did it incorrectly.
2 years ago it said the dealer did a drin and fill
@errant nebula is it normal for the cars trans to not be as smooth in the cold ? Like the first 10minutes
Yep. When you start getting into single digits, stuff takes a bit to get up to operating temp and aren’t always as smooth as normal.
Yes and especially on higher mileage equipment as well.
Like my previous Altima hated when it wasn’t fully warmed up. Once it was at operating temp it was fine
Temp gauge went to mid but car was running for 10 minutes
From a cold start?
