Toyota Grande CVT Gear Problem

[pwuser151804282637]

Yeah bro , No problem thats fine.
Yes exactly thats something related to lockup.
I will Monitor lockup solenoid behaviour during drive soon inshallah. Maybe it will help us track down the root cause.

And yes it is surely a issue that many people have experienced. Bcz i didnt took car to moon neither i drive it with 2 foots. I have driven the car with light foot and high care.

There is a product I have used here in USA to remedy the drone and shaky tcc lockup behaviour, Its not sold in Pakistan. But its a one shot chance, meaning if it doesnt help then you need mechanical work done in the gearbox.

With all the French in this thread
Net conclusion
Bawa ji gear baxa khul c

His gear is perfectly fine. If he still wanna open then its his choice. This jerk at 40 is normal. Gear keeps on changing cvt ratios coz this gearbox k313 got fake shifts.

Fake shifts, a new term for me at least. What does this mean?

[rajaatta]

At last some one to recognize the fake shifts ....

Fake shifts, a new term for me at least. What does this mean?

Yes these are fake shifts.
Connect toyota techstream and lift the foot off from throttle at 40km/h. Software will show 2nd gear and when you press pedal again lightly then software will show 6th gear. In a real world cvt doesn't have any shifting involved. These are fake shifts introduced by aisin japan in k313 cvt which offers sporty feel when driving fast.

At least they gave new generation of cvt, but sadly even stealerships don't know how to change its oil properly.

Yes i have observered it every time Driving on light foot.
I think its a feature to maximize the economy. Car shifts into higher gear at low rpm to get max speed gear efficiency.

Another rocket science i wana share here ,

When the eco mode (aka indicator) is on the jerks are Higher and noticeable for passenger aswell.
But if we turn it off They reduces and the passenger doesn't notice much.

[pwuser151804282637]

Can we Control lockup soleniod on and off in techstream active test? Or any way to do so.

And anybody knows where to find repair manual of corolla for knowledge purpose.

[rajaatta]

texhstream is not for playing purpose........

[capsat]

so far Techstream is used as diagnostic tool not a tweeker during drive.

@Xulfiqar to sum up i believe gentleman is overly senstive to feel CVT SHIFT JERK, - may be the other vehicle he uses is non-cvt. seems like the case discussed about Corolla X 2004 in DXB and the Gli 2005 from ISB i got rebuild back then in KHI.

[Xulfiqar]

I think he wants chevrolet and mercedes type shifting behaviour from that cvt.

Brother pls read above reply carefully , Both cars i tested were altis grande - 2016 and 2019 facelift model respectively. Pls Dont respond like the dealership 🤣
(Ah its Normal and completely fine all grandes do this) and when u drive other grande.s in real They dont actually do so.

[pwuser151804282637]

And yes it is used for tweeker proposes for diagnosing if you have ever used it or will use it dont forget to check active test tab

[capsat]

I stand by that - apka Wa_ham hai -

you want to spend money to tear down source parts attempt to fix it it will not change a bit.
please go-ahead its your money. unless you are trying to experiment over some customer's hunch and fuel it by agreeing to his doubt., at his cost.

Thanks for your assistance and Reply on the thread , You tried your best to help. And i learned some useful information aswell. But the cause bcz of which this thread was created is still here and we failed to track and find the culprit.
Soon inshallah i will find the cause and update on forum so anybody else can benift or find some information here.

Bhai kisi kay pass itna time nai hota wo wehum ki waja sey thread khol kr beth jae or discussion or debate krey.
Apko nai manana tu bhai nai mano ,
You never drove the car and you are saying wehum hay. Amazing. Atleast 5 drivers have test drove my car and all have said there is problem but nobody knows where it is coming from. Anyways thanks for your time and discussion appreciate it.

what seems rocket sciene to you is engage & dis-engage jerk of over drive check the rpm meter when you click eco on off
