Car jerk after changing CVT Transmission Oil

[haseeb.basharat]

Doesn't matter as they leveled oil at optimum point after changing. They must have given you the remaining oil can. Oil needed in this method is around 2.4-2.8L only.

Someone below car was looking when the oil drop are stopping during calibration.

At this point drain nut is opened to check oil level.
If more oil comes then its overfilled.
If few drops then oil is at normal level.
If nothing comes out then underfill.

Cvt oil expands at high temperature so its necessary to check oil level between 35-45 degrees.

After seeing/inspecting the oil, they said the oil condition is not so bad (not dark color), so engineer suggest me 4L is enough to do the job.

Change cvt oil at 55000kms or 2 years whichever comes first, and oil will remain in the perfect form.

Thanks for your detail advice. Actually they have charged me separately for calibration. On that day they have connect toyota software through laptop and shift to various gear (dashboard lights are also flash I.e. engine light )and told me this are calibration which they are doing. Next day I go there and told them regarding the jerk. They again connect the laptop and software, said oil pressure and other values are perfect. After that They said may be due to new oil and old oil mix it was happening. Advice me to Run the vehicle for one week and they hope this will be solve. Answer was not so satisfying but I had no option.
Please note that during the process they have empty the full cvt oil can which is 4liter. Sorry I was writing so many thing due to little concern of Transmission wear not happend due to this.

Thanks, I will keep that in mind for future.

Hi @haseeb.basharat, Should i ask the dealer to re-calibration ? should new oil need to put freshly to do the re-calibration? As i said, last time they put full 4L can oil in vehicle.They gave me empty can.

Should i require to flush all the oil by open the CVT oil PAN, in such case how much oil will be required ?

Thanks for your kind advice.

this may help you understand

if they have already changed the CVT Fluid no need to reflush / change. Dealership shall scan & re-calibrate the values. That will kill the shock you are experiencing.

@capsat: Thanks for your kind advice, i will ask my dealer to do that on Saturday (Tomorrow is off for dealer).

[haseeb.basharat]

Follow your dealer instructions. They have performed everything in a perfect way. No need to worry.

@haseeb.basharat: today I went to the dealer. Initially they said to overcome the issue of jerk I have to change the gear box. After that I inform the situation to their GM then he asked the engineer to recheck. Then he agreed to check the oil level and recalibrate. After checking the oil level they drain out lot of oil (A Pan of oil)and done the recalibrate. I asked them why so much oil they drain out if the oil level is ok (as mentioned earlier). They try to avoid to answer the question and start saying other functionality like the jerk may be earlier but I unable to notice, somitime it happen. Now I required a suggestion, is the jerk will cause the CVT wear or demage? Should I need to visit other workshop for remedy?

[haseeb.basharat]

If the jerks are at minimal now then you are good to go.
Nothing happens in so much less time period. Keep on driving your car. If your issue is resolved then you don't need to visit any workshop at all. What was the temperature of cvt when they recheck oil level?

[pwuser156457094182]

37 celcius. Ok. Lets drive for a month. Finger crossed. The jerk happen when the gear shift slowly but if I shift the gear quickly then jerk cann't be feel so much.

@haseeb.basharat, Today i diagnosis through the ODO scanner in different workshop and receive the following error:

Engine: P2109 Throttle/Pedal Position Sensor 'A' Minimum Stop Performance.
Air Conditioner: B1421 Solar Sensor Circuit (Passenger Side)
Main Body: B1206 Power Window Master SW ECU Communication Stop

They said Throttle need to replace and eliminate the error. Then only they can said about gear shift jerk causing issue.

I told them i will inform regarding the changing of Trottle later, preferably after EID Vacation.

remove any extra matt or carpet from driver side.

[pwuser156457094182]

@capsat: i do the carpeting after getting the car, also put rubber new mats over the original one received with car. should i need to remove both ? For one of this reason, the throttle error are coming?

[capsat]

remove rubber mats temporarily & test, please

[pwuser156457094182]

@capsat: After clean the throttle body, the error code has been removed. But still the car jerk is there when shift the gear from R-N-D or D-R only, during drive in D or R their is no jerk. What should be my next step to remedy this or should i continue with the jerk till anything new faced ?

[capsat]

try to shift between N - D | R - N | P - D
with brake pedal pressed.

CVTs does not jerk during drive thats why called turtle run

[pwuser170975057076]

have my corolla grande 2018 CVT-I oil changed by dealership (Toyota Western) in karachi.
At the time I did not about oil types and I thought dealership would know better.
Today when I checked the Trunk I found the Tin box of CVT TC oil in my car.
I am really concerned now as after reading this thread it says that my car required CVT FE.
What should I do? Will the dealership accept this claim?
