Gli 2015,Automatic Transmission issue

[mubashir8]

AoA everyone.
I recently bought a used 2015 model auto Gli.
Driven it 10k so far.
I changed all fluids as soon as i bought it 10k Km ago, including ATF fluid.
Anyways, so issue is that i am noticing a jerk when car shift a certain gear, i think its from 3rd to 4th..but i cant be sure. Its more pronounced when i am cruising at slow speed and then press accelerator(even slightly) for speed, i feel a jerk, RPM goes up at once from 1.9-2 to 3..
I donot feed any slippage and it shifts fine when i accelerate more right from begining.
It doesnt give a jerk while shifting on high RPM i.E when i am accelerating it hard.
I also sometimes feel a jerk when R is engaged as whole transmission is moving back underneath.
It became more prominent after i got my transmission mount rubber changed recently.
Things i have done so far

1-Engine mounts inspection, all seem fine on inspection, tranmission mount bushing i have replaced
2-Changed ATF from dealership.
3-changed plugs
Anyone can tell how to confirm if it is transmission issue or something else.
Any mechanic in Lahore who can help?
And if change of tranmission is needed, how much would a kabuli transmission of 2NZ-FE corolla engine would cost from Bilal Gunj?
Regards

i got my transmission mount rubber changed recently.

locate the vehicle ID Plate ( a silver plate either in the trunk or in engine bay ) locate Trans/Axle & share the code U-3xxx

in front wheel drive vehicles transmission & engine mount change require caution. The vehicle shall be levelled over jack stands. When transmission / engine mounts are fractured either one or both,

both need to be changed. Change procedure require balanced level vehicle and support for 1 while other is removed / replaced .

if the ustaad have replaced only 1 mounting in quick job by lifting one side it has caused disbalance and you are feeling the transmission sway at R & kick down throttle.

it is a mounting fault the transmission is working perfect do not fall trap to any tinbox classic mistry.

Thankyou for the reply.
The code is U4413-08A.
I was willing to get other mounts changed as well, as someone told me that right front mount is also faulty however the mechanic who changed the transmission mount rubber didnt change the front mounting and as per him, its fine and if needed, he will do it later on.

I got the mounts inspected from dealerhsip and a junior mechanic there on inspection told me that they look fine visually.
One thing i have noticed is that there is no jerk if i keep the car at high RPM i.E between 2-3K rpm, but driving car like this hurt my fuel average also its not possible to always drive at such high acceleration.
So it jerks when you are cruising at 30-40-50 and then give pedal, even a little bit, i guess it downshifts for more throttle and gives a jerk.
Also if i drive it on D3 continuously, there is no jerk as RMP are already above 2 on this at cruising speeds.

I am having the very same issue, but I am sure its not related to mounting. Can you please confirm if you issue got resolved or not? and how did you resolve it.
