Transmission failing?

I was in manual mode shifting from 6-7 at around 3k rpm. The shift happened, but the car lurched back and forth like the engine cut out or something. I put it in comfort automatic and accelerated to 7th gear from 6th. It did the same thing. Car lurched extremely hard. I was able to replicate it about 5 times. There was no error code. It disappeared after half an hour and happened again a few hours later when I drove in the evening. This time it lurched hard from 5-6th gear while 6-7th was more subtle.

what can be the reason? This never happened before.

thats the thing I’m worried about.. I can record the video, but it won’t show the car shuddering. The only way to prove it would be to have a tech in the vehicle while I drive it. Would they allow that?

there were no lights on the dash and no messages. Everything looked normal. The next appointment is 1.5 months away. The transmission acted up again today while I was on the highway. It jolted so hard from 5th to 6th gear. It happen mostly during 5th to 6th and 6th to 7th at around 3500 rpm shift. Happens in all drive modes.

It got fixed a week ago. It was the transmission valve body.

Just an update: the problem started happening again a week after the valve body replacement. I’ve been driving the car broken since then.

Sounds like a misdiagnosis. Call them back and see what they offer.

they are going to have a look at it again. The engine is also leaking from somewhere behind the engine near the top. Quite a bit of oil travelling down. They are going to have a look at that too. My wife drives this car and accellerates like a grandma. I’m surprised this car has issues haha. It takes one month and a week for an appointment every single time here. Ridiculous!

That sounds more like a turbo issue.
