Emergency 3008 automatic gear knock

Guys, I need your urgent help. When my fully automatic 3008 petrol vehicle changes from "P" to "D", a knock knocking sounds and the vehicle wants to jump forward. I thought I did not press hard on the brake, but it happens the same if I apply the brake. It was the first time today that was not before.

I checked in the forum, but I could not find a very clear answer. A friend said he could be a shock absorber, and I can say that I fell into a pit today. What do you think is the problem, what is the solution, how much it costs, is a serious problem. Thanks in advance ...

My teacher was in a car hill when he did this.
If it made slopes, you may have loaded the load to the transmission while parking.
If it is done flat, the brake sensor is not engaged. Observe, if it continues again, replace the brake sensor talip206 2017-09-22 22:30:26

No, master was the straight road, I noticed when I parked the car. I even turned it on and off, I did it back and forth, but every time it turned to "P", it bounces forward and knocks

In addition, even if the automatic parking brake is not on the flat road, I do not pull my foot from the brake to get on the load transmission. a Virus 2017-09-22 22:34:19

The brake sensor may then be faulty. Pump the brake pedal hard several times to see if there will be any improvement. Of course, these are conjecture. Show the healthiest to the master

Interestingly, when I went to the service, there was no problem. When I wanted to show it to the master, it did not cause any trouble. But thanks to the masters, they still connected the machine and practiced gear. Thank you for your interest

Sir, you need to replace the brake sensor with the original one first. It's not a very expensive piece. If not, there are other possibilities.
