I can't switch from 3rd gear to 4th gear

Hello friends. I have a 2006 model 307 automatic vehicle.After about 2 months ago, I was giving automatic Gear fault alarm and turning off the alarm within a few seconds. I went to the master. It came smoothly. But yesterday, when I went to the izmit, I noticed that it was not 3 to 4. The engine speed is 3500, and the speed is between 120-130, but 4 throws and the vehicle did not relieve itself. He has been knocking at the gears for a few days. I would be happy if you share your thoughts with me

There is something that I learned very well from this job. Room solenoid valves were not broken, hobaa was broken. I changed it twice.

My advice
1- Check the hydraulic brain, if it gives pressure failure, take it out of the way.
2- If the transmission bushings are dead or so, it makes sense to make a revision

I mean, I think this is a lot of money until I say this is this, no one gets up and does not say change oil, change valve, it is running for 2 months at most, then it turns back and it becomes like that, it is afraid that I will go car.

Thanks so much. That's how much I pay for it. What is the estimated cost of this I need to do

Well, only for the hydraulic brain revision, it turns out to be TL 1,000. My gearbox was quite worn out of the turbines or something, so I gave 3,250 TL with a 2-year warranty. The place where I went is very technologically comfortable and I made it comfortable.

Anyway, do not just say okay, do not get it done right now, investigate well where you are, I asked the first guy when he starts from 2, we understand that he can hold up to 5, sell, sell, get some cool people. Do not break your spirits, there is nothing to do, but stay away from places with too many digits and places that cannot solve the problem for sure.
