How to fix automatic transmission oil pressure? - 307

There is a vanity case 307` SW m. There is a new type of solenoid on it. At first, I thought that the knocks in the gearshifts might be related to the motor flap, and I had it checked. I couldn't get any results from there. I had the oil pressure measured, thinking that it would later be a problem with solenoid valves. if I remember correctly, it was slightly lower than the normal pressure level. For example, if the normal pressure level is 2.50, I got 2.40. it was something like that. While thinking about replacing the full solenoids, I learned that my solenoids are the new type of solenoids. At this stage, two questions came to my mind:

1- Can I raise the oil pressure without changing the solenoids and bring it back to normal level? is there such a method? so I think my gear shifts will soften.

2- Could the solenoid valves be broken even if they are new types? would it help to change?

also yesterday I changed the coils and filters of lpg. Interestingly, the strikes were noticeably reduced. the traction of the vehicle has become stronger. When I bought the car, I did not know when the last ones changed the filters before me. I used 14.000 km and changed it. pretty worn. In summary, the contamination of the lpg filters not only increased the shift knock but also reduced the traction. It shouldn't be neglected.

yes, is there anyone who can help me on the above issue?

Transmission oil must have completed its lifetime, it may lose its feature after warming up and make it knocked. There were a few topics about this topic in the forum. the /forum_posts.asp?tıd=17000&title=otomatik-anzman-da-vurunt

I changed the gearbox oil a few thousand kilometers ago. but unfortunately he did not make the slightest contribution. By the way, I guess I had her pressure adjusted back then. Now it comes to my mind :) then there is only one question left. could the new type of solenoid be damaged? is there such a possibility? Does it knock when it breaks?
