206 Automatic Gears: Rev Issue When You Release the Gas

Hello, my car's transmission was overhauled. Mail brand solenoids were installed and everything was completed at a private service including transmission oil. There is no fault. My only problem is that when I accelerate with my car, I noticed something in 2nd or 3rd or 4th gear. Depending on how I press the gas pedal, for example, at 70 km/h, the vehicle speed can be 3 or 3500 km/h. When I take my foot off the gas, it suddenly settles between 1.5 and 2. If I do this in 2nd gear, the speed settles between 1 and 1.1. However, I don't fully understand if this is a problem because I know that when I take my foot off the gas, the speed should decrease slowly and steadily. Let me repeat, for example, my speed is 80 km/h and we are in 3rd gear, let's say the speed is 2.4. If I press the gas a little, if I suddenly push with my foot, it approaches 3 slightly. If I decrease it, the pressure goes down to 2.2.

This is normal. The more you press the accelerator, the faster it downshifts and the faster it revs. This is to prevent the car from upshifting and stalling during overtaking or rapid acceleration. The ECU (brain) adjusts the vehicle's RPM based on different scenarios. For example, you're driving uphill and coming to a flat road. Even if you drive on a flat road for a while, it will continue to increase RPM and shift gears late, until you lift your foot off the gas pedal slightly. This is because you pressed the accelerator pedal more than necessary during the climb. talip2062024-10-26 11:28:36

The car doesn't change gear. If the revs are 2.5 in the same gear, at the same speed, pressing the gas pedal a little more makes it 3.3 or 3.2. When I let go, it settles into 2nd gear again in the same gear. Normally, when I took my foot off the gas, the revs would drop slightly when I had a Hyundai i20. This car seemed strange, it's normal, then I understood.

Does anyone understand my problem? I couldn't understand. Let me repeat: the car starts after 15-20 minutes of starting. This happens only once and it always works like that. For example, I'm on a flat road and I'm at 70 km/h in 4th gear and the rpm is 2.2. When I press the gas a little bit it should go towards 2.3. The car starts from 2.7-2.8 rpm as if that's the rpm of that speed. Then when I release it slightly it drops to 2 even though it's in the same gear. Normally this doesn't happen in the first 15-20 minutes. When I take my foot off the gas, if it's 2.3, the rpm decreases normally to 2.2-2.1. Why does this happen?

Does anyone have an idea? I couldn't find a solution. It fixes itself when I turn the ignition off and on, then it breaks down again. The only thing that hasn't changed is the transmission board. Should I change it?

Friends, does anyone have any ideas? My car's transmission has been revised and the brake callipers are still the same. There is no such thing as snow, moeu, etc. When the car is in 4th gear, it seems like the clutch is disengaging. The tachometer is 2.3 and suddenly goes to 3. When I release the gas, it goes to 1.3, then 1.2. When I press the button, the revs increase again and the speed starts from 3.0. Do you think the transmission brain is faulty?
