different type of transmission - has planetary gears and clutch bands.
adjusting the bands usually fixes that.

Did he experience the flare problem or did it not appear for him?

If there really is a problem, it will get worse. Perhaps the problem will even
be exhibited when the system is cold.

By the way, you can have someone check the resistance of the solenoids even when
the transmission is cold. Bad ones will still show a very high reading on an
ohmmeter.

It seems that he did not feel the flare problem. It only occurs when
pressing the gas "unusually" low.

It does not show when cold. Cold transmission shifts good.

I've adjusted my foot and now the problem seems to be disappearing.

did you get the motor maintained so it's operating as well as it can?
