Thanks, I had it fixed by AT Specialist. I don't know if they changed this Hall sensor or they didn't sth inside of the Valve body. This is the exact part:
"The output speed sensor (3 pin connector) RE5R05A 02-up"
Sensor cost was around 50$, whole operation was around 400$. Sensor was coming from some Nissan I think with JATCO gearbox.
