Automatic transmission valve body. Control block.
The first desire when repairing an automatic transmission is usually to level the valve body. This usually resolves the first cause of automatic transmission malfunction contamination.
The second desire is generally –  replace the valve body in order to quickly and not worry about diagnostics. This often leads to frustration and attempts to return the valve body to the seller with a “doesn’t work” complaint.
The valve body is a very expensive assembly, which is worth purchasing only if each element of the transmission has been checked and assembled correctly and the valve body specialist is absolutely sure that the problem (wear) remained only in the valve body itself. valves.
The transmission brain.

The hydraulic valve plate (Valve body, valve body, valve block, “brains”) is the “dispatcher” of the automatic transmission, the automatic transmission assembly, composed of valves, solenoids, sensors, galleries and channels that connect.
The valve body, like a plate with transistors, converts electrical signals from the control unit, distributes/directs oil pressure from the pump to the desired clutch drum to change gears in an automatic transmission or block the torque converter.
Many of the designs tested by race car drivers worked for automatic transmission, shifting up or down instantly and unambiguously – this is how the automatic transmission “modules” are programmed and according to the most efficient scenario and economical, switching is carried out: squeezing the clutch of the working clutch pack – equalizing the shaft speeds – engaging the clutch of the next speed.
All the technology for shifting to another gear was worked out by the designers so perfectly that the difference in power in the smartest 6 … 9-speed automatics during acceleration is less than 0.2 seconds. That is, almost infinitely.
The central (module) settings were adjusted to save fuel and optimize acceleration so that the driver can extract the maximum from the engine in the most loaded and aggressive modes. And the slightest sticking of clogged (or worn) valves first leads to jerks when shifting, and subsequently to clutch slippage in general.
