6HP19 Transmission Solenoid Kit for BMW X3 X5 for Audi

The automatic transmission solenoid valve is an important part of the automatic transmission control unit, and its role is mainly to control the flow of hydraulic oil according to the command from the driving computer, so as to realize the operation of the transmission shift. The working principle of the solenoid valve is similar to that of the hydraulic valve in the electronically controlled hydraulic system, but the working pressure and flow of the automatic transmission solenoid valve are relatively small, because the internal actuator of the automatic transmission also requires precision control.

Do not work after power on.

Different kinds of solenoid valves

Different kinds of electromagnetic valves (30)

Check whether the power supply wiring is bad → Reconnect and connect the connector.

Check whether the power supply voltage is within the working range-→ adjust to the normal position range.

Is the coil desoldering → re-welding?

Coil short circuit → Replace coil.

Whether the working pressure difference is inappropriate → adjust the pressure difference → or replace the corresponding solenoid valve.

Fluid temperature is too high → Replace the corresponding solenoid valve.

Impurities cause the main valve core and moving iron core of the solenoid valve to be stuck → to be cleaned. If the seal is damaged, replace the seal and install the filter.

The liquid viscosity is too high, the frequency is too high and the service life has reached → Replace the product.Do not work after power on.
