Can a shift solenoid be used in an AX4S transaxle?
This means that the AX4S Shift Solenoids can be used in AX4N transaxles, but AX4N Shift Solenoids cannot be used in AX4S transaxles, as there would be no diode protection. Most suppliers stock only the AX4S shift solenoid, as it works well on both.
Are there diodes in the solenoid of the AX4N?
Shift Solenoids for the AX4S have a diode in the solenoid, and Shift Solenoids for the AX4N do not have a diode in the solenoid, as the vehicles equipped with the AX4N have the diodes in the processor.Some car tools such as OPEL EDC16 KM Tool and BMW and BENZ Scanner are helpful to you.
How is a shift solenoid in a transmission controlled?
These shift solenoids can be controlled by either the ground or the power side of the circuit. On some transmissions (usually foreign) the solenoid is controlled by a 12 V signal from the (TCM) transmission control module.
What to do if your transmission solenoid is not working?
If the scanner described a high power circuit code, check the solenoid’s ground side and follow the flow chart. If there’s a low power code, use the DMM to check the solenoid’s power feed. Automatic transmissions use two or three solenoids and turn them on and off at different times to achieve different gears.

Where are the solenoids located in a transmission?
When the TCM triggers this coil, the plunger moves, allowing pressurized hydraulic fluid to flow to certain parts of the transmission. This allows the transmission to shift into the desired gear. There are two or more shift solenoids inside your transmission. The solenoids are typically integrated into the transmission valve body.
How does a solenoid get power to shift gears?
The transmission control module (TCM) — the brains of the transmission — will send power to one of the shift solenoids in order to shift gears. Inside the solenoid, there’s a plunger surrounded by a magnetic coil.
