A340E and A341E auto gearbox has the same control, just a different gear ratio.
Note: MaxxECU PRO is required to control this gearbox.
Note: Line pressure monitoring is required.

Example Auto transmission gear selector input to get a desired gear.
If the common terminal is GND, any DINx can be used.
If the common terminal is +12V (stock configuration), DINx where the pullups can be disabled, or 0-5V AINx must be used.

Other inputs
Speedsensor wheelspeed front = Input shaft sensor (VR).
Speedsensor wheelspeed rear = Driveshaft sensor (VR).
Gearbox oil temp sensor = Any Temp AINx.
Brake pedal/stop light active.
Auto transmission manual mode switch (optional).
Transmission DOWN shift (optional).

Low driving outputs
Connected to a MaxxECU PRO GPO 23-30 with 12V flyback (CMC4: F1) to transmission +12V supply.
(Or any other outputs with external flyback diodes.)
SLU = Lockup solenoid.
SLN = Accumulator solenoid.
SLT = Line pressure solenoid
High driving outputs:
S1 = Shift solenoid A.
S2 = Shift solenoid B.
