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.

 

 

Selector switch inputs

Auto transmission gear selector A = L.

Auto transmission gear selector B = 2.

Auto transmission gear selector C = D.

Auto transmission gear selector D = OD (optional) .

Note: Input D: active D = 4, inactive D = 3. If not setup D = 4.

 

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 up/down shift (optional).

 

 

Outputs

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.
