The automatic trans uses a clutch pack and piston and it is controlled by the computer electronically.There is a small solenoid and valve body in the tail housing of the trans and the computer can vary the amount of engagement of the AWD.
The standard trans uses a viscous coupling in the center differential which is in the tail of trans.The viscous coupling is a sealed fluid clutch pack.As soon as there is any wheel speed diffference or slip between the front and rear wheels the fluif heats up instantly and engages the AWD.It has no computer controls which is the biggest difference in the manual vs. Automatic.
Neither has proven to work really better than the other,both are reliable and work well.Have had to repair both types and the manual is simpler to repair and less frequent problems.An important thing to remember on the Subaru AWD is to keep all 4 tires the same type,size and outer diameter.A half inch in total diameter difference can damage awd system.

ITS BASICALLY THE SAME ONLY THE AUTOMATIC DOESNT USE A CENTER DIFFERENTIAL, AND THE MANUAL DOES .
THE POWER DIFFERENCE WITH A AUTOMATIC THE POWER IS TYPICALLY SPLIT 90\10 FRONT TO REAR EXCEPT WHEN U TAKE OFF IT SENDS MAORE POWER TO THE REAR FOR BETTER TRACTIOIN.... NOW THE MANUAL HAS A CONSTANT 50\50 SPLIT FRONT TO REAR.. SOME MODELS HAVE LIMITED SLIP AND SOME HAVE AN ADVANCED VDC SYSTEM WHICH USE THE ABS SYSTEM TO GET BETTER TRACTION IN CERTAIN SITUATIONS..

The mechanic certainly knows what he's talking about. The subaru website has some great info on their AWD technology as well as the Boxer engine.
The WRX STI has the option to change the distribution of the AWD.

basically it still functions the same way,,the only difference is the automatic is what it is automatic,,and the standard shift,is what it is,,the traction system still works exactly the same way as far as driving and handling goes,,you still have the same effect on it,as far as traction goes it still grips the same way also,,this question has came up in my repair shop before,,i hope this help,s.

Someone please correct me if I am wrong on this, but I believe there is one slight difference.
On the automatics, the AWD can vary traction on all four wheels, whereas on the manual model the traction only varies front to rear.
