2005 Legacy 2.5i auto trans. (4EAT-S)

[Jerry McVey]

Question for anyone who knows about the automatic transmission on this
car. My previous Subaru was a manual and I knew it was a 50/50 split.
I've read the auto is usually 90/10. However, I've also read that at
lower speeds when the auto is in 1st or 2nd gears it's actually 50/50
and once you are moving faster (i.e. more highway speeds) it goes to
90/10. Anyone know what really happens at what speeds?

Thanks,

Jer

I have a 2001 Forester-S with the 4EAT and here is what I know. I am
not sure about the 1st or 2nd gears at low speed is 50/50. But I do
know:

1.If you accelerate from a standing stop it is at least 50/50, the TCU
senses the car being accerlate from a stop and automatically sends
more power to the rear wheels.

2.If you accelerate either from stop or rolling while driving up the
hill, power is transferred to the rear wheels.

In general the Auto-AWD is very dynamic. A lot more dynamic than most
people think, ie Some people think it only transfers power when it
slips, and this is not the case.

Jerry Subaru Legacy as well the OB 2.5i have a dynamic AWD. I just switch
from a 1999 OB with 116,000 on it to a 2.5i OB 2005 and based on my
experience, it does not matter if it is 50/50, 70/30, 90/10 or whatever
because the AWD system is Dynamic and it changes as the circunstances, road
conditions and vehicle dynamics dictates. So don't pay attention to the
technicalities and enjoy the ride. I have done it in three OB 1999, 2000 (my
wifes car) and 2005 (My new OB). Believe me it it very hard to part from
such a versatile and safe car.
