both the 97 legacy gt and outback have a 4.44 4eat, but are the ratio's for 1st to 4th the same or does each model have a seperate 4.44 transmission with there own specific ratio's

I am pretty sure you can interchange the two transmissions that year if you swap the TCU. You would also have to change the speed sensor.

have you done it? others that have swapped trans and TCU have said that it seems best to keep the TCU for the vehicle as it's programed for the particular weight/style. in other words a GT sedan TCU would be better in a GT sedan, not a wagon. i'm about to swap trans and that's what i've seen/heard out of searching here and asking.

I agree with kepping the tcu matched to the vechicle.I'm currently running a turbo tcu in a n/a vechicle,normal driving its ok but as soon as you hold it flat it over revs between gears .Put simply the shift points are different.

. You would also have to change the speed sensor.

The difference i've seen in speed sensors is not the sensor but the wheel it gets its count off.A vtd style rear transfer has 22 teeth and a clutch pack style transfer has 30 if i remember correctly.This will confuse the tcu as the counts per revolution are different.I don't think it will be a prob with the mentioned auto boxes.

to the OP - the gear ratios for auto trans are hard to come by. there are links to pages with massives amounts of info on manual trans, but the auto trans stuff is harder to find. probably easier to stop at a dealer and ask them, it should be in the FSM.

what's the difference here and which transmissions had which style?

I have done it a few times. The reason I used the TCU with the trans is because it was stated to do so on the Hollander interchange I use. They drove and shifted perfect. You would be fine either way.

cool. others have seen bad shifting when swapping the TCU. i ask if they have the TCU if i'm looking at a transmission. for $50-$100 it's worth it to have on hand.

Vtd is on wrx and tt in australia ,not sure in the states if it was the same.The vtd[variable torque distribution] transfer has a planetery gear set and clutches it is more rear wheel bais .Clutch pack transfers were pretty much on everything else.
