Other model AT's that will fit a 99 GT foz

Would anyone know or know where I can find out which other model Subarus would be suitable donors of an automatic transmission for a 1999 Forester GT?

I presume it would have to come from another turbo 2L?
I Know Niterida did a swap from 99 GT Foz to 03 Outback, but that was from turbo engine to normal, not the other way around.

When I was looking for the outbacks replacement I couldn't find any specific info. They will all physically fit but the problem is the electronic side of it. I was told that the possibility of getting one with matching connections/connectors was slim uness I bought one from the exact same model.

So either by sheer fluke, or the above is not true, the Foz box plugged straight in and I had no issues with any check lights or shift problems etc.

Maybe try and buy a box and matching TCU or at least make sure the connectors are the same on the box you buy and your TCU. Or find an auto from a Gen 3 Outback and I'll swap it for my Foz GT one.

I think (based on my experience with earlier boxes) as long as you get the same style box and the correct front diff ratio you will be fine.

The later style boxes have a filter mounted on the box itself. Yours should have this being a 99 but check to be sure.

Just about all the 4EAT boxes in from 1990 - 1998 are interchangeable assuming you get the diff ratios right so I cant imagine it would be any different in the later style box. niteridas experience supports this.

Thanks for your offer niterida, yeah I was thinking if I got a different one I would have to get the TCU for it, I reckon you were very lucky with yours or we've all been hoaxed and most of them will just plug in and work.
Yep Vincentvega mine has the screw on filter on the side, from what I've read these are a phase 2 4EAT I think I need to look for one from another turbo car.
There doesn't seem to be many 4EAT around, I might have to bite the bullet soon and buy one from the wreckers.

There isnt a big difference between turbo and non turbo boxes, usually the stall point of the torque converter is higher and 1st and 2nd clutches have an extra plate to take the extra torque.

Thanks for the info.
