Yes it should be the same AT as the VII GTA.
Mind if I ask you why now you're looking for an AT sedan? Coz you already have the Lancer GT and the BMW E46, both AT cars. Wouldn't it having another AT car is just like more of the same? That's why I still suggest you to just focus on getting a proper manual Evo, unless you really have changed your mind now.
Anyway in case you seriously consider an AT sedan then I may suggest another car which I drive daily now, a 2008/09 Toyota Mark X 250G (GRX120). This is exactly similar to the Lexus IS250 (same engine & gearbox, very similar suspension and brakes too) but much cheaper. Solid bulletproof car, comfortable, very fuel efficient (easily 10-11km/ltr real average combined highway/city drive on ron95), and quite many stuff to mod. Only if you fancy luxury then go for the IS250 otherwise then better go with Mark X coz it's cheaper and actually lighter with slightly more powerful engine, yet more spacious especially at the rear. The car may look uncle-ish in stock but there are plenty of cosmetics to transform it to look more stylish. This car certainly way much better than any other Japanese d-segments out there (Camry, Accord, Teana and also Mazda 6). Apart from the Legacy GT, I think this car should be a better choice than all your other options (with regards to fuel efficiency and parts availability especially for exterior & interiors this car certainly beats the Legacy too).
