2005-7 Impreza 2.5L 4.11 switch?

My research shows that a 2005-07 Impreza 2.5L auto transmission should have the 4.11 final drive. A 4.11 rear diff gear set has already been installed in my SVX with a previous transmission that has been rebuilt twice. Do you think that this would be a good replacement? One was found with 11197 miles for 399 + 125 shipping. Would it be more benficial to install a 4.44 transmission and differential for $785 shipped? Any idea on how many hours either switch would take.

I really do appreciate your time and knowledge.

It won't be a "Plug and Play" swap, as the newer transmissions have different electronics....
Young Tom has done one on Melis's SVX, so he can probably help you with the details...

What would be the last year that would enable plug and play?

Which is better the 4.11 or 4.44?

THANKS

The last year for a "plug and play" would be 98.5....if it has a screw on filter on it, it is NOT plug and play.

I myself think the 4.44's are best, as they creat less strain on the transmission...but if you do more highway driving the 4.11's will do a little better on MPG

THANKS, perhaps a 4.44 switch would be best...
