Hey guys,

I'm reaching out to the forester guru's that know their stuff. Looking at getting a replacement 4EAT for my '05 Saab 9-2 Aero, which has a final drive ratio of 4.11.

I saw somewhere that some of the Forester XT 4EAT had this same final drive ratio, can anyone confirm? I think it's 06-08 that has this 4.11 final gear ratio.

Seen in this post:

Can anyone else confirm this? I'm looking to get a 4.11 4EAT transmission, and they are rare to come by in the WRX, may have more luck finding one from a FXT.

Thanks,
JP

For Forester 2005 model years and earlier, it was 4.44. In 2006, it went to 4.11. I don't know if there were any physical or mounting differences, but probably not. Be aware that there is a separate TCU (as in Transmission Control Unit) in your vehicle, so that might be different. Also, the engine ECU might have a different map.

I've owned both 2005 and 2006 Foresters and the 4.11 was definitely an improvement - great on the highway - slows the engine down by ~350 rpm. What ratio was used in the '05 Saab?
