My 2005 2.0XT Forester has an auto gearbox problem, most likely the front diff, causing juddering slow speed on lock.
The UK "Main Dealers" are useless, the first said it needed a new rear axle (!!), the next identified the problem by driving it in a tight circle until it wrecked both front drive shafts (outer CV joints), then couldn't wait to wash his hands of it - saying "we don't do gearboxes".
I bought a second hand gearbox, and now cannot find anyone to fit it. There are as many reasons as "specialists" I have contacted, but mainly "don't touch Subarus" or "don't do autos".
Brilliant for a 23,000 mile vehicle.
