Hi Subaruguy and welcome to the BB. If you can elaborate on how your Alfa transmissions are used, and how they are failing, there will be lots of information. FWIW I instructed a Subaru Legacy owner in a SCCA Autocross driving school last Sunday, and he was relating how the early Subaru WRX gearboxes were very fragile (I saw one fail completely at an autocross "launch" last year)
