Hi, ive got a 2000 impreza sport which i am looking for a new gearbox for because it is whining. ive found a breakers on ebay with a 2001 sport breaking but the gear box numbers dont match. mine is ty754vr1aa but the one on ebay is ty764vr1aa. what is the difference? does the one on ebay have a hill hold function or sometime because mine doesn't. Would the box work in my car or not and if not why?or does anyone have one for sale? Any help would be much appreciated. thanks for reading Alistair.
