What?Transmission I compatible with a Subaru Legacy 2013 2.5 premium six cylinder

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your Legacy's transmission might be on its last legs, especially with that shaking and the gears not catching. For compatibility, your 2013 Legacy 2.5i Premium uses the CVT (Continuously Variable Transmission) or a 5-speed automatic if it's not the CVT version. If you're looking for a swap, you'll want to stick with transmissions from a 2013 Subaru Legacy with the same engine and transmission type. Some 2012 and 2014 models might also be compatible, but it's crucial to match the transmission type and engine configuration exactly. Checking the VIN for a match is your best bet or call the dealer with your VIN and get a proper part number to use as a cross reference.
