Eh I did some minor research and found out that the trannies aren't the same. The motor is but it also sits 180 of the eclipse mening exhaust rear and i/m front so the tranny sits on opposite sides as well. So in theory the block is the same , it can be done. most likely need all the mounts from the old motor in the eclipse and you should be safe for the most part minus the sensors and crap because I dont think they have the same ECU.
