No clue on mileage. It came with one of my motors. It has everything that came with it like the solenoids, torque converter and mounts. I doubt theirs a need or want for the auto but if anyone would like it make me an offer. I'm never going to use it and I'm tired of moving it around the shop. Include a shipped add on of $100. The last trans I shipped was $80 but that was years ago.
