Are you getting the prelude tranny with the engine? If so, then you should be getting the Tranny ECM with the swap. A full swap should come with both ECMs. A customer of ours ordered a 92 H22a with Auto tranny from raceup.com, and they sent the ECU + TCM. But they left out the driver's side mount, which we really needed. But thats another story. You should ask to be sure.
