I have a buddy selling me his JDM auto VTEC tranny. He says it has somesort of TCU with it (TrannyControlUnit) and near the stickshift it has a 'sport mode' option.
My tuner mechanic says he thinks it wont be a problem installing the tranny to mine but doesnt know about the extra tranny computer. The guy selling it said that the TCU thing was located under the passenger side floorboard. I told him it might be the ECU, he doesnt think so. So what do I need to do to get this auto JDM VTEC tranny to my Auto Si Tranny? anyone know.
