I am installing a SiR B16 with LSD cable trans into an '89 civic SI. JDM engine came with electric VVS sender mounted on trans. Removed sender and now am looking at an adapter bolted on the trans with 1 bolt. Cable from 89 SI requires a different adapter for the cable. Can I just unbolt and swap adapters? I saw some info somewhere that if the adapter is unbolted from the trans, the pinion will fall off inside the transmission. True? I an't seem to find an answer to this problem anywhere and it must be the same for all SiR B16 swaps isn't it?
