Yup. The V160 (6-speed) is a NON-SERVICABLE TRANS. If your synchros or whatnot are gone, bye bye, time for a new tranny.bgrieger said:2J fits in MK II and forward Supras with minor modification. The 6 speed requires heavy work on anything but the original, and does not fit right. To cut down on wiring nightmares, I recommend standalones for this type of swap (too damn much work otherwise). Get the 1J bellhousing and use the R154 in all cases.
