I imagine it would physically fit, but keep in mind the SC400 of that year uses the A340E while 1st gen LS400's use the A341E. The only difference between these two transmissions is the 1st gear ratio. It's shorter on the SC400. I'm not sure how this would affect your speedometer. You'd probably be better off finding an A341E.
