I think the T/A was only on the 220 hp 400, not the standard version. I can't recall the standard 400 HP but it was better than the 403 / 180 hp. Does W72 sound familiar, that might have been the 220 hp engine? I remember WS6 was a handling option? Included 4 wheel disc brakes?
I know if it was as easy as the sticker they wouldn't have had us checking VINS for codes. 2ยข
