If anyone is in the need for a S4 transmission, there are two, the origional was $3k and it was superseeded by a $6k tranny. Just don't have the tranny codes handy, however, Linda@Carlson advised me last week that she has 3 of the $3k in inventory and didn't know why those wouldn't work. Anybody know if one had to purchase a new S4 tranny, would the origional part# work. Save yourself $3k! Scott
