Customer: replied 8 months ago.
he has, some dealerships say the transmission has to be for a d13 and some dealerships say a d16 transmission will work. so I am confused will it work or won't it work?

Unfortunately I do not know for sure if this will work but I know in some cases either may work as long as it bolts and connects up properly but it remains to see if the dealer can update programming to make it compatible.They sometimes have to contact their tech support to see if any updates can be obtained or any modifications are needed and what is needed to be sure.If this was already checked into or is not an option let me know.
