They do indeed, but your post was somewhat vague, hence my flippant response
Anyway....
You need either an 02E DQ250 6 speed DSG from the MK5/6, or a 7 speed DQ500 DSG gearbox from the MK7. The latter is more complicated electronically in terms of retrofit.
You will also need a supporting DSG engine ECU, pedals, console stick, paddles, steering wheel etc etc.
It's not an easy or cheap conversion. You would be better off selling the manual car and buying a DSG in all honesty.
