The automatic gearbox has its own ecu for learning the way you drive think its under the rear seat but not 100% sure.You will need pedals clutch master etc. Not heard of anybody actually doing it but a few people have asked. If it were me I would swap the loom from a manual into it but that's obviously quite a lot of work unless you were doing a respray at the same time, unless your shell is 100% I would think of selling and buying a manual
