MiniMatic Automatic Transmission

The Mini did come out with an Auto. It was the Mini.Matic.

No-one is quite sure on the exact number of Mini.Matics produced, but they are around.

The automatic transmission weighs 50.8 kg (112 lb.).

A great website that contains a breakdown of the Mini Automatic Gearbox is:
