Are you sure this is right? In the recent technical briefing released by M-Power they said:

"The compact six-speed transmission with dry sump lubrication is a new development and has a weight of just 43 kg – much lighter than similar gearboxes."

"Because the drive shaft is also a new part, every ing is specifically tailored to the requirements of the BMW Series 1 M Coupé in this combination, starting from the flange of the crank shaft."

I took this to mean that it was a brand new transmission, not the 135i transmission. Assumed it was developed for the upcoming M3 because they could never cost justify a new transmission for the 1M.
