I do not know the answer to your question, but I would be very surprised if the M45 transmission fits a 1994 Q! The M transmission (well, at least the 2003 one) is a new design and has been used (in five speed versions) on the newer generation Q, current G, and 2003 M - although there are probably some slight differences in the gearing and the TCU. I do not know if it was re-designed for the 2006 M, or simply added a new gear for the six speeds.
Hopefully, someone else can chime in here with the accurate info!
Welcome to NICO anyway!!
