For individual internal gearbox parts and general assembly, please refer to the individual manual for the MG model you are working on.
To date, no new parts are made for MMM gearboxes (except where indicated below), but the supply of almost all parts are readily available in secondhand condition, though It should be noted that gears and gear clusters in good or little worn condition are now very rare.
WHEN ORDERING GEARBOX PARTS IT IS ESSENTIAL TO STATE PART REQUIRED AND MODEL OWNED.

Q,R,K. OWNERS – WILSON PRE-SELECT AUTOMATIC GEARBOXES.
Original MG versions of this gearbox were characterised by the bell-housing joining the gearbox itself, to the engine to which it was connected. We are rarely in a position these days to offer original MG versions of this box. but it is important to note that bell-housings and final drive shafts are now available from us to allow ‘Wilson’ pre-select gearboxes from pre-war Rileys, Lagondas and AC motor cars to be adapted to fit MGs. In the main, the adaptions are straightforward and can be carried out by us on a customer’s behalf. Please enquire for further details.
For the breakdown, operation and application of this type of gearbox we would refer you to the relevant chapter in W.E. Blowers’ book – ‘The Complete MG Workshop Manual’ .
