I voted NO but this is the rule :-
23. CONSTRUCTION RULES - GENERAL
23.1 Two wheel drive cars (2WD) are those having only one pair of driven wheels on the same axle. Either the front or rear axle may be driven. Four wheel drive (4WD) cars are those having all four wheels driven.
Maybe it should say that we can not have a second gearbox in a 2wd car. Dont know how to school this to be honest
