Are we talking about a typical 4 speed automatic or a fancy tip tronic transmission complete with paddle shifters?

Most Ive seen are dc that use a stock manual tranny and no clutch that is shifted from time to time. Most AC setups are direct drive to the axles. I guess it depends on the rpms of the motor used vs axle speed at desired rpms rather any gear reduction is needed.

As a former electric wheelchair user I know the gearless brushless motors always had problems were as the 2 and 4 pole with worm and helesphere(SP?) cut gears had no problems at all. 4 pole had better battery life vs the 2 pole.
