Pure EV simulation

hi there, i'm trying to simulate an electric vehicle using SimPowerSystems and simscape. i have used simdriveline to simulate vehicle dynamic and an AC machine from SimPowerSystems. i should couple ac motor output torque to the gear box. however, the problem is that i'm not able to do so. i obtained motor's electromagnetic torque, however, it cannot be connected to gearbox's input.please,help me to make this thing done.

regards,
