The whole driveline is 15% on a manual. What told you the transmission was 10 points alone?
I've seen trannies weigh in around 75lbs. Yours probably differs. The tranny is for balancing; acceleration and topspeed/fueleconomy/durability(basically lower rpms).
If you don't need the acceleration
you can sell the tranny and the driveline and hook the electric motor to the rear differential.
Have you considered a hybrid system for the car? I've had an idea of using one of Ford's 2.3L longitude mount engines with a mustang tranny with an electric motor pancaked between the two, the problem is currently how to control the shaft from the ICE to the motor so that it can be disconnected while the ICE is off for electric drive and turned on for recharge and ICE cruising. I'm thinking it needs a two way locking differential.
I prefer the thought of using 600lbs for an ICE and fuel tank and only using 200lbs in batteries instead of using 800lbs to get the range of a gallon of gasoline. Even though the fuel economy will be better than stock, the electric motor gear would add another 200lbs to the mix. And it won't get the efficiency of an all electric.
