id help, but i have 2 physics lab reports due tomorrow morning, so my brain is already hurting, and i work later today. i can tell you that most engines are only about 20-25% efficient, transmissions are 90-95 for manual and for automatics as low as 70%, like mine, and up to maybe 85-90% for new dual clutch auto's.
