Three letters for you: AOD

what bout AOD

ill quote from another forum

This is what Kevin Lockliear at Dynojet had to say:

"Typically, you will see the highest numbers in the 1:1 or closest to 1:1 ratio gear. This is because no additional power is being exhausted to accelerate the inertia of the drivetrain. In 2nd gear, let’s say, because the gearing allows the car to accelerate more quickly, more HP will be used to accelerate the inertia of the drivetrain than in 1:1. See my graph below. This example was a 1996 Pontiac Trans Am WS6, all gear run. Ignore the small shift spikes at the beginning of each gear as that’s an inertia spike (where letting the clutch out abruptly against an engine with higher RPM than matching the next gear at that speed causes a brief quick acceleration of the drums).



As you can see, the HP was the highest in the 1:1 gear, and lower in other gears. From what I have experienced, the further you get from 1:1, the lower the power getting to the wheels and drum surface will be, as more is used to accelerate the inertia of the drivetrain, overcome frictional losses in meshing gears, side loading bearings, etc."
