This prevents the gearbox from changing up through the gears when the rear wheels have broken traction. From what I can understand the computer detects the speed of the front wheels and references them to the rears. This prevents the car from up shifting when wheels are rotating too fast for the vehicles overall speed. Link to comment Share on other sites More sharing options...

The torque curve is flat. As long as your gear ratios keep you within the flat torque curve it don't matter if you have 1 or 5 gears.Just look at top fuelers......they run 2 or 3 gears at most..... if there was an advantage, as you are suggesting, then they would run 7,8,9 or 10 speed boxes.Sorry for the "slap stick" but Wannabe Mechanical engineer might be right...I have the bit of paper and the design time with gearboxes and diffs......Sorry.Top fuel only have a cluch pack and are direct drivePro Stock have gears 5 or moreRob Link to comment Share on other sites More sharing options...
