Not by a long shot. As you can see what can be gained in durability and performance with quicker shifts. Overlap is also extremely important. Overlap is a condition caused by applying a gear before the previous gear has been released. This is the largest problem with the 2nd gear OD that our tranny has.
<P>
Excessive overlap converts engine horsepower into damaging heat and causes clutch wear, band wear, shift delays, short oil life, and increased gasoline usage. Although it is not possible it would be like having the car in 3rd gear and 4th gear at the same time in a manual at some point the weaker gear will give way. But the pressure and heat that is applied to both also determines life of the components.

***Factory programming includes an excessive amount of overlap. ***

This is done purely for smoothness. Overlap causes delayed shifts. Overlap is the main cause of shift delay, or hesitation when shifting manually.
