HI there,
Lets be clear about this much.
The 6L80 has absolutely NOTHING in common with any other transmission as far as parts, castings or design.
The only similarities I can see, is the function of the shifting is very close to the Allison 6 speed in the 2006 trucks.
Clutch stacked shifting, no accumulators and incredible torque potential are substantial.
Plus it has the control module INSIDE the transmission housing.
This fresh design and simplicity as far as the clutches, valvebody and shifting pressures are the wave of the future and the front drive 6 speeds that are coming will be using similar technology.
As far as automatics in sports cars are concerned, this unit is cutting edge and very reliable so far.
Allthebest, c4c5
