More ratios give better mileage and lower emissions plus clutch to clutch operation controlled by a computer which these are uses less moving parts and lowers cost. Soon there will be 7 speed boxes and then 8 speed from GM. BMW/Benz already doing 7 maybe 8.
As customcam mentions my 68 Camaro with A6 runs well. About 8000 miles so far.
But...yes 4L60/65 is certainly simpler and lower cost plus easier ground clearance on older cars.
