GM has recently announced that their engineers are hard at work on a second generation 6T40 6-speed automatic that will apparently give all cars using the transmission a 5% boost in gas mileage.
Autoblog reports that the new transmission comes from updated technology featured on the 2011 Chevy Equinox which currently touts a 32mpg rating. These updated electronic control strategies will apparently provide a 3% boost in mileage with anoterh 2% coming from the reworking of the actual hardware of the transmission.
