I guess one can now buy the 10L90-E Supermatic transmission from Chevy Performance: 10L90, Chevy Performance
I like a manual transmission, but the NV 4500 in the truck now is not that stout when connected to 700 lb/ft of torque and the ratios are wide. Having 10 gears and 3 overdrive gears would be smooth as silk and likely get me a significant improvement in fuel consumption. A 4.70 first gear is more than adequate given the 3:1 reduction in the transfer case and the 10L90 is rated at 715 lb/ft from the factory. I would need only connect the TCU to the controller, and the calibration would be very close. Some tuning to address the weight of the truck might be necessary.
I remain amazed at what we can buy these days in terms of drive train options.
