Don't know anyone personally. But, I heard from forums and other guys who knew someone who ran it that is't not all cracked up to what's it supposed to be. Especially, not at the price of $6k. There are far better trannys out there.

The 6L80 is better in my opinion. Although, I have one, I don't have it installed into my truck yet and it won't be for a couple of years until I get to restoring my truck. There are certain perimeters you have to keep with the 6L80E, such as DBW, 58 tooth reluctor and if I'm not mistaken....E38 computer.

PCS also sells the Valvebody to convert a 4l80 to a 6 speed.

its a 4L80 that uses the overdrive clutch pack/modified to use the solidoinds to make it 6 speeds by using 2nd gear and overdrive and third gear and overdrive to make it 6 actual gears but it still retains the final drive ratio of the 4L80 which is .075 to 1
