    does a 4l80e take more power to turn than a 60e?

    i have heard rumors that the 80e takes more power to turn due to its size and parts used (thrust washers instead of bearings) just wondering what other people thought..

    Makes physics sense. Not sure if anyone has hard dyno data here. It's not just the washers either. An 80 has more drums and more bands to clamp them. There are less stampings and more castings in an 80.

    The gears in a 80e are much are bigger and absorb more power to turn them.

    Not only that but the gearing is kind of MEH compared to the 60 IMO. Now if they made a 5 speed with the 1st gear from the 60 and the other 4 gears from the 80 that would be a monster...

    Boy I disagree. A stock 60 has horrible ratios. 1-2 is a killer. An 8- just requires more rear gear because it's close ratio. A 200-4R has the best splits of the 4-speeds but an 80 is a close 2nd IMO.

    look at actual size you can see its larger then the 60. that there should give you an idea

    2002 Silverado - 427Lsx w/ Twin gt4202s
    2010 Silverado crewcab Z71 - 5.3litre w/ procharger
    2000 Wrangler - 5.3litre with some stance

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
