    my 4L60e is slowly on its way out .....again , was drinking with some buddies and we figured it be a lot cheaper to change a clutch than a whole trans + i could run a lot steeper gears if i went with a 6 speed... but i imagine its pricey .

    Just imagine all of the extra beer i could have bought instead of buying junkyard 4L60's

    When i bought my truck initially i was shopping around for one with a 5 speed, all i found were 4.8s and 4.3s !
    I was told they weren't avalible with a 5.3, something about the back of the crankshaft being diffrent, do i have to drop the crank and have it machined to accept the pilot bearing and input shaft ?

    Was wondering how hard this is to do and who here has done it

    4l60e to 5 speed
    or
    4l60 to a T56

    What did it cost, was it worth it? etc..

    Thanks

    im not sure of everything needed to do a t56 swap but i do know that you'll need a crossmember from a 5spd truck. also, you'll need the slave cylinder from an ls1. check out fullthrottledan and 1truess on gmfullsize.com both of these guys have done the swap
    13.4 @ 98mph. Cammed/Stalled/LTs/Tune and those lame 3.42s!
