    In this thread I will detail the cleanup, teardown, disassembly, and rebuild of a '96 47RE to 48RE specs, using upgraded 48RE mechanicals - the designated victim is on it's way, even as we type: a '96 47RE that broke at 90kmi behind a hi-output 12v Cummins CTD built for pulling - it is the 4wd model

    The rebuild to 48RE specs will be using the PATC Ramzilla kit with a 'billet' triple-disc torque convertor

    This will include a billet one-piece input shaft\hub, billet intermediate shaft, billet output shaft;
    Alto Red Eagle master rebuild kit plus 2 extra clutches and 2 extra steels,
    rigid Carbon intermediate band,
    Fairbanks TransAction kit,
    5 clutch direct drum,
    performance 3-4 accumulator spring,
    heavy duty low\reverse servo,
    heavy duty no leak intermediate servo cover,
    5 to 1 ratio intermediate servo band lever (actual ratio to be determined),
    full time torque converter fluid feed valve,
    Mega Spring for more holding power in 1st - 2nd and 3rd,
    heavy duty intermediate band apply strut.

    Plus the following Extreme Duty and 48RE parts,
    all three 6 pinion planet gears,
    sun gear and shell,
    front and rear ring gear,
    shell race,
    front planet sleeve,
    3 thrust washers,
    overdrive backing plate,
    forward clutch backing plate,
    overdrive brake backing plate,
    300M input shaft,
    1 extra overdrive brake clutch and steel and 23 overdrive single sided clutches.

    Can't wait to see what broke and what survived - if the case is undamaged, we're good to go.................

    Just installed the TRANSGO 48RFE shift kit in #2 son's '06 BigHorn Ram 2500 - folks, it ain't easy like a GM trans - I never saw so many trinkets, doodads, jimcracks, thingamajigs and dinwhiddies - shoulda done my 47RH first as prep for that bad boy (so as not to look bad in front of my kid, which I did!) - but, all's well that ends well, and I'm really satisfied with the upgraded shifting response and firmess - next: a lower-stall hd tcc, then SUPERCHIPS reflash - then on to the 47R rebuild as an option for my truck

    Sorry 'bout the delayed response, but, yeah, the video should make things go easier - also, the GM boxes are easier than the Dodge, with it's multi-piece valve-body

    how hard is swapping a valve body on a 47re if I just buy the valve body done like a BD.
