    now I bought this ruined gearbox for $50. congratulations myself. good platform for learning.

    It seems the e-differential hydraulic system has a problem and subsequently damaged it.

    I am not an expert but I seem to now understand that how the e-diff work. It is more of a H(ydraulic)-diff in my opinion , than an E-diff as it is hydrauliclly controlled, just like the throw out bearing

    I have a hard time understanding why half the rollers comes off, see next pics

    Well, the aluminum is easily worth that much in scrap. So, have fun learning.

    why a failed f1 pump to cause leaking ATF inside the gearbox?

    Can you get a pic looking straight down. Would be worthwhile knowing the offset of the gear. Offset was a big part of the discussion on type of gear oil to use (i.e. GL-4/Gl-5).

    you mean after the removal of the pinion gear and take a pic of it from gearside down?

    in the picture in post #4, how far is the hypoid gear axis offset from the main shaft centerline

    but from my understanding , that's not the distance from main shaft centerline to the pinion gear centerline.
    its more like axle shaft centerline to the pinion gear centerline. I am a little confused

    Its amazing that the gears has only an input shaft and an output shaft with counter shaft's functionalities shared on those input/output shafts. I've never seen any manual transmission like this (forks on both shafts!). But I didn't have too many gearboxes opened, to be honest. A,B,C,D,E,F are all fixed gears and they rotates together with the shaft all the time. Usually there's a dedicated lay shaft that has fixed gears and only fixed gears.

    Is it probably because the output shaft and the input shaft faces the same direction? Or is it because of spatial constraints? Or for the sake of saving weight?

    all gears looks good, except this. It is missing a tip. Is this a big deal? useable? Or am I expecting to see something like this even if I open up my own car's gearbox?

    Haha well i didnt say that. Im just saying that chip did nt look that bad. The picture might show it bigger than what it is too. Either way I don't know if that would have an effect on anything like a gear whine or not. Somebody with good experience on these things might come in.

    the whole process of removing the gear sets from the shell. Note that my terminologies aren't necessarily correct. I am a newbie for gearboxes. I just want to show u poeple what's involved and whats inside of these machines, for a reference maybe.

    First, remove the rear cover, picture not shown ,just a bunch of bolts and pry it off.
    1st pic is what you see after remove the rear cover. What I have in hand is a positioning or securing device for the sleeve.
    2nd pic , what im doing is to remove the pin that holds the reverse fork to the control rod.
    3rd pic, now the reverse fork and the sleeve removed.
    4th pic, idler gear removed
    5th pic, now it looks like this
    6th pic, there's a circlip that need to be removed before removing the reverse gears.
    7th pic, remove the plate
    8th pic, now to remove the reverse gear
    9th pic, removed!
    10th pic, now it looks like this
