    The oil plug in the transfer case has completely given up and the torx socket is soft as cheese. Today's challenge is to get it out.

    If you have a welder, u could weld a nut on it. That would give you something to get a wrench on, and the heat will usually free up the piece... Otherwise heat around it with a propane torch to expand the metal and try to get it loose.

    On second thought, it looks brass, just heat the area around it as welding won't work on it.

    When you did your overhaul, did you replace the bearings?

    While waiting for the zf parts order I took a closer look at the exhaust.

    Took the o2 sensors out and they do not look brilliant. I am thinking these will be replaced.

    And this is the weld between downpipes and flexpipe. Someone did this exactly wrong.

    Also, I don't think I should be able to see straight through the catalytic converter:)

    Isn't that the flex pipe? That should be hollow.

    Sorry, bad picture. The flex pipe connected the downpipe to the cat.

    I have been chasing the zf seller for weeks. There is a holdup because of one of the items but I can't get a straight answer as to which one. It's really frustrating.

    Finally the parts arrived!
    I thought the input shaft came as a complete assembly but I had to take out the old piston to reuse and noticed a torn o-ring.
    Annoying but it's on order.

    Assembled the valve body with a new transgo valve and put in the f and e clutch yesterday. Some progress...IMG_20180522_232611.jpeg

    Yeah it's under way.... Another success story in the making. That o ring could easily be a major part of your previous issue

    Got the final o-rings yesterday and put the a and b clutch assembly back together without much problem:)

    When taking the transmission apart I measured the distance from bellhouse face plate to the input shaft to 39 mm.

    The assembly slides in quite easily but now only to 34 mm.
    Going through videos and manuals trying to figure out what I'm missing...IMG_20180317_134652.jpeg

    You replaced some hard parts, right? Like a drum? That can change measurements. Look for a spec for that distance and see if you fall within it. We are talking 5mm, right? My gut says it should be fine, but look for a spec. That 5mm seems damn close.

    Exactly, I have replaced the a clutch drum.

    The problem is that the the c clutch metal plates are really hard to get to line up exactly right to allow the a/b clutch assembly to fall into place.

    It has to go all the way in for the pump to sit flush.

    Did you have any problems getting the a/b clutch assembly in?
    Any suggestions?

    After an incredible infuriating day yesterday of not being able to get the a/b clutch in I gave it another try today. It went in on the first attempt!

    Here it is in all its fully assembled glory.

    Very happy:)IMG_20180614_214655.jpeg

    Sorry I didn't get back to you sooner, a/b clutch is last one in, right? If so that's why I had the trans standing upright on an engine stand and let gravity pull it in, took a couple trys to get all the way in. Congrats, man
