    There is/was a free C3 in the 'freebies' section, ok it's off a 2.8, but it might fit...?


    EDIT, sorry, it's gone...

    I would take it to your local trans guy. He should have the tools and the knowledge to put it back together properly if he's been in business for at least 15 years.

    i answered above but you could pull the bellhousing/pump assembly off and use it as a whole thing. Check for feed hole differences and bush sizes/ring pack depth but i'm pretty sure C3's had the same pump arrangment on all the models.
    Make sure as you're pulling it off that the direct/fwd clutch drums don't move or you'll need to pull it all apart. Hold the input shaft with the palm of your hand whilst pulling the bellhousing off. Use 2 people. You still might have trouble if the gasket sticks..

    On a C3 no.You need a tool to line the pump up to the bellhousing as there's no dowels.. If you know a machinist they can make you one. It has to fit in the pump bush tight and on the stator support tight to line them up properly
    Without it you can get pump whine from misalignment.

    Ah....Yes,they can break that easy.The gears are cast iron.
    You'll have to pull the trans out.Hopefully you've only broken the gears and not damaged the pump housing and torque converter.
    You should ALWAYS put the trans in by hand,tighten the bolts by hand whilst checking the converter is free. Any binding and you need to stop and find out why.Tightening the bolts on the trans without any of this always ends up in disaster..
    I always suggest to people to have a minimum of 2 doing this kind of job,preferably 3.
    Don't take it to heart. Just call it a lesson.I've known very good mechanics do the same thing. I get calls all the while. Hello,i've just fitted an engine/trans and got no drive...
