V8 Quattro Transmission install in 200

[Ben Swann]

I'm in process of installing 5-Speed transmission from V8 Quattro and am running into
some difficulties I did not foresee.  The original transmission input shaft sheared.  I
got the car after transmission was removed - the P.O. sold it too me when he got the
uber high estimate to install a replacement transmission. 

Anyway, the main issues I'm having involve the transmission oil cooler parts.   There is
a pump cover mounted to the transmission that interferes with the downpipe flange right
side.   This cover is where one of the oil cooler lines attaches.

The whole transmission in fact was nearly impossible to fit above the dual oulet
downpipe, but so far I've managed to do that, figuring the other trans came out so I
should be able to get this one in.  I managed to clear the dual downpipe flanges and
move bellhousing to about 2" from the engine, but now the one of the downpipe flanges is
jamming on the oil pump cover where the line attaches.

I think I need to disconnect the downpipe to continue installation, but want to make
sure there are no more ugly snags.  I understood that this was a doable conversion and
others might know more about caveats on the install.

Also, what kind of fittings go into the trans?  There seems to be about 12mm hole with
o-ring inside the pump cover.  This pump cover is located on the front bottom right
around the CV axle flange that may be held captive by nearby 8mm bolt, but really I
havn't the foggiest of what goes there and how the cooling setup is.  There is another
hole in the rear of the transmission.   I think the same size and type but since I
filled the trans with fluid, the minute I take the plastic plug cap out, fluid gushes
out.  So before I go any further, I need to obtain at least the fittings that go in
these two ports.

Does the trans use a separate cooler?  ETKA pictures are not clear and show lines going
the engine radiator - that can't be right. 

Anyone have fittings and lines?  It might be good to use a bypass line for now untill I
can source the correct cooler and line setup.  Would use of a bypass line
restricted/unrestricted be a problem?

Any more information on doing this install would be appreciated.  So far I have beat
myself up good on this install and presently it is jammed in the tunnel.

TIA,

Ben
