RE: Trans cooler transfusion confusion
You are trying to mix to different generations of transaxle into one,
probable a bad idea. On the bell housing of the trans is a trans code, it is
3 letters followed by 5 numbers by the upper right bell housing bolt. I.E.
RDG 08 03 5 which means an RDG trans produced 08 day of the 03 month of
the 1985 . According to Bentley you could have a RDG (10/82 - 12/83 prod) or
a RDN (01/84 -> prod) transmission. The RDG has a "recirculating system
3-row" cooler and the RDN has a "supply flow 3-row" cooler. Of course there
is a footnote, the RDN as of 4/10/85 has a 5-row cooler. If the housings had
the same fluid passages you could conceivable install both coolers and plumb
them into the coolant hoses but I doubt I would try it. Audi trans coolers
are know to fail and 2 would double your chances of failure.

Subject: Trans cooler transfusion confusion
Got a differential to repalce the busted one, but it looks
replacements cooler was on the rear of the trans, and mine
is on the side.
I see one (the aft one) plug for the cooler, and ...that's
all. The forward
hole seems like a blind, untapped hole.
Is it possible to convert a rear cooler diff to a side
Drill and tap?
