5KQ and 200Q transmissions

[rpp <75313.1445@compuserve.com>]

Hi all,
I was wondering if anyone could confirm whether the transmissions are the same
for an 87 5KCSTQ and a 91 200TQ.  I was told that the one in the 200 was an 016
tranny and I remember from the Bentleys that the 5K was an 016.  If this is
true, does that mean they are 100% interchangable or is the gearing and/or
housing different?  I want to know cause I have found a 200 for sale with a
transmission prollem and the dealer has the old one out already.  I figgr if I
can get the one from my totaled 5K into his 200 I could buy it extra cheap (so
he says).
Any and all help would be appreciated.
