My car '80 300TD would not shift into high (40 mph max).  Donor car is '81
300TD (what it says on the outside).  While removing engine & tranny I says
to myself  "this 300TD engine ain't got no turbo?" -- that's strange!  The
engine was seized, the middle connecting rod came unglued and had the crank
in a bind, got it free enought to get the torque converter bolts out. So, I
have my tranny out, ready to pull my other car up and slip it in.  As I
pulled my car up and to looked under it to scope out the situation, I
noticed that the trannies don't look alike -- different electrical
connections, the donor tranny has a part number ending in -85.  Could this
be an '85 tranny?  Its electrical connector appears to be in a straight
line.  My original car has circular pattern, from what I can tell -- it
connects differently anyway.  My question is -- can I successfully swap
these transmissions?  Can I splice the connectors?   The plug deal is just
park/ netural start and back-up lights -- correct?  The kick-down wire is
separate.  Got to get it together -- kid starts school in a week!  Thanks.
