Get's confusing doesn't it...but only the AUM is actually a transmission code.

Go back into your EKTA and check the AET and AAT listings again.  Let me know 
if any say 5 speed, 6 speed, automatic or sliptronic.  I'll bet you a pint of 
Moosehead they don't.  I'll also bet you another pint that they have numerous 
listings by vehicle model with very specific dates probably starting mid-late 
'80's.

If you want the decoder ring...you can buy one from Bob Myers.
