Also known as 30TH (A404-1.7L); 31TH (A413-2.2L); 31TH (A470-2.6L); 31TH (A670 various engines).

 Versions of this transmission were used from 1978 to present.  There were MANY variations over the years and MANY parts do NOT interchange from year to year or model to model.  DO NOT confuse it with the overdrive A604.
