I believe that is what Avanti referred to it as in their sales literature. I know that it is not what GM called it. Link to comment Share on other sites More sharing options...

mfg Posted May 31, 2018 Author Report Share Posted May 31, 2018 studegary, & r1lark,....Avanti Motors did refer to the new transmission by the names you mention, however, we're looking for the actual 'GM' name for that transmission. Link to comment Share on other sites More sharing options...
