Were their different trannys in 56? He gave me this three numbers of the tranny 1346645-4 casting number: 1342992-3 166692-4 Thanks for your help! Martin
Here are a couple of links that might help. The first one is a discussion on the '56 Dynaflow trans and the second one should help with the identification: http://www.v8buick.com/showthread.php?t=141983 http://www.teambuick.com/reference/ident_automatic.php
