[BuickSchrauber]

Hi!

Sorry for my bad english, but i´ll try to do my best!

A Friend of mine want to rebuild his Dynaflow from his ´56 Buick but he doesn´t know if it is the stock tranny!

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!

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:

There was only one Dynaflow transmission in 1956. It fits all series, and only the 1956 models.
