Hi!

Sorry for my bad english, but iŽll try to do my best!

A Friend of mine want to rebuild his Dynaflow from his Ž56 Buick but he doesnŽt know if it is the stock tranny!

Were their different trannys in Ž56?

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:

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