Dynaflow identification help needed!!

[soulbrother]

Hi everyone! I'm having problems with the Dynaflow in my 1955 Century. It has obviously been disassembled and altered with in the past and the guy who rebuilt it for me recently says some of the parts inside do not seem correct for 1955 as far as he can judge. Also,the reverse does still not work properly after rebuilding so I´m in the market for a used 1955 Dynaflow,either to contribute parts for mine or to be rebuilt and tested in the car. So far I´ve only found one used Dynaflow here in Sweden and the seller isn´t sure what year it is but he thinks it´s 1954 or 1955. I have been told there were changes made each year so I really don´t dare to buy anything else but a 1955.
Now for my questions:
Is there any easy way to identify a 1955 Dynaflow from casting numbers or such? The used trans I have been offered has these casting numbers:
Main housing: 1342982-10 or possibly 1342992-10,not sure about the 6:th digit,looks more like a 9 modified into an 8.
Rear housing:166131-4
Stamped into the thin housing next to the left accumulator: 010
And further to the top: 19 T5 in small digits and 14605-52 in bigger size.
I think my trans has the text "Twin Turbine" casted somewhere,maybe on the bell housing,but not sure since I cant get under the car and check now. Should the 1955 Dynaflow have that?
I have several photos of the used Dynaflow with close-ups of the casting numbers and other details,measures and so on. I can e-mail them if useful.
Thanks in advance!

Have a look at the codes for the dynaflow in the upper right of this page and see if it seems to work for your transmission.

Thanks Bob. I´ll check for the letter. Do you have information on what letter is for 1955 series 40/60? Couldn´t see it on the side you mentioned?
Are Dynaflows for 1955 series 40/60 and 50/70 different length?
Got any measures and where to measure from-to?

Thanks!
