Question - Would a 51 Hydra-matic be the same as a 53 Hydra-matic
I have a chance to pick up a 51 Transmission as a spare for my 53 Hornet. I don,t see too many down here in Australia.
51 Trans # 051-279172
53 Trans # H53-12803 --- Currently in my 53
Thanks.

    51 is single range and 53 is dual range hydramatic.

    In addition to what Kerry said, the transmissions are almost entirely different. Virtually no interchange between parts.   Single range was really is the early generation tranny. Dual range began next generation. You could use a 51 tranny in your 53 but you would loose the high -low selection on drive range.

    The Hudson shop manual cautions NOT to interchange HydraMatic parts between different models.  So swapping valve bodies is not a good idea.

    I think there may be a difference in bell housing attachment points between 1952 - 54 as one pattern and 1951 having another. Does someone know ?

    FYI

    I think having a spare Hydro regardless if single or dual range in your Country is a good Idea. My '53 has a single range in it when I bought it and works fine and no plane to change it. The only difference when pulling a steep grade the drop into low is abrupt where a dual range would be smoother.

    I'd highly recommend speaking to long time HET member, Gus Souza, regarding Hydra-matic transmissions.  He's been rebuilding them for Hudsons for at least 30 years.  Quite an expert regarding what will work, fit, etc.,.  Unfortunately, I don't believe he has an e-mail address for you to contact him at.  Perhaps "snail mail or if you're willing to call long distance.
