Hello everyone. My friends 62 Fleetwood has over 100,000 miles on it and the transmission just went out big time. We are looking for a replacement. I am assuming any Cadillac Hydramatic from 59-62 will fit because those are all the same 390 blocks? I don't think 63 will work because I know they changed to block that year. Please correct me if I am wrong. We are trying to find all of the compatible Hydramatics to widen our search. Any input is appreciated.
Thank you

63 also works. It is the same transmission.
I have a 62 transmission in the shed. Too bad shipping from Canada would be the equivalent to murder

Thanks Dan. Yes shipping would be insulting. I'm going to post a thread in the WTB section. Just wanted to see what my options were.
Thanks again

Gavin:
No good business case can be made for removing the presumably original and correct but inoperative transmission and substituting a similar transmission of unknown functionality or fluid-tightness. I would never put a "used" transmission in a car, too much work to take the risk. I would first rebuild it, at least re-seal it, and so then why wouldn't you simply do that with the transmission you have? If you split the case drag racing or something like that, well OK but otherwise...???

Dan,
VERY well said!

1959 and 60 transmissions will fit but you need the 59/60 starter as the 61 to 64 Jetaways have a starter drive end nose
than has a machined support nose that is absent on the earlier starters so the bellhousing will not accept the later 61
to 64 starters. I first did this very swap 45 years ago.
I don't think the 59 trans will fit the tunnel,they are wider. Ken Perry
I would locate a reliable transmission shop and rebuild the original one. Parts should be available through Northwest Transmission and Fatsco.

I'm sure many "fit" but according to the Motor transmission manual I have, 62 Cad and 59-60 Olds S88 and 98 share the same, 61 and 64 Cad are the same, 63 Cad is unique, 61 and 64 series 75 are the same, 62 and 63 series 75 are the same (I'd surmise the differences being in calibration)
