1961 to 1963 slant six 904 trans swap

[Wallus57]

Anyone know if the 61 904 trans will work in a 63? Both are slant six. I haven't looked under the 61 yet, but I think it will have a park brake on the back. Can I just unbolt that and carry on?
Thanks for any help, Wally

If it has a park brake on the back then the output shaft and tail housing are different.

First introduced for use with the push-button dash controls, the early 904s still used a cast-iron bellhousing and a ball-and-trunnion-style output yoke, but the physical dimensions and weight were smaller than that of the older TorqueFlites. They did not use a flex plate to attach the torque converter; instead, the crankshaft on the six-cylinder engines had a large eight-bolt flange to attach to the torque converter.

Flex plates and linkage shifting were added for the 1963 model year, and the output shaft was converted to a standard slip yoke in 1965, the same year the larger-cousin 727 was released. A904 transmissions were original equipment on all 170, 198 and 225 six-cylinder engines, as well as the 273, 318 and 360 (two-barrel) V-8 engines until 1978.

Thank you very much. This was exactly the information I was looking for. Back to the drawing board, lol.

Someone I know had a '61 361 and that had the larger crank flange. No swapping it into a '62 or newer.

Wow didn't know this. My '65 273 Satellite has a 940. So why the SB 727 then? What applications were those used in?
