a904 to 727 swap help!

There's only one "long" tailshaft length for a 727, but the slip yoke is different, and you'll have to have a shaft made or yours shortened.

Make sure IF you have a console, that the 727 has the cast-in mount underneath for the shifter linkage. You can look at your 904 to see what it looks like.

You'll need a different torque converter, 904/727 do not interchange. I BELIEVE there were two different input splines over the years on 727, and be sure you don't get a "lockup."

Don't know if the kickdown pivot mount is different --mine has a broken stud, and I don't use kickdown, as I use a manual shift body.
