I know where i can find the spring for the carb, but where can I find the spring that attaches to the bell housing on the transmission to the kick down arm on the valve body. This is for a 904 transmission if that makes a difference.

mine's an internal spring? The arm returns itself.

You can still get repos, Try Bill at Hiteh Auto GTX6970 If not then anyone who sells repo stuff will have them.

There is no linkage return spring at the transmission end, the linkage return spring is at the carburetor end.

some diagragms showed a spring down there but they are incorrect...spring is on top by the carb linkage

the only kickdown springs used that I'm aware of

thanks everyone, I am getting close to starting it and thought there was a spring down there too.

Throttle pressure linkage....not kickdown linkage

I pulled a 46RE out of a 2001 van this weekend, it had a spring on the pressure lever that went up to a small bracket where the shifter pivot rod bolts to the transmission. I looked at an old 727 in the garage and noticed the lever had the same hole in it that the spring was attached to.

For what ever it is worth.
