1957 power seat transmission

[gary griffin]

My seat only does one function so I think I need a transmission to get it working correctly.

The seat transmissions weren't used until 1960. Your 57 has 3 'spinning' nuts. Each is a threaded nut with a solenoid surrounding it and it locks into place depending on switch position. These are 57-58 only. I'm sold out, but can source one for you if you'd like. Jeff in CT

Gary,
Here is a picture of the guts end of the seat track system.
Note the square "nuts" locking things that were mentioned before.
Note the levers that are attached to each, which cause the seat to move up-down, front-back and so.
Note also the springs at both ends of the assembly, which assist the specific "nut" that causes the motion.
The actions are caused by one nut or the other engaging while the remainders simply move back and forth along the threaded rod.
Engage each nut individually to detect which is not working.
Also make sure the springs are not broken.
Hope this helps you to fix a small problem, not requiring a full replacement.
Have fun,
Steve B.
