MARBLES in TAILSHAFT…..

Guys........

I have a 727 Auto that was hooked to a driveshaft which was out of balance....it ate up some u-joints, and vibrated & made you crazy.....didn't drive it much.....I had a new shaft made and balanced, and installed it....Nice.....ALMOST all of the vibration is gone, but NOT quite......

Now, when the car is in Drive and downshifts smoothly at low speeds (around the village....allowing the car to shift itself), when you get to a low rpm in second, and it's ready to downshift into 1st, I hear "marbles" rattling around in my tailshaft......literally........that's the best comparison I could use.

Every time it shifts down at "no-load", I hear marbles.........like the teeth of a gear gently rubbing against something making a "rattling" sound.....

OK.......what's up? What in the world am I hearing, and could this be serious? I'm afraid that when the shaft was out out of whack that it ruined something in the tail shaft............:read2:
