727 accumulator spring

Folks have been tossing out the accumulater springs for years. It was the original DIY shade tree shift kit. I'm not surprised to hear yours is missing. Some like a instant transision from one gear to the next and some dont.
Instructions that come with a actual shift kit should state keep or disgard the acc' spring. If those instructions dont say toss it out we have to assume keep it.
I'm sure someone here has one if you need it. Good luck

p.s. Without the spring the piston will go to the bottom of the bore and sit there, no slamming back and forth. You could put a block under the piston to hold it to the top of the bore.
That piston doesn't have a sealing ring so fluid does bypass it regardless where it sits in the bore.
