fluid type for A-518

I installed a Martin Saine VB on a 46re and he gave me a short spacer (piece of pipe) to go in the accumulator instead of installing the spring back in. I kept the spring however. The trans would shift pretty hard. I don't know if removing the spring made it shift like that or just the VB or little of both. Maybe someone can explain the purpose of the spacer.

It was probably a combination of both that made it shift super firm. The spacer is needed because without it the accumulator piston would slam back and forth when hydraulic pressure hits it. Without a spacer to hold the piston stationary it will eventually break.
