My requirements... what to build?

DO NOT put a check ball in the "R" hole...
LOL...
My son and I were putting his shift kit in at his work on one of the lifts (he's a mechanic) on this day off. We're goin through the instructions and I asked him how do you interpret this? He says it looks like they want you to put a check ball there.. I says okay damn the torpedoes... We put it all together and it works great except there was no reverse LOL.. I called the Transco hotline and they said did you put a check ball in the "R" hole?... Yup... They said take it out... So back down the valve body and the flood of transmission fluid LOL.. check ball out of "R" hole reverse works perfect LOL...
