For 48 years my 727 with a fairbanks shift kit has thumped so hard and has overlap shifting manually, i finally pulled the valve body. I got rid of the shuttle blocker rod, putting the accumulator spring back in along with the missing ball bearing in the d hole. I also just drilled the passage a little bit next to that ball.
Its now almost stock except the separator plate.
Question is what size restrictor for front clutch. A&A thought when i mentioned .100 was alright. trans go , bm are 130-140 but i have the stock line spring, not the huge trans go springs. So i might need more than .100? With headers its torture pulling vb shift levers, so hate to go to small. The .100 sure looks small to the 11/32 (.344) in the case now.
A&A said maybe turn psi 1 turn over stock. Also bough a part throttle valve from them. I will let u know how that feels,
thanks in advance.
