In the accumulator body sonnax uses different accumulator valves and you can fine tune each shift for desired shift firmness with little round shims. Dont use over 3 shims, i dont even recommend using 3 shims, ive done it before. :jester: Gave me whip lash!What do you mean by this? I'm unfamiliar with it.
I've looked at the kits from Diesel Innovation and other places, but haven't seen anything about shims or .427 modulator valve. Its just listed as Sonnax Valve - Tricumulator Springs Kit. Where are the shims and the .427 valve obtained?
I like to use the .500 in tow trucks or for crazy people who love extra firm shifts and plan to beat on the truck hard.ok,youll need the tricumulator spring kit,1-2 shift valve,2-3 shift valve,3-4 shift valve(shims come with valves)and the line press mod valve .427,i was told by a ford tranny guy that the .427 is what to use,there is a .500 but that seems to be too much.also the toque on the valve body is 100 inch pounds,i did say inch.
