thanks for that let me ask this if i could . I bought a b&mtranspak #10228 for a 727 out of a 1970 fury III all original so they say and i have no reason to dought one owner car. I am useing the street mode , put the valve body does not have it all, the down shift assembly is just the cover on the valve body, and there is no spring in the middle of the booster valve assembly. Is this ok also if i am looking down at the valve body the 1-2 and2-3are the only valves the picture shows 1 above those two is that a different year or what.thanks ED
