New Rebuild No forward gears

Did yer builder "AIR CHECK" all clutchs & servos? what hard parts were replaced in it? I assume this is a 727 yer worken on here & there a few diffrent input/foward clutch drums. I ran into this same issue About 12yrs ago when i learnen the trade & i swaped in a erlay foward/input drum into a later (non lock up) foward/input & like a dumb a$$ i didnt aircheck it & sure enoph no foward gears. The later ones have 3 seal rings where the erlay have only 2. Huge leak! just my exp.
