Tango,

When you say "rest of the kit", do you mean the B1 accumulator springs? It is supposed to soften out the 1 to 2, iirc as i dont have the manuals in front of me. Did you check your vac pressure on the transmission vac line? If its softening of the shift you need, try turning the transmission modulator a full CCW turn (softens). I've tweaked mine back up to firmer shifts (CW) after I cleaned out the overboost solenoid (vac transducers is the official name) and the other vac transducer near the strut
