I installed the B1/B2 accumulator springs, the B1 control valve spring, the K1/K2 control valve springs(2) and the TV pressure control valve springs (2).

Initially, with the valve body still installed, I had replaced the K1 accumulator spring with the purple spring and installed the shorter, blue spring in the K2 accumulator spring train. The results then were very good; the 2-3 flare (which was the major problem) was gone and the 2-3 & 3-4 shift quality was excellent. It's when I tried to go from 'very good" to "perfect" that things went downhill.

The vacuum levels at the vacuum control valve are 15" at idle, 5.5" with the test disk installed. I have 23" at the pump.
