K/D super servo's

2-3 overlap is when the band hasnt fully released and the direct clutch applies giving a bump feeling shifting to third. some think its a firm shift but acually two gears on at the same time. ive seen some builders use the large pin servo and take the tiny spring out and shim it with a washer and put the snap ring back in. this takes the accumulation out of it and kind of makes it like the early small pin servo's. i see that the rigid bands are comming back in style, but to expensive for a normal build. good for a high torque diesel though.
