Having 2-3 shift overlap - Thinking of switching from 4.2 apply lever to 3.8 - Any Other Thoughts?

Well then u shouldn’t have bind up. In order for that to happen the front band comes on b4 the rear band fully releases. I would put 2 springs into the front servo. So then I suspect u don’t have enough clearance/springs in the front drum. U need bare minimum .020 thou clearance per clutch plate. Even as much as .025 wouldn’t hurt. So with 5 fingers u need at least .100 tho clearance. What was done to the accumulator if anything? Switching levers may help a bit. U may have to loosen it more than recommended. The reason for less gap for the higher ratio levers is that they have to travel farther to clamp the band on. They also have more holding power. Hope this helps. Kim
