Having 2-3 shift overlap - Thinking of switching from 4.2 apply lever to 3.8

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

Kim, I think you’re talking more about the 1-2 overlap. The OP is talking strictly 2-3 overlap. The LBA valve body can create a little bit of 1-2 overlap, which is where the dual spring servo, and second gear lever ratio can help take care some 1-2 overlap. But the LBA valve body has no bearing on 2-3. The low band is already fully released by the time the transmission is shifted from 2nd to 3rd. The 2-3 overlap is solely the release of second gear band while the high gear clutch is being applied. Not telling you anything you don’t know. But I think there’s some confusion. That’s where we both agree with the dual spring servo, less ratio lever, and high gear clutch clearance, with spring count, all matter for that 2-3 overlap.
