Kickdown band lever ratios

Leadfoot said

I'm going to have to differ with you on that one. Not for the sake of argument of course. Simply for the sake of understanding. As you can see as the ratio increases the indent that the interlink sets in gets increasingly closer to the center of the fulcrum. While it will take longer to engage the opposite should happen on the release. Thus the release should occur sooner. Unless I'm just not seeing things right.

Greg's actually right. Yrs. ago when I first looked at them I thought the same as you that the 5.0 lever would apply and release faster but it doesn't. Just as the driveshaft on a vehicle with 4:10 gears has to move farther (more revolutions) than a car with 3:23 gears, the higher ratio lever causes the servo to have to move farther to apply the band. If you notice the recommended adjustment for the 5.0 lever is 2 turns, where-as the adjustment for a 3.8 lever is more. The servo only has so much stroke length so their making up for it by having you adjust the band tighter.
