Kickdown band lever ratios

Leadfoot said

Fishy. I'm not 100% sure that was it. Mostly because in my thinking a 5.0 lever will release the band sooner. I'm going to give that a try anyways. I really don't have anything to lose. I just assumed the converter was in the way. So I never really put any thought into it. If it's not that, I'm pretty well stumped. It's not a real problem as long as I'm going 2-3 under load. When it's not under load I can hear a chirp as the rear tires grab the pavement. Under load it's better but the 2-3 still isn't as crisp as it should be. Sounds like something to do before the Spring thaw.

The 5 lever releases the band slower actually, since it takes more movement on the servo end for it to move the band.
More leverage on the band means more travel at the servo, and therefore it takes more time to move it.
Just putting a stronger spring in there would probably clear up the overlap.

For the 2-3 shift you can open up the direct clutch apply oil hole in the separator plate to get more volume to the clutch quicker but you need that front band to come off faster also, or you will get the 2-3 bind (overlap) again.

If you put a stronger spring in the servo, open the direct clutch apply hole, and use a lever with less ratio you would get a nice quick and firm 2-3 shift.
This is what I would do if were my trans, and it can all be done without taking the trans out.
