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

MobileCustoms said

I pulled the servo and it has just one big spring as shown. The second photo shows the only other spare springs I have on hand. Either one of them fits inside the main large spring. Should I consider adding one of these to it?

Also, I checked the kickdown band adjustment which was set at 1.5 turns out from snug. I adjusted it to 2 1/4 turns out and made a note label for future reference as shown in the 3rd photo. I do also have a 3.8 lever on order, to have in hand if needed.
I've seen so many different views on what's best. Anyone else got any input to add? @fishy68
Thanks.

I would not put one of those other big springs inside the original one. That can create a bind when it’s applied, then not want to fully release, and smoke the band. I don’t run the red sonnax servo but I know it’s not designed to function that way with the two big springs. And if I’m wrong, and it is designed to function that way, it’s news to me. The dual spring servo has a 3/8” rod, with a small inner spring, and large outer spring. I would get a new servo from A&A if it were mine to help the 2-3 overlap. Or just run it the way you have it and call it day lol. The 2-3 overlap will always be there, but minimizing it is the goal.
