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

Thanks. I’m running type F but would have to open it up further to verify the other things unless I can find some old photos. I planned to put the same fluid back in that I drained out. Not sure if switching fluids would be safe at this point?
Actually, the 2-3 overlap is the worst if I'm coasting and shift to 3rd. This is a street driven car, mainly.

I’m definitely a fan of Type F no doubt. But in a street car Dex/Merc is way to go in my opinion. It’s not an issue if you switched to Dex/Merc right now. It may not make a HUGE difference with what your experiencing but it’s not going to hurt. I didn’t realize it was mainly a street car. I would put a Dacron filter in as well.

I guess I explained it poorly, basically pull foot back off throttle and bump into 3rd real quick, kind of simultaneously. I can understand a true coast you would feel the overlap more. If you don’t pull front pump and drum out, I’d at least verify the second gear servo has dual springs, and if it doesn’t, I would certainly make that change. That will help the overlap because it will allow the band to release quicker.
