Talked to A and A

I talked to A and A about my soft 1-2 shift problems,under part/light throttle it shifts nice and firm under full throttle it's soft.They recommended upgrading front band and installing 5.0 lever.My 2-3 shift is good.Before I start buying parts I just wanted some opinions on this.The trans was rebuilt locally with I'm sure standard parts.This is a street driven car,no track time.Has a mild 360 w/a 2200-2500 stall converter and 3:55 gears.I don't beat the car much it would just be nice to be able chirp second gear. I've got the kick down adjusted properly,I think,timing is fine,unless I tighten it up more which just pushes 3rd out further.They said I wouldn't have have 2-3 overlap on a 904 w/a 5.0 lever.Any thoughts on this?
