More aggressive friction material changes shift timing and feel, some need more line pressure to apply properly. Also extra material can change the pack's clearance, so one has to go by what is normal for that particular set.
Have fun tuning band application. That will **** off a preacher. That is why units that only shift via clutch packs are easier to tune.
Low stall converters also make the unit shift firmer.
FWIW, I always start at the mildest settings for any valve body kit. You can always make it shift firmer, going in reverse is way more of a pain

The spring I was talking about controls the line pressure. Of course, the line pressure effects everything.
Yes, I know that once you start installing more clutches, more aggressive clutches, kolene plates, etc, it's going to take some time to dial things in. It did.
I did play with the converter orifice too and eventually dialed that in too.
When I was looking into this, I did not see anyone mentioning that leaving the stock pressure regulating spring alone. I am just sharing if there are any other fools out there that is going to add everything to make a firm shift [including the accumulator springs] you might just pause on that spring. Or at least save it in a special place because you can't find a new stock spring anywhere. Having a Tweecer allows me to dial in the pressures/shift timing which is just icing on the cake.
The next time this transmission is coming out, is when the 408 is installed.
