727 shift point question, automatic valve body

The kickdown only controls shift pressure not shift point. Until you are flat out into the detent for passing gear then that second to drive is controlled by the governor.

One other thing to know is when ever manually shifting a mopar trans always start off in drive. Once the car is rolling then pull it back to low. The shift will be much crisper from 1st to second rather low to second while flat out.. No overlap due to band apply low gear. You want to launch in 1st not in low.. Once it leaves in 1st it will not go to low while moving. Try it and you'll see

Not sure if I’m understanding the low vs 1st and what exactly you are saying here. I’m kind of with you but not 100% here… ?

Once the car is rolling and I pull it back to 1rst it WILL downshift to 1rst no matter what speed your doing, this is a function of the tf2 shift kit from what I understand? (is this the ‘low’ you are referring to?)

If I start in first and shift to second myself at higher rpm it’s fast and firm. Same as second to 3rd (drive) also, crisp, fast, and firm.

I do launch in first. Again not sure what you mean by low?
