How to disable Turbo 400 kick down?

joespanova · 11-24-2017, 10:03 PM

On my street driven 69 Chevelle with a 496 ( plenty of power ) I don't want the kick down functioning.
I've already disconnected the kick down solenoid , now I apparently still have "modulated" kick down function.
How can I completely disable the kick down?
Thanks in advance.

You could put a full Manual valve body in it

Is that the ONLY way to disable it? C'mon , there's gotta be another way.

Why don't you call a local transmission shop?

Did you try screwing the modulator adjustment in?

Might have to screw it out, then re-work the governor, now that I think about it.
Not your normal S/SS question, Joe.

Because.....its Fri. night , its 10:30 and I want to know , now.

The modulator and "kick down" function isn't so clear to me.....I wanted to delay the 1-2 shift so I increased modulator tension , to solve that.
Now how all this relates to eliminating downshift / kick down......I have no clue.

Well , you're in luck then, Joe because I'm here in Az.
Find the 3-2 valve and block it so it won't move. 2-3 should work fine with absence of gov. and mod. pressure for downshifts after slowing.
