CAF valve bodies

[Kizza]

Hey fellas I've searched high and low for info about my 200-4R and it's CAF valve body but can't find anything. I now it started life in a 1986 Pontiac Grand Prix but can't find anything on the shift qualities of these boxes. Anyone know if a little grinding of the governor will work to raise the shift rpm? I will be using a transgo hd2 kit with the servo in my cruiser '61 Impala with around 400ish hp.
I tried to look through the 750 odd threads but couldn't find anything.

Thanks

What's the gov. look like?

Very similar to the bottom one. I've got a transgo kit coming.

Valve body has the pink or purple paint mentioned whenever performance valve bodies are mentioned. Actually is CA1 on it.

How high do you want the shift points?

It's no race car and I don't think I've reved it to much past 4500 with the powerglide to be honest. It is pulling very well still at that rpm. I guess around 5000-5200 would probably be fair I guess.

I don't know what calibration the transgo kit has but I should be able to manually shift if I really wanted to. And just leave it to shift however it is set.
