Im building a trans with a transgo shift kit, I have a .500 valve and corvette servo. But I didn't get .300 valve.
It's a 92 700r4 trans and it has a .283 (.282 measured) valve in it.
That is bigger than the min valve the instructions call for, but I see the .300 valves out there and it isn't that much to get one.
I am sure I would be fine with the one I have, But do I need to go ahead and pick up a .300?

And just so we are clear, I do not care if this transmission snatches the filling out of my teeth when it shifts.

It is for my play toy, I have a daily driver for smooth shifting.

 

The .300" intermediate/reverse boost valve will give firmer 1-2 manual shifts, and higher line pressure for reverse. The .296" intermediate/reverse boost valve is much cheaper, and is close in line pressure. How much horsepower here? Do you manually shift the transmission? Or leave it in Drive for going WOT?

 

Thanks for the reply, I will be under 400 up and manual shift all the time. (Have ratchet shifter)
