I did upgrade to the 0.500" TV boost and 0.283" Reverse boost, both with O-rings and both sonnax parts from my local transmission parts house.

I am not sure which spring you are referring to because i only know them by the names given in the manual. I assume you are talking about the Throttle valve spring in the valve body, but there is also a spring between the reverse boost valve and pressure regulator valve in the pump. Please let me know which one you are suspecting.

Should both of these springs be replaced?

thanks in advance for your patience with a newbie
