I am contemplating a swap of two transmissions, both of which use a PWM TCC and PC valve. The problem is that the valves operate on different frequencies between the two transmissions. This swap has been done before but I can't find anyone who is willing to tell me how they did it. I found this converter but it doesn't get me exactly where the frequencies need to be:

How close do they NEED to be?
The original valves operate at -42hz and +614hz. The valves I'm wanting to go to are +32hz and +292.5hz respectively.
The frequency is determined by the TCM, I think the valves are just dumb valves for the most part. Does it even matter what valve I use? My understanding of the way that these things work is basically the valve can't open or close all the way as fast as the TCM applies voltage and therefore the amount that the valve opens is proportional to the overall duty cycle being put out by the TCM.
