727 or 904?

Isn't the line pressure adjustment Just in that bracket on the valve body next to the pressure valve itself? I was wondering how those effects without the shift kit would be? Like when I did a stage 3 on a 904 there was a few different adjustments for that line pressure.
Yes it is located there. But he said his throttle valve was not adjusted correctly. If that were the case the pressure may have been not enough for how far his foot was into the throttle. Regardless of the base line pressure setting the pressure is modulated by the throttle valve. How could he fail 3 second gear bands in a row.? Imho
