727 or 904?

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

A clogged vein in the valve body or partially? Maybe a bad piston wall in one of the servos? Not holding a band tight? Not sure how that works I'm not like a transmission Guru, just spitballing.
