A part throttle 3-2 downshift can be accomplished by depressing the accelerator far enough to raise modulator pressure to approximately 90 psi. Modulator pressure and the 3-2 valve spring will move the 3-2 valve against direct clutch oil and allow modulator oil to act on the 2-3 valve. This moves the 2-3 valve train against governor oil and shifts the transmission to second speed as shown in Fig. 23.
