yes you can
Modulates pressure that controls shift points.
You lift the hood and look at the pressure gauge.
Your transmission is most likely a 4T60E. If so, it has no modulator valve. This transmission is electronically controlled from the ECM. Line pressure, which is what the old modulator valve controlled, is now controlled by an internal pcm solenoid.
Lift hood. Locate area between engine and transmission, look down, follow the vacuum line from the maifold to just above the starter. The unit screwed into the side of the tranny with the vacuum line coming out is the modulator.
on the side of tranny, about mid point on passenger side, there is a vacum hose on the end, with a single bolt clip holding it on
Th350 has a modulator on the back. Th400 has modulator on side. 700R4 has no modulator.
