No there is not.
That year did not use them. It is electronic controlled transmission.
That transmission does not have a modulator valve on it. It is computer controlled to a point.
In the fuel tank.
If your speaking of the vacuum modulator for the transmission, they no longer use them on the transmissions with overdrive and electronics. The powerglide, turbo 350 and turbo 400 used to use them.

It is mounted on the top of the starter.

im stuck and I need help
If your 1990 Chevy silverado is a short bed (6 foot), 350 cu. in. V8, and you're using the rear bumper to tow from, then the capacity is 4000 pounds. The tongue weight is 400 pounds.
It is under the dash where the passagers feet go.
disconnect the hose and remove 2 bolts.
That year did not have one. No need for it on that one.
NO. The transmission in that truck is electronic. They STOPED using a modulator valve back in the late 80s.
