Dear SF:1990 chevy silverado wont shift into drive or
overdrive r,1,2, work fine.

SF:
Hello, these conditions signify a failure in the forward clutch assembly or the forward
sprag. Basically an internal transmission failure. The trans. will have to come out and be
overhauled, or a rebuilt replacement installed. A rebuilt unit will have any updates that may
have been released for this trans. since the unit was built.
