89 van trans goes forward in P,N, & R

suddenly, when auto trans in 89 voyager 3.0 v6 is shifted to R it
tries to go forward. Will only roll in N if engine shut off, tries to
move forward in P, R & N. Goes forward and shifts just fine
forward.

Had a shudder in trans at start acceleration for a week before this
happened. That is now gone.

What could happen is a range selector out of adjustment or an internal
clutch failed and dragging.
Have you checked ATF level and condition?

Yes, trans fluid full, and not burned look or smell. Probably not
range selector, as the car seems to be always in forward, PRNDL, but
not with full power, though will not roll backward in N without engine
off. Seems to want to go forward less when in R. Still tries to go
forward in P, but locked in trans park position. Car drives
perfectly forward, shifts smoothly, etc.
