'90 Ranger 4.0 Auto Refuses to shift

[ColtraneGP]

Hey all, the ol'e mighty PBB sent me this way.

My Ferd is sick!

Just snapped up a '90 Ranger XLT for my younger brother to use as a DD.

Only problem is that at 314,xxx KM - the auto tranny quit shifting on its own.

I didn't have a chance to drive it when it *was* shifting properly - downside of a fifty-buck truck.

I did a fluid/filter change on it yesterday, the pan magnet was clean but the fluid was *well* used.

Still won't shift. Any tips pointers? Let me know if y'all need more info too.

Could be as simple as no vaccum to the modulator, or a bad modulator.
