Hello all, I have an '84 C20 350 automatic, it seems to shift well from a stop, but when I get to a slight grade it will not drop into a lower gear. It used to, but no longer and as a result of course the engine will rev but that's it. Of course I can manually shift into a lower gear, then up into second and on into drive after picking up speed or cresting the hill but it won't get it on its own and the same goes for down shifting when attempting to pass or just merging into traffic, engine revs with no push from dropping into a lower gear. Torque converter? Fluid is fine, looks and smells good. Anyway, wondering what the brain trust can come up with, I miss that old performance. Thanks very much in advance.
