With GM transmissions when the clutches and bands wore to a point where it was no longer within the computers "normal" operating parameters it would default all shifts to full pressure to reduce slipping, GM's failsafe (so I hear) to reduce any further wear/damage to the transmission. The shifts alone when it's in that mode are rough enough to tell you something is clearly wrong. I'm guessing that Maybe this Ranger is doing the same thing.
@gusherb94; I don't think that Ford uses a pressure transducer. I know what you're talking about though. GM's are relatively failsafe, but like the 4L60Es, the forward clutch usually is the first to go. Every one I've seen apart had the forward clutch burnt up. I think with this one, I believe it's a 4R44, and I think it's an issue of a throttle valve cable being out of adjustment or missing. I'm going to check to see if there were ever any bulletins.
