Still studying my recently acquired '01 EB Expedition 5.4. Seems like it goes from 3rd gear right to lock-up 4th. When it comes out of 3rd, it goes right to its final RPM in 4th OD and never drops again. And when it has to downshift, it goes from its initial RPM in 4th OD immediately to 3rd, downshifting. Can anybody tell me if this sounds odd to them? Any chance it's never even locking up? Thanks.
