Went to junkyard and found '94 Cougar. Shifter was very tight (unlike mine). Took whole shifter unit out to replace. Yes Buck, MLPS is bang on the mark. I have 3 of them I have tried in chasing this, the original, brand new Motorcraft, and a junkyard one. May not have time to get it in and test tonight, but think it may solve the movement issue.
Also yes, I repinned the bulkhead connector to the tranny to match EEC with the new sensors.
