Hey guys. I'm debating an M5OD swap sometime later this year, but I want to get all my ducks in a row before I even consider it. I have a 91 Sport A4LD/1354E which I've been slowly rebuilding. The trans still does "OK" but I'm starting to drive this truck farther and farther away from home on little roadtrips, and the aging slushbox is always in the back of my mind. . . I hate the thought of being broken down and stranded.
Anyway, I picked up a cheap 94 Sport for parts, with M5OD and 1354E. It has 150K miles, runs great and SEEMS to shift good as well (it is complete minus the rear differential, so I can't actually test the trans).
My question concerns the ECM. I know I can't use the 94 ECM in my 91 truck, but the major issue is that I simply can not located a 91 manual ECM anywhere near here. I work at a NAPA Auto, and I would typically just order a "new" remanufactured ECM, but there is a whole laundry list of possible ECM calibration codes, and I'm not sure where to start.
F17F-VA
F2PF-ZA
F07F-ZA
F17F-XA
etc, etc, etc. . .
I assume some this concerns power windows/locks, Electric shift Tcase, Cruise Control, etc. . . Does anyone know how to read/decipher the factory ECM codes?
Also, it will get a new LUK clutch kit and all new clutch hydraulics. Is the metal 1991 style Slave Cylinder preferable, or the plastic bodied 1994 stye? Also would you guys recommend LUK hydraulics or stick with new OEM ford parts? In recent years I M5OD swapped a Bronco II, which was fairly easy, so I'm no stranger to this, but I wasn't nearly as particular about the BII. This truck is very special to me, reliability is KEY, and I want it to look/perform like it was a 5 speed from the factory, no shortcuts on this one.
Sorry for the long post. Thanks a bunch for any help.
