96 Bounder E4OD issues
New member here, but have found lots of useful information here in the past, including clues to the current issue.
Background: Bought this coach a year ago with only 54k miles on it and in great condition. Good maintenance records from PO including Ford reman transmission replacement at about 38k miles at a Ford dealership. Service record indicated necessary replacement as coach had been driven with parking brake on. That assembly was also replaced. Coach was in storage for most of the past 10 years before we bought it. When trans went into limp mode at about 58k miles we chalked it up to perhaps dry and cracked seals even though oil was clean and full. A local shop in Grand Forks ND rebuilt it in 3 days and got us back on the road, claiming to have put in heavier duty parts. 5k miles later we're now stuck again in OR. 2 rebuilt transmissions have been installed, rig has been given back to us 2x only to fail within 2 miles of leaving shop. This after successful test drives by the shop.
Currently no codes, MLPS, ECU, PCM replaced. We've spent days googling and have learned more about E4OD than we ever wanted to! What's curious is that there is no VSS on the rear dif and no pigtail to be found. There's a plug in the hole where it should be (photo). I have found a wire connector tucked into the frame behind the generator that has been disconnected since before purchasing the rig. Noticed while doing other maintenance (photo).
Also curious about this coiled up plug in the front driver's side next to the large fuse box/ relay panel (photo). BTW, Cruise Control has never worked. Research says Cruise Control, VSS, and ABS are all necessary for correct transmission operation. I believe I could really use a F53 wiring schematic and an E4OD wiring schematic which I haven't been able to locate if anyone has them.
Any advice appreciated!
