RE: Allison Transmission Questions Just wanted to give everyone an update. Before I got a chance to pull, clean, and re-install the main connector as recomended by RWOODY (thx Woody), I had an appointment to get a new set of rear tires put on the motorhome before our annual Christmas trip. When I went back to pick up the motohome, the shift tower would not shift, and after a few seconds would go dead. I recall reading about this (someone else with a 94 Dynasty had the same issue) on this forum, and as I recall, they had to replace the ECU. Being a CoachNet member, I called and had the coach towed from the tire place, to Southwest International (the only Allison certifide facility I could find open on a Saturday). They found a short in one of the batteries which seemed to correspond with the low voltage fault from the ECU, so they replaced both, but this didn't fix the problem. They then sent the ECU out to be reprogrammed, being told that often when there's a low power fault, the ECU can loose it's programming. They reflashed the memory, and are now telling me the ECU is good (at least according to their bench test). While plugged into the bench computer, they downloaded several fault codes. All fell into the categories of Low Voltage, or input/output sensors. The ECU is now back at the shop, waiting to be re-installed in the motorhome. Hopefully that will get done tomorrow. Does anyone have any idea what would cause the ECU to power up for just a few seconds, then go dead? Turn the key off, and it does it again. My symptoms are identical to the fella on this forum with the 94 Dynasty, but I can't seem to find his post now, nor how his situation turned out.
