BlueSteele Posted September 5, 2022 Share Posted September 5, 2022 I have been a silent observer on this forum for about a year. Over that time, I have had the chance to scan the many daily entries and sometimes read them entirely including the comments. I don't have a great expectation of finding solutions to my problems because of the age of my 38 foot1993 Monaco Dynasty. She's an older machine. Many of the issues don't apply to my rig being pre-emissions (pre-DEF, anyway). My Allison MD3060 has the WTECII shift button ECU from 1992. I have had such good fortune with this unit that I was surprised when I had an issue. During my monthly run-up of the engine and generator, my shift pad blinked from "N" to "NoShift" then it went blank. I shut down the engine and tried to manually re-level the coach (sorry no auto level back then) but got no response from the RVA Model J2 leveller control pad, other than the power indicator light. I tried to restart the engine, but no response. Something was very wrong. I had to use a bottle jack to level the coach on one corner. I searched this forum for something to help with the troubleshooting and found a few posts that pointed me in the general direction of the faulty WTECII ECU. I called Allison Transmission with my serial number and they admitted that the older WTECII units were prone to failure, but offered no real troubleshooting guidance. I checked EBAY for parts availability and was put off by the crazy prices for used replacements with no assurance that this would resolve my issue. Randomly, I searched YouTube and found one guy who had the same exact experience as I. He had his ECU rebuilt in the Dallas, Texas area and was extremely happy. His video gave the link to the company : Transmission Instruments (www.transmissioninstruments.com). I scanned their website with great confidence that this was the solution! John Kopalek, Owner and Senior Engineer of Transmission Instruments had prepared a troubleshooting guide that is very specific to the ECU's he rebuilds. I followed the troubleshooter and pinpointed my issue exactly! I bundled the ECU for shipment following Mr. Kopalek's instructions. Within a week, I had my rebuilt ECU back in hand. I installed it today without incident following the installation instructions included with my ECU. Everything works and my coach is completely level again.
