I know it sounds stupid but...... Take a hair dryer to the Tranny ECU. May get you going. Also I assume you have unplugged it, cleaned the contacts and reseated it.

I spoke with John Kopalek, he's the one that repairs the original Alison computers, and he indicated that the replacement that I have is not sensitive to heat as the originals. I did remove the connectors and reseat them to make sure that wasn't the issue. The thing is dead as a doornail.

Which outlet are you taking the coach? Thank goodness you're only 70 miles from Tucson!

Global Trans in Tucson has a "transmission" section on their site you can click on. Click on "troubleshooting" and scroll down to "Main Code 23" and "Subcode 12" & "14". Could that be you? Allison Transmissions and Detroit Diesel Engines - Global Industrial Automatics

Cant read codes with a dead unit. My shifter does not light up.

Roland, have you disconnected the connector at the shift pad and checked for voltage on the connector plug pins with the ignition on?

No and I should have done that. I thought about doing it, put it off then forgot. I got involved with something else and it completely slipped my mind. Will give it a shot in the morning.

Sorry, got on the wrong thread, someone else had the "cat's eyes" and subcode 12 & 14 mentioned those.

Hey Roland,

How you doing? Any update on your situation?

Not yet. Will be going to Tuscon today and will go to the Allison dealer there for a confab. Will keep y'all posted on my progress until I get it resolved as I don't like open ended threads.

Spoke with Richard Andrews at Arizona Transmission. I got a couple drawings from him that I have never seen before. There is, according to these drawings, a "VIM" unit between the ECU and the touch pad. And there are two 10 amp fuses inside this unit. Problem is I can't find this "VIM" unit. This sound correct to anyone?

I know you've been busy and probably didn't notice, but I mentioned the elusive "VIM" back in reply #18. I kept running across reference to it on other forums. If we have one of these boxes on our coaches, I sure haven't ever seen it. I don't think we do, but I could be wrong. One way you could check would be to test the continuity of the wire between the "always hot" 10A ATEC fuse (under your dash cover) and the power pin on the ECU plug. If the wire running from the ATEC fuse is the same wire supplying power to the ECU, then there must not be anything in between. Or at least if there is anything in between, it is not "blown".

Chuck, according to Richard Andrews the VIM unit should be next to the ECU. Sure not there on my coach. Going to overnight my ECU to John Kopalek tomorrow.

I find measure some voltage at the shifter input but was not the five volts that Richard claimed should be there. Would but a new ECU "IF" I was certain mine was bad. Don't have to get the coach towed to the dealer if I can identify the bad component. That's a relief. Campground here is willing to "work" with me.

Does anyone have an electrical diagram that includes the shift pad?

If one exists, I sure haven't seen it. It is easy to find Allison diagrams (online) showing the wiring between the trans ECU and the remote shift pad. Those are the same diagrams that show the mysterious VIM box. The problem is, when Foretravel tied the Allison transmission electronics into our early GV coaches, they apparently didn't bother to document the wiring circuits that were added to the coach. My Owner's Manual says I have a Allison MT 647 transmission, which shows you how accurate it is (we have a 6-speed). And, my wiring diagrams don't even show the 3 ATEC fuses which are plainly present in my fuse block under the dash cover.

Roland, I would send the ECU and the touch pad to John, that way he can tell if it is one or the other.

I used the diagram I received from Richard Andrews to measure the voltage going to the shift pad. I have twelve volts between pin 1 and point 7 on the RSI connector. My display does not light up. Seems to me it should. May have a display problem not an ECU problem.

Will send my ECU to John Kopalek if I n believe I should. But right now I'm leaning to a bad shift pad. They don't give those away either but it's a bit less then an ECU. The new shift pad does not have a membrane it has switches and they have one in Benson. Just may go pick it up and see if I lick out. Really want to get back to Ajo.

OK I am out of the barrel, time for someone else to jump in. Replaced the shift pad and we are good to go. Was treated very well at Arizona Transmission in Tuscon. Got a break on the price of a new shift pad. We are under way and headed back too Ajo.

Are you coming here to Shadow Ridge or going up the hill? I'd like to see that heater you put in. Maybe someone will put LED lights in that barrel, gets scary after a while!

Shift pads don't look cheap on ebay. If you don't mind me asking, what were the damages?

Will be interesting what Roland paid. I just looked on Ebay, and my #29507949 pad was $900+change!

I was charged $540.00 for the new style shift pad. This shift pad does not have the gel pad it has switches. Worked for me.

Not at shadow ridge. Not up the hill either. Found our own little spot.
