I once had the same problem, drove it home from Kentucky, parked it then 2 weeks later, dead dark panel...would not start!

Here is my thread and what I had done to get it resolved..

It really isn't that difficult to troubleshoot just take your time and follow logical steps.

NP...

I would start by unplugging and re-plugging all the transmission wiring connectors under the bus by the tranny first.

If any of the connectors, which receive alot of moisture and dirt, have any kind of poor dirty connection or as in my case a rotted out wire connector, that could easily cause a no power to the push pad.

I did it backwards... disassembling where the push pad is located is not hard but also no fun.
If I had to do it again, I would first re-seat all the connectors first.

for one, make sure the battery has juice. im assuming you have done that.. secondly there are fusible Links that go from the starter terminal to some of the battery circuits.. they look like little blue or pink wires, I had one of those go bad on mine and so I would check for 12 volts in both sides of the fuse cavity on the dash.. ie take out t he fuse and test for voltage on both pins in the socket to ground.. black lead on ground, red lead on each terminal.. if one terminal had power I knew I had power to the fuse box.. one of my ECM terminals did not have power at the fuse box.. tracking it back I found a broken fusible link (one of the small wires of the many on the larger starter terminal from the battery).. the fusible links look slightly different and are short.. like 6 inches or so so they are pretty easy to spot.



if your ECM bat and trans fuses all have power to one side in the fuse box then you know you need to troubleshoot from the fuse panel toward the device..



is it just your shift panel is dark? or is your bus ECM dead too? no WARN light when you turn key on?



there is a Power relay that must come on before the ECM will come up.. this is handled at Key on.. I cant tell you physically where it is on an RE bus.. its on the bulkhead on a conventional.. if that relay is bad you will get no pwoer to the shift pad or the ECM when you click the key on

The whole bus is dead. I have to jump over the starter to get it to start. Im checking voltage at the tcm. 26 pin is supposed to have 12v. It doesn't. Ive traced it to the fuse box and am trying continuity

So the engine starts if you jump the starter as opposed to using the key or the rear start ?

I just noticed that my battery charger signals yellow. Not green even after I've been charging all morning. That sounds like a dead cell

1998 should be a single computer on the side of the engine..



it sure seems like your starter-enable relay is failing to engage.. that relay is used to disable the starter if an interlock is off .. i also wonder if because the trans pad is dark that it means the neutral safety switch fails to engage..



a dead cell sounds like a good possibility but your engine starts if you jump the starter.. that says ot me the computer boots up or the engine wouldnt run, and the battery has enough juice to start the engine (which means it has enough to run the computers)..

No VIM on this bus. It has a large fuse/relay box. Grey connector tcm. Pin 28 is yellow and .08 volts give or take. Pin 26 is pinkishgrey. I need a pin out for this vehicle. The one online is for a vehicle with VIM. Cannot locate the right one. Id like complete pinouts for ecm tcm valve body and digital shift box. Can you help?Click image for larger version

I have to tow this thing. This walmart isnt 24 hr. But i can get to good wifi. I was thinking about the international dealer but not sure they do Allison. Most likely.
I feel like in close tho. I think i have to tow it to another walmart. Haha

you are right the pink wire going to the shift pad is the plus power for it and it gets its power from the TCM, so it looks like the TCM is probably missing power on one of its circuits.



1998 is a pivotal year but if your engine has the single computer I thyink your transmission should be WTEC III



you may have seen this already but I found this onine.
