Allison 3060 won't switch from Neutral to Drive

My first mechanical issue with the bus. It started this week. Sometimes it wont go into drive. Reverse works great. After playing with it some more today, it will eventually go to drive. Sometimes it works right from the start other times I have to work the button some before it goes.

Prokchop found this article for me. http://forum.bacrallies.com/m-1304866747

It maybe the transmission touch pad. I will talk to the maintenance manager that I bought my bus from and see what he says. If it is, find out where they get them from.

I got a surprise from the maintenance depot I bought the bus from. I stopped by today to ask about this problem and they gave me a new switch assembly.

He told me a work around that is working for now. When you push in the button, wiggle your finger around until it makes contact. This will do me until the weekend, then I will have time to replace it. Since his work around is working, it is pointing to the switch as being bad. I don't think the ECU cares if you wiggle your finger or not.

Re: Allison 3060 won't switch from Neutral to Drive

I bet this is in the ecu...

if bFingerWiggled then
bPutBusInDrive := True ;
elsif
bFailAndLeaveStranded := True ;
end_if

You know I think I did see that line of code in there.

What is that awful stuff, Visual Basic or somethin'?

My Allison pad feels like it has dome switches under the plastic sheet. I guess it makes sense that the dome could oxidize or otherwise develop a poor contact. That's awesome that the maintenance guy gave you a repair kit. I wish I knew anybody at a bus depot 'round here to go and pester with my questions from time to time..

Before I bought the bus from them, I just stopped by and told them what I planned to do with the bus. They were very receptive and answered any question I had.

Haha... It's structured text, which is a machine programming language. It's actually pretty easy, which is good, because it's what I work with all the time. I just saw I had an error, though. "Elsif" should have just been "else", since there was no other "if" statement
