He is waiting for a control module to engage to start. While I have no first hand knowledge of this issue, I have seen it discussed. Apparently the control module is waiting for some input/feedback circuit which when received engages with a clicking sound and allows the unit to start up and is unique to Allison transmission units.
Thanks fla-gypsy for explaining that for me!! I have posted many post on this issue.But I guess some didn't see it. thank again
All the fancy new phones out there are making Americans devoid of writing skills. We look like lazy idiots to the rest of the world.
Dang I'm getting cantankerous..
ScottG I'm not to sure who the "idiot" is!! As you can see the other guys got it!! sorry for my spelling skills and typeing. I do have A Disability with my education! that said I will not say anything about your profile pic.
Mine wouldn't go into gear because of a bad exhaust break. There are several things that feed into the vim such as idle speed.
If all conditions are not right it won't go into gear to protect the transmission.
There is a good chance it is not the VIM.
You need to take it to a authorized Allison repair faculty.
The answer is above. My problem was the exhaust break.
