Had the same problem last Feburary. Mechanic had to pull the starter to get to the main engine connecter. He also said the info being downloaded had to share the lines with the trans.  Have had it done since and there wasn't a problem. makes me wonder if the problem was a poor connecter or connection.    Jim Nichols

Denny Wagaman,
I have a Cat C-9, 400 horsepower engine in my 2005 Monterey coach. I had a software update done last fall, at Wagner Cat in Denver. The update basically allowed more fuel to flow to the engine at startup, until the engine water temperature reaches either 150 or 160 degrees  ( I can't remember which). The engine idles much better now, at cold start up.
Good luck.
Stan Anderson
