Check Trans Alarm-- Country Coach

Recommended Posts

Recently bought a Country Coach with 4000 Allison transmission. After two days of getting a acquainted we started our first trip to bring the coach home. Getting on the first entrance ramp the check trans light came on and the coach went into what I know now is the "limp home" . After shutting down and retiring the coach the fault cleared but several more times same series of events.

Tech support from dealer with calls to Allison (I think) produced the check specific connections clean, and lube instructions. Traveled several miles with tech and fault did not reappear. Tech left and fault happened several more times. Dealer alluded to another CC that had the problem but cured it by turning on the cruise control. After laughing at the suggestions, desperate, I tried this to get back to dealer. It worked! Not one fault and the coach drove beautifully all the way back to the dealers lot.

They have been unable to diagnose themselves so it goes to a Allison facility Monday. Anyone with suggestions on what to watch for, similar problems and/or solutions?

Coach is an 2007 with 12,000 miles and truly appears brand new. Tech even remarked the bay containing all the electronics "appeared as if it just drove off the showroom floor". Also no previous problem according to original owner.

Thanks in advance for any input here.
