2006 Chevy 3500 HD 6.6 Isuzu Diesel 6 spd Allison Auto Trans 6331 miles When I come into a town and coast down from 70 mph to 40 mph the trans stays in 6th gear lugging the rpm to 1100Needless to say it gets pretty jerkyI have a Hobart 10k welder, Oxy/Acetylene bottles, Huge air compressor, and a 3ton 21 ft Auto Crane, Replacement filters for detroit 8v71 and 8v92 engines, 1 set swabs and liners for garner denver 4 1/2quot; mud pumps, 10gal 40w oil, 6 gal antifreeze, 5 gal 90Wt., and a complete master set of mechanics tools (sockets and wrenchs up to 3 1/2 quot; ) quot;oil fieldquot; The truck is weighed down pretty good.It was purchased as cab chassisDoes anyone know of any updated calibrations that might address this issueKeep in mind the symptom is intermittantI just think it should downshift on it's own at 1100 rpm's maintaining 42 mph.I checked alldata and got nothing.The dealer was a waste of time too.Please Chevy Guru's, tell me I have the wrong VB,PCM or calib.
You know what is exciting?.the stinky, unwashed toilet stalls in a large mall, especially when it is busy, like around Christmas The fact that you can literally get arrested for having sex adds to the thrill of it, along with people banging on the door, peering over, etc Another trick is to sneak into hotel rooms and empty rooms in senior citizens complexes (usually around lunch time)Broom closets/ laundry rooms in apartment houses work as wellBUT, if your inexperienced try to find someplace you will not be disturbed.
Yes there is a new calibration for the TCM that will address that issueIt was released May 28, 2006 and I've fixed 2, both with utility bodiesFind another dealer if their giving you the run aroundIf you know or can get your current calibration for the Trans control module, post it and I'll confirm if yours has or needs the updateA Tech II scan tool or equivalent is required to read the calibration
my door is always open ;)
