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 1100. Needless to say it gets pretty jerky. I 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 1/2" 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 " ) "oil field" The truck is weighed down pretty good.
It was purchased as cab & chassis.
Does anyone know of any updated calibrations that might address this issue. Keep in mind the symptom is intermittant. I 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.

Yes there is a new calibration for the TCM that will address that issue. It was released May 28, 2006 and I've fixed 2, both with utility bodies.
Find another dealer if their giving you the run around. If 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 update. A Tech II scan tool or equivalent is required to read the calibration #

The vice grip suggestion is sturdy besides the undeniable fact that the writers missed that once you unscrew the nut you need to also attempt to tug as not straightforward as attainable. do not set the vice grip any harder than you want to. Too tight and also you may distort the nut too a lot it may no longer seize. the idea is to objective to regrip the threads or although metallic you may... i do not imagine i might want to apply lubricant till the nut is properly stuck on the threads. possibly want to apply a lever to emphasise it onto threads. are you able to employ the wheel itself to adhere to emphasise to the nut? initiate taking the wheel off till it pushes on the nut. different sturdy answer, if it truly works, is damage it off with the wrench, replace the lug later. in my view i might want to apply an perspective grinder and reduce/grind all of it off...lugs and nuts are not not straightforward to interchange.

Get in touch with GM And tell them the problem.Remember there is a lemon law in most states.I took my truck back 6 times and was ready to turn it in after changing several parts they found a wire shorting against the manifold.If you have time leave it "till it's fixed.

It actually sounds to me that you are having torque convertor problems. If this is the case this a heck of a lot cheaper fix than a tranny.

The mechanics at askautopro.com might know. They're pretty smart and might look up this stuff for you.
