Hello Angel,
Here is the info they wrote up:
"Tech confirmed failure key fobs using recommendation doc 1861180 put system to sleep removed rcdlr reinstalled fuse retested all OK"
Since they did this fix a couple of months ago everything has worked fine. Hopefully your dealer can find out what that document says.
Good luck, let us know how things work out.

differential work - switching to 4.10 rear end?

I have a 2001 Yukon XL 4wd w/ a 3.73 rear end. The rear end has some noise and the dealer told me it's likely the ring and pinion gear needs replacing. The car goes into the dealer this week. Since the rear end needs to be rebuilt could I switch to a 4.10 rear end? Would I have to do something to the front end differential since it's a 4wd?
thanks in advance for any advice

I have a 1998 GMC Yukon and I have received the same code. I have lost my reverse, 2nd gear seems to function when it so chooses and 3rd gear is almost non-existent. I can drive it, but it's like a stick shift with a bad clutch?
I was curious to know the details about the replacing of the solenoid and what it entailed since I seem to be in the same boat.
I am not brave enough to venture into a tranny blind, so I was going to AAMCO tomorrow.
Any guidance would be greatly appreciated.

The paint is chipping off the navigation console buttons exposing the yellow plastic under them. Does anyone have a fix for this? (Other than GMC-- I've been reading about their stepping up to the console paint issue!!!!)

Do you know what the RPM is when the lights are flickering?? Do the dash lights flicker at the same time?? Does the rate of flickering change with a change of RPM?? Have you had starting problems?? Does the engine seem to turn over slower after the vehicle has been off for some time???

RPM's make no difference. Flicker rate does not change with RPM. Yes, dash lights and all other lights that are illuminated flicker at the same time. Vehicle is new (5K miles) No starting or turnover problems. It doesn't do it when cold. Vehicle has to be operates 10 minutes or more. I'm thinking perhaps the diode trio in the Alternator. Your thoughts? Thanks..

My shade-tree mechanic opinion is that it is not the diodes but rather the voltage regulator. The key is that the flickering does not change with RPM and the added information that it does not flicker when cold. I think you are seeing the voltage regulator turning on and off after you have fully charged the battery and it is just regulating in a "maintaining" mode. If you want to definitize that, throw a load on the battery by doing something like turning on the fan or driving lights while the lights are flickering. I'll bet it changes the rate for a few seconds. If your dealer has some old guy working there I bet he has an old dial voltmeter and he would see the needle move in sync with the flickering you are seeing. The young guys should have something like an oscilloscope to see this. ( He will have to wait until the battery is charged and the regulator is "idling" before he tries this). Hopefully you have not added some 3,000 watt boom box to your electrical system that does massive current draws and GMC won't talk to you. Now for the bad news. Some people are much more sensitive to flickering lights that others. If other people riding with you don't see this flickering, it might just be your sensitivity to differences in light levels. Good luck and let us know how this comes out.
