2005 Chevrolet Avalanche 1500 transmission complaints

At highway speed, service 4 wd light came on, stated vehicle lost speed/power and the 4 wd selector shifted on its own into 4 wd hi.....very dangerous situation...to lose speed and power in highway traffic.
"service 4wd" started to be displayed erratically in the dic. 4wd system started to function erratically 4wd control switch witness lights light erratically or do not light at all. 4wd low range engaged by itself unexpectedly while driving - this was a serious accident hazard, fortunately it occurred at low speed and at a place where the vehicle could be stopped safely. General motors has issued tsb 05-04-21-003c (april 15, 2008) for this condition however owners were not notified about it or the potential associated accident risk. Research on the web at vehicle owner clubs shows this condition to be a very frequent problem for gm vehicles using the this type of 4 wheel drive. Further research on the same sites suggests that the solution to the problem was a challenge to gm and it was a "hit-and-miss" approach with multiple trips to the dealer to get it resolved. This malfunction could be cause a serious accident if it happens at interstate speeds in heavy traffic or on a slippery steep mountain road ( just to give a few examples).
Car started jerking as if it was going to cut off then once I got on the highway it would not go over 50 miles per hour. Took car to the dealership, and later found out that transmission was gone.
I bought a 2005 chevy avalanche. 3 year 36,000 mile warranty, at 40,000 miles the transmission disintegrated. $3,000 out of pocket........ I expect a little more than 40,000 miles out of a $35,000 truck. Now I'm getting mail about a speedometer lawsuit, I've always been a chevy guy but if this is what I can expect from gm maybe its time for a change!
Normal driving. Gm tsb 05-07-30-017b talks about an issue they have on several thousand 2004-2006 vehicles that can allow for transmission fluid contamination, leading to failure of the transmission. My experience is that under towing, the vehicle can create a dangerous condition if the transmission fails due to unforeseen circumstances. This also can lead to repair costs over several thousand dollars, that the manufacturer, or warranty companies, will not cover. General motors knows by the issuance of the technical service bulletin that this condition exists, yet refuses to educate the owners of affected vehicles, and refuses to correct the issue and damages it creates. I have found several other cases where this failure has occurred with no remedy from the manufacturer.
I own a 2005 avalanche with 2000 miles on it. When turning sharply while in 4 wheel drive, going forward or in reverse, the truck bogs down and stops. There is nothing in the owners manual about this. This is a dangerous condition for someone who does not realize what will happen. If I were to make a u turn the vehicle will come to a stop if the wheels are turned two sharply. My dealer did not even know about this untill I brought it to his attention.the dealer went out on his lot and drove an avalanche in 4 wheel drive to determine if I was nuts or not. Well I am not nuts as thiers did exactly what I said. The dealer then contacted general motors and was told this condition is normal so the u joints and gear box will not be damaged. If they say it is normal to lock up why don't they put it the owners manual? Someone is going to be seriously hurt over this condition and it will be more than u joints or gear box.
