Failure Date: 12/22/2012

On 12/22/12 @ 5pm- shortly after entering onto the freeway, I started losing power. I didn't get higher than 50 mph before the rpm started increasing & my speed started decreasing. I got off the freeway, at the first exit, approximately 2mins after the beginning of the loss of power. Found a mechanic that was just closing his shop & asked him to give a quick check too see if I could continue my drive home, 32mins away. The mechanic checked under the hood & under the bottom & guesstimated the problem to be the flywheel. The mechanic also recommended no driving til repaired. I got my Avalanche towed home that first night. I towed it to my local auto repair shop on 12/24/12, to get a full diagnostic. I was advised by my local mechanic that my 2005 Avalanche w/ 96319 mis, needs a new transmission. My local mechanic advised it may still be under warranty due to mileage, but I have since found out the warranty is 5yr/100000mi. Gm is aware of premature transmission failure on the Avalanche, but is not fixing it for the consumer. Something needs to be done to protect the consumer!.

Vehicle transmission failed at 73,500 miles. Vehicle just stopped in middle of highway while traveling at approx 45 miles per hour. Subsequent rebuild by mechanic revealed that gm had installed incorrect valve body gaskets in the transmission, likely contributing to the premature failure.

Failure Date: 02/19/2008

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.

The contact owns a 2007 Chevrolet Avalanche 1500. The contact stated that his transmission failed while driving approximately 55 mph. When the accelerator pedal was engaged the transmission acted as if it were in neutral and the vehicle failed to move. The dealer replaced the transmission at 16,000 miles. When the second failure occurred a rebuilt transmission was installed at 26,000 miles. The current and recent failure mileage was 36,000 and the dealer stated that they have to install a rebuilt transmission. The manufacture was notified and the vehicle will be repaired per the warranty. The first failure occurred at 16,000 miles. Updated 10/30/09 the transmission would not go beyond first gear. An internal fault was found in the transmission. There was damage to the input housing at the pump cover seal area. The blower motor was inoperative. The power steering shuddered at low speeds.
